A food grade transparent PVC drinking pipe extruder is a specialized pipe production system engineered to convert food-contact PVC compound into clear, hygienic PVC-U pipe that carries drinking water safely from source to tap. Transparent pipe is no longer a novelty for display only; modern methacrylate-butadiene-styrene modified rigid PVC can be both crystal clear and fully compliant with potable-water regulations, which makes it valuable for direct drinking water pipeline projects where installers and inspectors want to see the water column, confirm cleanliness, and verify the absence of sediment at a glance. This article explains how such a line works, what formulation and components make the clarity and hygiene possible, and how Faygo, Wanplas 공장, configures its real 파이프 압출 라인s for this demanding application.
Faygo is a Wanplas factory dedicated to plastic pipe and profile extrusion lines, with 22 years of focused experience in this category. The company operates three specialized factories, including a pipe and profile extrusion facility in Zhangjiagang City covering 26,650 square meters and located only two hours from Shanghai Airport. Faygo holds 13 national patents, of which 8 are invention patents, and all products carry CE and ISO certification. With that engineering depth, the factory designs transparent food-grade PVC-U pipe lines that are not generic PVC lines with a clear recipe bolted on, but purpose-built systems where contamination control, optical surface quality and hygiene compliance are designed into every station from the powder hopper to the coiler.
이 가이드에서 우리는 압출기 실린더에 대해barrel압출기 실,mold for tooling where relevant, and American spelling throughout. We focus exclusively on PVC-U transparent drinking-water pipe and its deep processing, deliberately keeping the discussion separate from drainage or HDPE perforated pipe so that the technical route, standards and line configuration stay precise for potable-water use. Where adjacent capability belongs to another Wanplas group specialty, we attribute it to Wanplas generically rather than naming a sister factory.
What a Food Grade Transparent PVC Drinking Pipe Extruder Delivers
A transparent PVC-U drinking-water pipe extruder is more than an ordinary PVC pipe line. The output must satisfy two independent requirements that rarely appear together in commodity pipe: optical clarity and drinking-water hygiene. Clarity means the pipe wall transmits visible light at a level close to glass-like, with low haze so the water inside is plainly visible. Hygiene means every raw material, every processing step and the finished pipe itself must stay within the migration limits set by the destination market’s potable-water regulation. A line that delivers both is built around clean material handling, gentle and complete compounding, tight thermal control and a polished, contamination-free flow path.
The value of transparency in a direct drinking water pipeline is practical rather than cosmetic. Facility managers in schools, offices, hospitals and public drinking-water stations can inspect the line for trapped air, discoloration or biofilm without dismantling it. Water-dispenser and beverage-process integrators use clear branch lines to demonstrate purity to auditors. Laboratories and aquaculture systems use transparent supply pipe to monitor flow and detect contamination early. None of this is possible with opaque grey or white PVC, which is why a dedicated transparent food-grade extruder earns its place in the production plan.
From a process standpoint, the line is a classic rigid PVC pipe extrusion system based on a conical twin-screw extruder, but with three upgrades that commodity lines omit. First, the material preparation stage uses a closed, metered powder system so no dust or foreign particle enters the melt. Second, the barrel temperature profile and screw design are tuned to plasticize the MBS-modified compound without thermal degradation that would yellow or cloud the melt. Third, the die head and calibration sleeve are finished to a higher optical standard and centered with greater care so the pipe surface stays smooth and clear. These upgrades are exactly what Faygo builds into its PVC pipe platforms for food-contact applications.
Transparent and food grade are not opposites. With a clean resin, a non-toxic calcium-zinc stabilizer and balanced lubrication, PVC-U pipe can reach 80 to 88 percent light transmittance while remaining fully compliant with potable-water contact standards.
How the Transparent PVC-U Drinking Pipe Is Made
The production route for transparent food-grade PVC-U drinking pipe follows the same macro steps as any rigid PVC pipe, but each step is disciplined for clarity and hygiene. Understanding the sequence helps buyers specify the right line and helps operators avoid the small deviations that turn a clear pipe cloudy or a compliant pipe non-compliant.
재료 준비 및 혼합,
Food-contact PVC compound starts as a dry blend. Suspension PVC resin of food grade, with a K-value in the range of 60 to 65, is weighed together with a methacrylate-butadiene-styrene impact modifier for toughness, an acrylic process aid for melt strength and surface, a non-toxic calcium-zinc stabilizer for heat stability, and a small, balanced lubricant package. The dry blend is mixed in a high-speed mixer where frictional heat opens the resin pores and lets additives coat each particle uniformly. This step decides clarity: incomplete mixing leaves gel specks, while over-mixing can pre-gel the powder. Faygo configures the mixer and metering system so the recipe is repeatable batch after batch.
