Industrial workshops that generate hot, acidic, and corrosive exhaust streams need piping systems that survive where conventional materials fail. The high temperature PP waste gas discharge pipe extruder is the production backbone for manufacturing polypropylene flue and vent pipelines engineered to move workshop fumes, chemical plant off-gases, and ventilation air at temperatures that would soften PVC or corrode carbon steel. Faygo, une usine Wanplas, has spent 22 years developing pipe and profile extrusion lines and brings that depth to lines configured specifically for heat-resistant polypropylene pipe production. This article explains the material science behind high-temperature PP flue and vent pipes, benchmarks polypropylene against PVC and steel, details the real Faygo extrusion lines you can deploy, and gives a diameter-and-temperature selection method to match the right machine to your workshop flue and vent pipeline construction project. Whether you build ventilation ducts for electroplating plants, fume extraction for laboratories, or exhaust stacks for food processing, this guide connects the engineering to the machine on the factory floor.
Polypropylene has become the default engineering plastic for low-pressure, high-temperature exhaust because it pairs a service temperature near 100 degrees Celsius with outstanding chemical resistance and a fraction of the weight of metal. Producing that pipe reliably, with consistent wall thickness and a smooth interior surface, depends entirely on the extrusion line geometry, the screw design, and the downstream calibration and cooling control. The following sections translate those requirements into concrete Faygo machine configurations and documented specification tables so a procurement or process engineer can plan a plant with confidence.
What a High Temperature PP Waste Gas Discharge Pipe Extruder Delivers
A high temperature PP waste gas discharge pipe extruder is a complete pipe production system that converts polypropylene resin, with or without glass-fiber reinforcement and heat-stabilizing additives, into continuous lengths of round flue and vent duct. It is not a single machine but an integrated line: a gravimetric or volumetric feeder, a single-screw plasticizing extruder, a pipe die head, a vacuum calibration unit, a cooling bath, a haul-off caterpillar, a cutting station, and a centralized intelligent control system. The line must hold tight tolerances on wall thickness because a flue pipe that is too thin loses pressure rating and heat resistance, while one that is too thick wastes material and slows line speed.
The defining requirement for this application is thermal stability of the melt. Polypropylene is a semi-crystalline thermoplastic with a melt temperature around 160 to 170 degrees Celsius and a decomposition threshold well above 300 degrees Celsius, but its mechanical properties in the final pipe depend on avoiding thermal degradation during plasticizing. A well-designed PP flue pipe line keeps the melt homogeneous at the lowest practical temperature, applies a barrier screw for thorough mixing, and uses a die head with balanced flow so the pipe wall is uniform around the circumference. These are the same fundamentals that Faygo has refined across 22 years of dedicated pipe and profile extrusion manufacturing.
Wanplas is the parent brand that aggregates the specialized factories, and Faygo is the Wanplas factory dedicated to plastic pipe and profile extrusion. Every Faygo line carries the group quality standard, CE certification, and ISO certification, and is backed by the shared USD 500 free parts per year policy.
Faygo operates three specialized factories and, through its FAYGOPLAST division in Zhangjiagang City, covers 26,650 square meters of production area only two hours from Shanghai Airport. The operation holds 13 national patents, including 8 invention patents, which underpin the intelligent control and barrel-screw geometries used in the pipe lines described here. For a project that builds workshop flue and vent pipeline networks, that combination of scale, patent depth, and certifications translates into a line that is documented, serviceable, and traceable to international standards rather than a generic commodity machine.
The economics of building PP flue pipe in-house are compelling for any workshop that installs more than a few kilometers of duct per year. Purchasing prefabricated PP flue sections from a trader adds logistics cost and lead time, while owning a Faygo line converts resin into finished pipe on demand, at the exact diameter and wall thickness the layout requires, with no minimum order quantity. The resin itself sits in the Medium cost band, far below the Élevé à très élevé cost level of corrosion-resistant steel, and the light weight of polypropylene cuts the cost of supports, hangers, and crane time during installation. For a maintenance or facilities team that regularly reconfigures exhaust routes, the payback on a dedicated extrusion line is often measured in months rather than years, and the Wanplas group USD 500 free parts per year policy keeps the consumable budget predictable.