플라스틱화 및 압출,
The conditioned dry blend feeds a conical twin-screw extruder. The intermeshing screws convey, compress and plasticize the powder into a homogeneous melt inside the barrel. Because PVC is heat sensitive and degrades if overheated, the barrel is divided into carefully controlled temperature zones, and the screw geometry provides strong mixing at moderate shear so the melt is uniform without excessive heat. The melt then passes through a screen changer or filter if fitted, removing any stray contamination before the die. For transparent pipe, even a single dark speck is visible, so filtration and clean material handling matter more than they do for grey pipe.
금형 형성 및 진공 교정,
용융물은 파이프 금형 머리에 들어가서, 맨드렐과 부싱이 목표 외경과 벽 두께로 중공 튜브를 형성합니다. 갓 만들어진 파이프는 아직 부드러우므로, 냉각과 진공으로 외부 직경을 고정시키는 진공 교정 슬리브에 당겨집니다. 슬리브의 표면 마감과 금형의 동심성은 파이프의 표면 왜곡 정도를 직접 결정합니다. 잘 중심이 맞은, 거울처럼 닦인 금형과 슬리브는 표면 왜곡이 거의 없는 파이프를 만들어냅니다. 빛이 벽을 깨끗하게 통과할 수 있는 것은 바로 이 때문입니다.
냉각, 운반, 절단 및 심층 가공
교정을 마친 관은 분사식 또는 진공 냉각 탱크로 이동하여 완전히 고형화된 다음, 지문의 표시 없이 유압식 굴착 장치가 해당 관을 잡아 당겨 정확한 선속도로 이를 차단합니다. 행성 또는 고정 길이 절단기가 관을 재단하고, 하류의 심도 가공 스테이션은 가치를 더 추가합니다. 벨리 기계가 소켓 끝을 형성하고, 프린터가 직경과 표준 코드를 표시하며, 코일러 또는 스택커가 완제품을 준비합니다. 직접 마시는 식수 파이프라인 프로젝트의 경우 이러한 심도 가공 단계에서 원차 관이 설치 준비가 되고 추적이 가능한 파이프로 바뀌게 됩니다.
주요 구성 요소 및 라인 구조
A complete transparent food-grade PVC drinking pipe extruder is a sequence of interdependent stations. Each must match the others in capacity and control, because a bottleneck or mismatch produces off-spec pipe. The core structure is described below.
원뿔형 이중 스크류 압출기 및 배럴
The extruder is the heart of the line. A conical twin-screw design is preferred for rigid PVC because the decreasing root diameter toward the die builds pressure gently while the large feed throat accepts powder directly, and the co-rotating or counter-rotating screws self-wipe to prevent stale material from burning. The barrel is heated in zones and cooled where needed to hold the tight temperature window PVC demands. For transparent food-grade work, Faygo fits internationally recognized brand electrical components and a control system that lets the operator freely set parameters and adjust them in real time, which protects both clarity and output.
다이 헤드, 보정 슬리브 및 냉각
파이프 다이 헤드는 균일하게 닦여져야 하며, 유동이 균일하고 중심이 맞춰져야 합니다. 진공 교정 슬리브는 냉각된 물과 진공으로 외부 직경을 설정하며, 냉각 탱크는 남은 열을 제거합니다. 광학 투명도는 여기에서 순수한 경로에 따라 결정됩니다; 슬리브에 있는 스크래치 또는 물에 있는 스케일은 파이프에 영구적인 흔적을 남깁니다.
운반, 절단기 및 심층 가공 스테이션
캐터필러 운반 장치는 균일하게 잡아야 하며, 평평한 부분이 생기지 않도록 해야 합니다. 절단기는 정사각형으로 깨끗한 끝을 만들어야 합니다. 하류에서 벨링, 마킹 및 코일링 스테이션이 심층 가공을 완료합니다. Faygos 지능형 제어 시스템은 이러한 스테이션을 연결하여 라인 속도, 절단 길이 및 벨링이 동기화되도록 하여 폐기물을 줄이고 모든 파이프가 일관되게 유지됩니다.