Polypropylene Material Grades for Flue and Vent Pipelines
Polypropylene is not a single material. The grade chosen for a flue or vent pipe determines the continuous service temperature, the heat deflection temperature, the chemical resistance profile, and the ease of welding. Selecting the wrong grade is the most common cause of premature flue pipe failure, so the extrusion line must be able to process the specific grade the application demands. The four grades most relevant to high-temperature waste gas discharge are polypropylene homopolymer, Copolyamide PP aléatoire, PP block copolymer, and glass-fiber reinforced PP.
Polypropylene Homopolymer (PP-H)
PP-H offers the highest rigidity and heat resistance among unfilled polypropylene grades, with a continuous service temperature near 100 degrees Celsius and a Température de ramollissement de Vicat around 150 degrees Celsius. It is the workhorse for industrial flue and vent duct because it resists most acids, alkalis, and salt solutions and welds cleanly with hot-plate or socket fusion. Its main drawback is lower impact strength at low temperature, which is acceptable for interior or insulated exhaust runs.
Copolyamide à polymères aléatoires (PP-R)
Le PP-R est formulé pour le service d'eau chaude et de gaz chaud, avec une température continue allant de 70 à 95 degrés Celsius et une bonne résistance hydrostatique à long terme. Pour les canalisations de ventilation des ateliers qui transportent de l'air chaud et humide plutôt que de la chaleur sèche, le PP-R offre une meilleure ténacité et une fenêtre de traitement légèrement plus large que le PP-H. Il reste la catégorie référencée par les normes ISO 15874 et GB/T 18742 pour les systèmes d'eau chaude et froide sous pression et est entièrement compatible avec les canalisations Faygo en PP-R.
PP Block Copolymer (PP-B)
PP-B adds an ethylene-rich phase for improved impact strength, useful for vent pipes that may be struck or experience thermal cycling. Its heat resistance is similar to PP-R, and it is often selected where the duct must survive mechanical handling during installation. The trade-off is a marginally lower stiffness, which the line compensates for with slightly thicker walls.
Glass-Fiber Reinforced Polypropylene (PP-GF)
Le PP-GF, généralement de 20 à 30 pour cent de fibres de verre par poids, est la qualité qui élève les performances des conduits d'aération dans la zone de haute température. Le renforcement élève la température de déformation par la chaleur de environ 55 à 60 degrés Celsius dans le PP non chargé à 120 à 150 degrés Celsius, tout en réduisant l'expansion thermique et en améliorant la stabilité dimensionnelle. Pour les conduits de ventilation des usines chimiques qui connaissent des températures continues supérieures à 100 degrés Celsius, le PP-GF est le matériau de choix, et la ligne à un seul vis Faygo le traite grâce à un rapport L/D plus profond et à une géométrie de vis adaptée aux fibres de verre.
Beyond the base polymer, the additive package determines whether a flue pipe survives its service life. A heat stabilizer package, typically a phenolic or phosphite antioxidant, protects the PP chain from thermal oxidation during plasticizing and during decades of warm service. A UV stabilizer is added only for outdoor or roof-mounted vent runs where sunlight would otherwise embrittle the surface. For workshops that exhaust solvent vapors, a flame-retardant masterbatch can be compounded into the resin to slow ignition, though the base polypropylene already carries a useful limiting oxygen index. Color masterbatch is usually unnecessary for flue duct, but a gray or black pigment is common for identification and to mask condensate staining. The Faygo gravimetric feeder meters these additives with the resin so the compound ratio stays constant across a long run, which is why wall thickness and heat resistance do not drift between the first and last pipe of a shift.
| PP Grade | Continuous Service Temp | Température de déformation par la chaleur (0,45 MPa) | Vicat Softening | Primary Flue/Vent Use |
|---|---|---|---|---|
| PP Homopolymer (PP-H) | 100 degrees Celsius | 55 à 60 degrés Celsius | 150 degrees Celsius | Conduit d'aération et de ventilation industriel |
| Copolyamide à polymères aléatoires (PP-R) | 70 to 95 degrees Celsius | 60 to 70 degrees Celsius | 150 degrees Celsius | Conduit de ventilation humide et chaud, eau chaude |
| PP Block Copolymer (PP-B) | 80 to 100 degrees Celsius | 60 to 70 degrees Celsius | 150 degrees Celsius | Tuyau de ventilation exposé à l'impact |
| PP-GF 20 percent | 110 degrees Celsius | 120 à 130 degrés Celsius | 155 degrees Celsius | High-temperature flue |
| PP-GF 30 pour cent | 120 degrees Celsius | 140 à 150 degrés Celsius | 160 degrés Celsius | Extreme flue and vent service |
These values are typical ranges; the exact numbers depend on the resin supplier, the masterbatch additive package, and the wall thickness designed per the relevant pressure or non-pressure standard. The practical takeaway for a plant owner is straightforward: if your workshop flue gas stays below 100 degrees Celsius, unfilled PP-H or PP-R is sufficient and lowest cost; if the gas is sustained above 100 degrees Celsius, specify PP-GF and select a line with a screw and barrel configured for glass-fiber compounds.
Heat Resistance Benchmark: PP vs PVC vs Steel
Choosing a flue or vent material is ultimately a comparison of temperature limit, chemical resistance, weight, and lifecycle cost. The three candidates a workshop usually weighs are polypropylene, unplasticized PVC, and carbon steel. Each has a place, but for hot, acidic waste gas discharge polypropylene wins on the combination of heat and corrosion resistance. The table below benchmarks the properties that matter for workshop flue and vent pipeline construction.
| Propriété | PP (PP-H / PP-GF) | 20 mm | Acier au carbone |
|---|---|---|---|
| Continuous service temperature | 100 degrés Celsius (PP-H) ; jusqu'à 150 degrés Celsius (PP-GF) | 60 degrés Celsius | Very high, but corrodes |
| Short-term peak temperature | 120 à 140 degrés Celsius | 80 à 100 degrés Celsius, libère du HCl | Très haut niveau |
| Résistance aux gaz d'échappement acides | EN 61386 | Good below 60 degrés Celsius | Poor without coating |
| Comportement de la corrosion | Aucun | Aucun | Corrodes with SO2, HCl, moisture |
| Densité | 0.90 to 1.05 g/cm3 | 1.38 g/cm3 | 7.85 g/cm3 |
| Poids relatif | Basique | Moyen | Très élevé |
| Niveau de coût | Moyen | Basique | Élevé à très élevé |
| Joining method | Hot-plate or socket fusion welding | Solvent cement or gasket | Welding or flanges |
| Thermal expansion | Haut niveau | Moyen | Basique |
PVC fails the temperature test for flue service. Above 60 degrés Celsius it softens, loses pressure rating, and at 80 to 100 degrees Celsius begins to decompose and release hydrogen chloride, an outcome that is both a safety hazard and a corrosion source for everything nearby. Acier au carbone handles the heat but suffers rapid corrosion in acidic, moisture-laden flue gas unless it is lined or coated, and even then the cost level is Élevé à très élevé with a Very High weight that complicates support structures. Polypropylene sits in the Medium cost band, resists the acid, and keeps the installation light. The main design caveat with PP is its high thermal expansion, which the layout must accommodate with expansion joints and proper supports, a point the Faygo application team addresses during plant design.