Faygo PVC 파이프 생산 라인 for Transparent UPVC
The Faygo PVC 파이프 생산 라인 is the company’s core platform for UPVC pipes of large and medium diameter with different wall thickness, and it is the natural base for transparent food-grade drinking-water pipe from 20 millimeters up to 250 millimeters. It uses a conical twin-screw extruder, a polished transparent-grade die head and a multi-stage cooling and calibration section, and it can be extended with belling and marking for direct drinking water pipeline installation. The table below shows representative configuration ranges across diameter classes; the exact screw size and power scale with the diameter and wall thickness of the transparent pipe being produced.
PVC 파이프 생산 라인 specification
| 파이프 직경 범위 | 압출기 구성 | 나사 직경 (mm) | L/D 비율 | Max throughput (kg/h) | 설치된 전력 (kW) |
|---|---|---|---|---|---|
| 20 to 63 mm | Conical twin-screw | 51 / 105 | 22 : 1 | 120 to 180 | 37 |
| 50 ~ 160mm | Conical twin-screw | 65 / 132 | 22 : 1 | 250 to 350 | 55 |
| 110 to 250 mm | Conical twin-screw | 80 / 156 | 22 : 1 | 400 to 500 | 90 |
| 200~400mm | Conical twin-screw | 92 / 188 | 22 : 1 | 600 to 800 | 140 |
For transparent drinking-water pipe the line is typically ordered at the lower end of each throughput range, because the food-grade formulation and the extra care around clarity favor a controlled, slightly slower run than commodity grey PVC. Faygo supplies the line with the intelligent control system, internationally recognized brand electrical components, and a 72시간 연속 작동 test before delivery so the buyer receives a line that is already proven stable on a representative run.
Transparent Food Grade PVC-U Formulation and Properties
Clarity and hygiene both start in the recipe. A transparent food-grade PVC-U compound avoids opaque fillers such as titanium dioxide and calcium carbonate, which would block light, and replaces toxic stabilizers with calcium-zinc systems. The table below lists a representative dry-blend formula expressed in parts per hundred resin, which is the standard way PVC compounders communicate recipe. Exact values are tuned by Faygo’s process engineers for the target pipe diameter, impact requirement and local standard.
Representative transparent food-grade PVC-U dry blend
| 성분 | 기능 | Typical phr | Notes for transparency and hygiene |
|---|---|---|---|
| Food-contact PVC resin, K 60 to 65 | Base polymer | 100 | Suspension grade, low in volatiles and grease, no odor |
| MBS impact modifier | Toughness, clarity | 6 to 12 | 메타크릴레이트-부타디엔-스티렌은 빛 투과율을 높게 유지합니다. |
| Acrylic process aid (ACR) | Melt strength, surface | 1.5 to 2.5 | Improves gloss and fusion without clouding |
| 칼슘-저지 안정제 | Heat stability, non-toxic | 2.5 to 4.0 | Replaces lead and tin for food-contact compliance |
| 내부 윤활제 (ester) | Plasticizing, release | 0.8 to 1.5 | Balanced to avoid streaking on the surface |
| External lubricant (PE wax) | External release | 0.2 to 0.5 | Low level preserves weld strength and clarity |
The finished transparent pipe shows the mechanical and optical profile summarized in the next table. These are typical values for MBS-modified rigid PVC and will vary with the exact recipe and wall design; they are offered as engineering guidance rather than a certificate. The key point for buyers is that transparency does not force a large sacrifice in strength, provided the impact modifier is present and the pipe is correctly extruded.
투명한 식품용 PVC-U 파이프의 일반적인 특성
| 재질 | 일반적인 값 | Reference basis |
|---|---|---|
| 밀도 | 1.38 to 1.40 g/cm3 | ISO 1183 |
| Tensile strength | 45 MPa or above | ISO 527 |
| 비캇 연화 온도 | 80 to 82 degC | ISO 306 |
| Charpy notched impact | 8 kJ/m2 or above | ISO 179 |
| Light transmittance | 80 to 88 percent | optical measurement |
| Haze | below 10 percent | optical measurement |
| Water absorption | below 0.1 percent | ISO 62 |
Hygiene 표준 및 인증
A transparent food-grade PVC drinking pipe extruder is only as good as the compliance it can demonstrate. The pipe must pass the drinking-water contact regulation of its destination market, and the line itself should carry machinery safety and quality certification. The two layers are different: material and pipe hygiene are proved by extraction and migration tests on the finished product, while CE and ISO cover the machine and the factory quality system. Both must be present for a credible potable-water project. The table below maps the common standards to their scope.