From a lifecycle perspective the comparison is not close. A carbon steel flue needs periodic inspection, coating repair, and eventual section replacement as wall thickness thins from acidic attack, and each intervention disrupts the workshop exhaust. A PVC flue, if it is mistakenly used above its temperature limit, can sag, leak, and release corrosive gas without warning. A polypropylene flue, correctly graded for the operating temperature, runs for the life of the building with only routine joint inspection. The higher upfront discipline of specifying the right PP grade and the right Faygo line is repaid many times over by the absence of corrosion-driven maintenance, which is why engineering specifications for new chemical and electroplating plants increasingly mandate PP for any exhaust above 60 degrés Celsius.
Ligne d'extrusion de tuyaux PP-R/PE-RT de Spécification Faygos
For diameters from 16 à 160 millimètres, the Ligne d'extrusion de tuyaux PP-R/PE-RT de Faygo is the primary machine for producing high-temperature PP flue and vent pipe. Although the series name references PP-R and PE-RT, the same single-screw architecture processes PP-H and PP-GF grades for industrial exhaust once the screw and die are matched to the compound. The line is built around a single-screw extruder with a barrier (BM) screw and a dedicated mixing section, an L/D ratio of 33 to 1, and a die head engineered for balanced, low-stress flow that preserves the heat-resistant properties of the polypropylene melt.
| Paramètre | Ligne d'extrusion de tuyaux PP-R/PE-RT de Faygo |
|---|---|
| Gamme de diamètre de la tuyauterie | 16 à 160 millimètres (PP-R, PE); 16 à 32 millimètres (PE-RT) |
| Type d'extrudeur | Single-screw with barrier (BM) screw and mixing section |
| Diamètre de la vis options | 45, 60, 75, 90 millimètres |
| Rapport L/D | 33 to 1 |
| Driving motor | Fréquence variable AC, 55 à 110 kW |
| Puissance maximale (PP) | Up to 400 kg/h |
| Vitesse de la ligne | 0,5 à 35 mètres par minute |
| Gamme d'épaisseur de paroi | 2.0 to 15.0 millimeters |
| Calibration du vide | 2- or 3-stage vacuum calibration tank |
| Haul-off unit | Caterpillar type, 2 to 6 tracks |
| Cutting station | Planetary saw or chip-less cutter |
| Système de contrôle | PLC plus HMI touch screen, closed-loop |
| Certificationss | CE et ISO |
The barrier screw is the heart of this line. It separates the melting and metering functions so the polypropylene is fully plasticized at a controlled temperature before it reaches the die, eliminating the cold spots and shear heating that degrade heat-resistant compounds. The 33 to 1 L/D ratio gives the melt enough residence and mixing length for stable output even with PP-GF masterbatch, while the AC variable frequency drive lets the operator optimize screw speed against melt pressure for the cleanest pipe surface. For a workshop flue project, the 16 to 160 millimètres range covers the majority of branch and main duct sizes, and the 400 kg/h ceiling supports continuous shift production.
En aval du moule, le réservoir de calibration sous vide régule le diamètre extérieur avec un manchon de dimensionnement sous vide contrôlé, et la section de refroidissement par pulvérisation congèle la géométrie avant que la chenille de transport ne tire le tuyau à une vitesse synchronisée. Une scie planétaire ou un coupeur sans copeaux coupe ensuite le tuyau continu en longueur. Étant donné que l'ensemble de la séquence est géré à partir d'un PLC avec un HMI, un opérateur peut librement définir des paramètres et effectuer des ajustements en temps réel, ce qui correspond exactement aux exigences de contrôle intelligent que Faygo intègre dans chaque ligne de tuyaux.
Ligne de production de tuyaux en PVC Faygo : extrudeur à double vis parallèle
The second real Faygo machine relevant to this project is the Ligne de production de tuyaux en PVC, which uses a parallel twin-screw (or conical twin-screw) core and spans diameters from 12 à 575 millimètres with wall thickness up to 6.5 millimeters. Although its name emphasizes PVC, the twin-screw core is a versatile platform that also runs PP and PE pipe, so a plant that needs both conventional PVC drainage and high-temperature PP flue pipe can standardize on one Faygo architecture. PVC itself is not the flue candidate, but the line matters because many workshops pair a PP flue system with PVC condensate and drainage runs, and a single supplier simplifies spare parts and training.
| Paramètre | Ligne de production de tuyaux en PVC Faygo (coeur à double hélice) |
|---|---|
| Gamme de diamètre de la tuyauterie | 12 à 575 millimètres |
| Matériau applicable | PVC (UPVC), PP, PE |
| Type d'extrudeur | Double vis à vis parallèle ou conique |
| Twin-screw diameter | 65/132, 80/156, 92/188 millimètres |
| Driving motor | AC, 37 to 110 kW |
| Puissance maximale de sortie | Jusqu'à 800 kg/h |
| Épaisseur de la paroi | Jusqu'à 6,5 millimètres |
| Vitesse de la ligne | 0.3 to 12 meters per minute |
| Calibration du vide | Multi-stage vacuum calibration tank |
| Haul-off unit | Caterpillar, multi-clamp |
| Cutting station | Coupeur planétaire |
| Système de contrôle | PLC plus HMI, closed-loop |
| Certificationss | CE et ISO |
The twin-screw core shines for powder-fed compounds such as PVC dry blend, where the intermeshing screws provide the intense mixing and devolatilization that a single-screw cannot. For PP flue pipe specifically, the larger diameter twin-screw options (80/156 and 92/188) deliver the high output needed for big-diameter ventilation trunk lines up to 575 millimeters, while the parallel screw geometry keeps shear and melt temperature controlled. When a workshop flue network requires both small branch duct and large main trunk in the same plant, running the 12 to 575 millimeter twin-screw line alongside the 16 to 160 millimètres single-screw line gives full coverage from one Wanplas factory.
Configuration. de la ligne d'extrusion pour le tuyau en PP à haute température
Producing a reliable high-temperature PP flue or vent pipe is a function of how the line components are configured, not just which extruder is chosen. The following configuration principles apply to both the single-screw PP-R line and the twin-screw core when processing polypropylene for flue service.
Extrudeur et tube
Le tube est équipé d'une section d'alimentation en grain ou lisse et d'un profil de température qui augmente vers la zone de dosage, mais reste en dessous du point de dégradation du composé PP. Les parois de tube durcies et nitrurées ainsi que la vis bimetallique dans la version à une vis et la géométrie d'intermétallurgie co-rotante dans la version à double vis prolongent la durée de vie lorsque des grades renforcés de fibres de verre sont utilisés, car les fibres sont abrasives. La vis de barrière dans la version à une vis et la géométrie d'intermétallurgie co-rotante dans la version à double vis visent toutes deux à une plastification uniforme avec un surchauffe minimal.
Tête de moule et dimensionnement
The pipe die head uses a spiral or baffle distributor that balances flow so the melt arrives at the mandrel and die lip at a uniform temperature and velocity. For flue pipe the die is sized to the target outside diameter and wall thickness per the selected standard, and the vacuum calibration sleeve sets the final dimension while the pipe is still molten at the surface. A 2- or 3-stage vacuum tank holds the calibration with graduated vacuum levels, which prevents ovality and sink marks that would weaken the duct.
Cooling, Haul-Off, and Cutting
After calibration the pipe enters a spray cooling bath sized long enough to bring the core temperature down without thermal shock, which matters because PP has a high thermal expansion coefficient. The haul-off caterpillar grips the pipe with synchronized tracks and pulls at the exact speed set by the line master, while the planetary cutter or chip-less cutter severs the pipe cleanly to the programmed length. All three stations are slaved to the extruder through the PLC so that a speed change at the barrel propagates instantly downstream, holding wall tolerance across the full length.
Intelligent Control and 72-Hour Test
The intelligent control system lets the operator freely set parameters such as screw speed, melt temperature, vacuum level, haul-off speed, and cutter length, then make real-time adjustment from the HMI as the run stabilizes. Faygo builds the line around internationally renowned brand electrical components for dependable sensors and drives. Before any line leaves the factory, it runs a Opération continue de 72 heures test under production conditions, so the customer receives a machine that has already proven stable output, stable wall thickness, and stable control rather than one that is tested for a few minutes on the showroom floor.
Chaque ligne d'extrusion de tuyaux et de profils Faygo est certifiée CE et ISO, passe un test d'exploitation continue de 72 heures avant la livraison et est supportée par la politique Wanplas de pièces gratuites de 500 USD par an ainsi que par la garantie de remplacement.
Energy efficiency on a PP flue pipe line comes from matching the drive power to the actual throughput rather than oversizing the extruder. The AC variable frequency motor on the single-screw line draws only the current the screw load demands, and the closed-loop control holds melt temperature within a tight band so the heater bands cycle less often. Because polypropylene plasticizes at a lower temperature than PVC, the PP line runs cooler and consumes less energy per kilogram of pipe than a comparable PVC line, an advantage that compounds across continuous multi-shift operation. The line also integrates melt pressure and temperature transducers at the die so the operator can monitor the process window in real time; if pressure drifts, indicating a screen pack nearing the change interval, the HMI raises an alert before wall thickness is affected. That level of process visibility is what lets a 72-hour pre-delivery test be meaningful, because the same sensors that proved the line stable in the factory continue to protect it at the customer site.
Applications : conduits d'aération, extraction de fumées et conduits de ventilation
The high temperature PP waste gas discharge pipe extruder serves a defined set of industries where hot, corrosive, or particulate-laden air must be moved safely. Faygo’s pipe lines are applied across the following sectors, each with its own temperature and chemical profile:
- Ateliers de placage et de traitement de surface— la brume acide et les fumées provenant des bains de placage sont chaudes et hautement corrosives ; le conduit de fumées en PP résiste à l'acide et reste étanche à des températures qui détruisent le PVC.
- Tubes d'évacuation de l'usine chimique — off-gas from reactors and storage tanks often carries solvent vapors and acidic condensate; PP-GF grades extend service life above 100 degrees Celsius.
- Laboratory and pharmaceutical fume extraction— Les capots d'évacuation exigent un conduit lisse et propre, chimiquement inerte ; les soudures en PP dans des configurations complexes avec une faible résistance à l'air.
- Évacuation des installations de transformation des aliments— L'air chaud, gras ou saturé d'eau provenant de fours et de cuisinières est évacué par un tuyau d'évacuation en PP qui résiste à la chaleur et est facile à désinfecter.
- Municipal and industrial wastewater treatment— Les couvercles de réservoirs libèrent du sulfure d'hydrogène et de l'air humide ; le PP résiste aux composés de soufre qui attaquent l'acier.
- Chambres propres à semi-conducteurs et à l'électronique — process exhaust must avoid metallic ion contamination, which PP naturally avoids compared with steel.
Dans chacun de ces cas, le facteur déclenchant est le même : un matériau qui conserve sa forme et résiste à la corrosion à la température de fonctionnement. Le polypropylène fournit cela à un niveau de coût moyen, et la ligne Faygo fournit le tuyau à une qualité constante qui permet à l'installateur de souder les joints en toute confiance. Pour les runs de tuyaux de grande diamètre, la plateforme à double vis de 12 à 575 millimètres couvre les tuyaux principaux, tandis que la ligne à une vis de 16 à 160 millimètres produit le conduit de branche qui relie les capots et les machines individuels au conduit principal.
Pipe wall thickness for flue and vent duty is usually selected from a standard dimension ratio, often referenced as SDR, which sets the wall as a fraction of the outside diameter. A lower SDR means a thicker, stiffer wall suited to larger diameters or where the duct carries pressure from a fan or where external loads apply; a higher SDR reduces material use for low-pressure gravity vents. Because the Faygo calibration and haul-off are synchronized, the line holds the chosen SDR consistently along the entire length, which matters for fume extraction where a uniform internal surface keeps airflow resistance predictable and prevents turbulent pockets that could drop corrosive condensate. The application team reviews the duct routing, fan pressure, and support spacing during plant design so the extruded wall thickness matches the mechanical demand rather than a generic default.
How to Select the Right Faygo Extrusion Line
Le choix commence par deux variables : le diamètre extérieur du tuyau que vous devez produire et la température maximale du gaz que le conduit rencontrera en service. Le tableau ci-dessous associe ces variables à la ligne Faygo et à l'extrudeur recommandés, de sorte qu'un acheteur puisse passer de la spécification du projet à la sélection de la machine sans deviner.
| Diamètre de la tuyauterie | Température maximale du gaz | Recommended PP Grade | Ligne d'extrusion Faygo recommandée | Extrudeur |
|---|---|---|---|---|
| 16 à 32 millimètres | Jusqu'à 95 degrés Celsius | PP-R ou PP-H | Ligne d'extrusion de tuyaux en PP-R/PE-RT | Single-screw 45 to 60 mm |
| 40 to 110 millimètress | Up to 100 degrees Celsius | PP-H. | Ligne d'extrusion de tuyaux en PP-R/PE-RT | Single-screw 60 to 75 mm |
| 110 à 160 millimètress | Up to 110 degrees Celsius | PP-H ou PP-GF 20 pour cent | Ligne d'extrusion de tuyaux en PP-R/PE-RT | Single-screw 90 mm |
| 160 to 400 millimeters | Up to 100 degrees Celsius | PP-H. | Ligne de production de tuyaux en PVC (twin-screw core) | Twin-screw 80/156 |
| 400 to 575 millimeters | Up to 80 degrés Celsius | PP-H. | Ligne de production de tuyaux en PVC (large) | Twin-screw 92/188 |
| Multi-material plant | Up to 90 degrees Celsius | PP and PVC mix | Ligne de production de tuyaux en PVC (65/132 core) | Twin-screw 65/132 |
The selection logic is simple to apply: pick the diameter band, confirm the gas temperature ceiling, then choose the grade and the matching Faygo extruder. A workshop whose flue never exceeds 100 degrees Celsius and needs branch duct up to 160 millimètress is fully served by the single-screw Ligne PP-R/PE-RT; a plant building large main trunk lines or mixing PP with PVC drainage should deploy the twin-screw core. Where sustained temperature exceeds 100 degrees Celsius, move to PP-GF and confirm the screw and barrel are configured for glass-fiber compounds before order confirmation.

Questions fréquemment posées
Quelle température peut supporter un tuyau d'évacuation des gaz de combustion en polypropylène ?
Un tuyau d'évacuation standard en PP-H ou en PP-R peut supporter des températures continues d'environ 100 degrés Celsius, tandis que les grades de polypropylène renforcés de fibres de verre étendent la température de déformation à environ 140 à 150 degrés Celsius. Des pics de 120 à 140 degrés Celsius sont tolérés par le polypropylène non rempli sans déformation permanente, ce qui couvre la plupart des applications de tuyaux d'évacuation et de ventilation des ateliers.
Pourquoi choisir le PP au lieu du PVC pour les canalisations d'évacuation des fumées et de ventilation des ateliers ?
PVC softens and begins to degrade near 60 degrés Celsius and releases hydrogen chloride gas above 80 to 100 degrees Celsius, so it is unsafe for hot exhaust. Polypropylene remains stable to about 100 degrees Celsius, resists acidic flue condensates, and is far lighter and easier to weld than steel, which corrodes in the same acidic environment.
Quelle ligne d'extrusion Faygo dois-je utiliser pour les tuyaux d'évacuation et de ventilation en polypropylène ?
For diameters from 16 à 160 millimètres the Ligne d'extrusion de tuyaux PP-R/PE-RT de Faygo with a single-screw barrier extruder is the right choice. For multi-material or larger diameter projects up to 575 millimeters, the Ligne de production de tuyaux en PVC Faygo with a parallel twin-screw core covers PVC, PP, and PE pipe production from one platform.
Quelle configuration de vis d'extrudeuse est la meilleure pour les tuyaux de polypropylène à haute température ?
Le polypropylène est mieux traité sur une extrudeuse à une seule vis équipée d'une vis de barrière (BM) et d'une section de mélange à un ratio L/D de 33 à 1. Cette géométrie offre un plastification uniforme, une température de fusion basse et une production stable, ce qui protège les composés en polypropylène sensibles à la chaleur utilisés dans les applications de tuyaux d'évacuation et de ventilation.
Comment Faygo garantit-il la fiabilité de la ligne d'extrusion avant la livraison ?
Chaque ligne d'extrusion de tuyaux Faygo est soumise à un test d'exploitation continue de 72 heures avant la livraison, avec un contrôle intelligent en boucle fermée de la température de fusion, du vide et de la synchronisation de l'évacuation. Les clients reçoivent également 500 pièces de rechange gratuites par an, des remplacements garantis et une assistance technique en ligne 24/7 après l'installation.
Can PP flue pipes handle acidic chemical plant exhaust?
Oui. Le polypropylène présente une excellente résistance à la plupart des acides, des alcalis et des condensats salins présents dans les évacuations des usines chimiques et les exhausteurs de galvanoplastie. À la différence de l'acier carboné, le PP ne corrode pas, de sorte qu'un tuyau d'évacuation en polypropylène conserve son épaisseur de paroi et son débit d'air pendant une longue durée de service sans revêtement protecteur.
Quelles normes s'appliquent au tuyau en polypropylène produit sur une ligne Faygo ?
PP pipe produced on Faygo lines can be validated against ISO 15874 and ISO 15494 for polypropylene piping systems, ASTM D4101 for PP material, and GB/T 18742 for Chinese hot and cold water polypropylene pipe systems. These standards define dimensions, heat resistance, and long-term hydrostatic strength for the finished duct.
Une configuration d'usine clé en main est-elle disponible pour la production de tuyaux d'évacuation en polypropylène ?
Oui. Faygo, en tant que fabrique Wanplas, propose des solutions clés en main personnalisées qui comprennent la conception de l'eau et de l'électricité, la planification de l'atelier en 3D, la formation des travailleurs, l'installation et la mise en service, ainsi que le soutien à l'extension de la capacité, afin que l'on puisse mettre en production de masse une nouvelle usine ou une usine modernisée avec un temps d'arrêt minimal.

Polypropylene, in PP-H, PP-R, or glass-fiber reinforced grades, delivers the temperature resistance and chemical inertness that flue and vent pipelines demand, and Faygo, une usine Wanplas with 22 years of pipe and profile extrusion experience, builds the lines that produce that pipe at industrial scale. The single-screw Ligne d'extrusion de tuyaux en PP-R/PE-RT covers 16 to 160 millimètres branch and main duct, while the parallel twin-screw Ligne de production de tuyaux en PVC extends coverage to 575 millimeters and multi-material plants, both running Certifié CE et ISO, 72-hour tested, intelligently controlled production.
For any workshop flue, fume extraction, ventilation duct, or chemical plant vent project, the selection method is direct: match the pipe diameter and gas temperature to the grade and the Faygo line shown in the selection table, confirm the screw and barrel are configured for the chosen PP compound, and rely on the Wanplas group USD 500 free parts per year policy plus open factory support for a low-risk investment. Send your pipe diameter range, target gas temperature, and daily output requirement to receive a tailored line configuration, arrange a factory audit, or schedule a sample trial run on a running Faygo extrusion line.