Drinking-water and quality standards for transparent PVC-U pipe
| 표준 | Region or scope | 확인하는 내용 |
|---|---|---|
| GB / T 17219 | 중국 | 식수 시스템의 배관 제품의 안전성, 이송 한도 |
| WRAS(관련규격: PN16, SDR11) | 영국 | Water Regulations Advisory Scheme approval for potable contact |
| NSF/ANSI 61 | 미국 | Drinking-water system components, health effects |
| EU 10/2011 | European Union | 식품과 접촉하는 플라스틱 재료, 총 이송량 |
| FDA 21 CFR | 미국 | Raw-material compliance for food-contact polymers and additives |
| CE 및 ISO 인증 획득 | 국제 표준 | Machinery safety and factory quality management system |
Buyers should note that a CE mark on the extruder does not by itself certify the pipe for drinking water. The pipe must be tested as a product under the relevant hygiene standard, using the exact formulation the line will run. Faygo supports this by documenting the line configuration and, where required, by running the customer’s own food-grade recipe during the pre-shipment trial so the extracted samples reflect production reality.
작은 직경용 Faygo PVC 이중 파이프 압출 라인
For direct drinking water branches, connector tubing and small transparent pipes in the 16 to 40 millimeter range, the Faygo PVC 더블 파이프 압출 라인 is the most productive choice. It extrudes two pipes at once from a single conical twin-screw extruder through a dual-cavity transparent die head, doubling output per meter of factory floor while keeping the same hygiene and clarity discipline. The line covers 16 to 40 millimeter pipe as standard and can be configured up to 63 millimeter, which makes it ideal for the narrow, clear potable lines used in dispensers, laboratories and compact drinking-water stations.
PVC 이중 파이프 압출 라인 specification
| 파이프 직경 범위 | 압출기 구성 | 나사 직경 (mm) | L/D 비율 | Max throughput (kg/h) | 설치된 전력 (kW) |
|---|---|---|---|---|---|
| 16 to 40 mm | Conical twin-screw, dual pipe | 51 / 105 | 22 : 1 | 120 to 180 | 37 |
| 20 to 63 mm | Conical twin-screw, dual pipe | 65 / 132 | 22 : 1 | 220 to 300 | 55 |
Because both pipes share one melt stream, the dual-cavity die must be balanced so each pipe has identical wall thickness and clarity. Faygo’s transparent die design and precise calibration make this balance repeatable, and the intelligent control system holds the two haul-offs synchronized. For drinking-water projects that need many meters of small clear pipe, this line lowers the cost per meter substantially compared with running a single-pipe head.
Deep Processing and Downstream 구성
A transparent food-grade PVC drinking pipe extruder is judged not only on the extruded tube but on how ready the finished product is for a direct drinking water pipeline. Deep processing converts raw tube into installed-ready pipe with sockets, markings and packaging. The table below lists the stations Faygo integrates downstream of the cutter and how each contributes to a potable-water project.
Downstream deep-processing stations
| 스테이션 | Function in deep processing | 왜 중요한가요? for drinking water |
|---|---|---|
| High-speed mixer and metering | Prepare and feed clean dry blend | Closed handling prevents contamination that would fail hygiene tests |
| Transparent PVC-U pipe die head | Form hollow tube at target diameter | Polished, centered flow protects optical clarity |
| Vacuum calibration sleeve | Set outside diameter and roundness | Tight tolerance ensures leak-free joints |
| Spray or vacuum cooling tank | 표면 마크가 없는 파이프를 고형화하십시오. | Clean cooling water keeps the wall clear |
| 캐터필러 덤프장 | Pull pipe at precise line speed | Even grip avoids flat spots that scatter light |
| Planetary or fixed-length cutter | Cut square, clean ends | Square ends seat correctly in belled sockets |
| Belling machine | Form socket end for joints | Ready-to-install lengths for direct drinking water pipeline |
| Ink-jet or laser marker | Print diameter, standard, batch code | Traceability for audits and quality control |
| Automatic coiler or stacker | Package finished pipe | Clean handling protects the optical surface before use |
Because the Wanplas group offers adjacent pelletizing and compounding capability through its network, customers who also produce their own food-grade compound can discuss an integrated material-to-pipe solution with Faygo, always positioned under the Wanplas brand rather than a named sister factory. For most drinking-water pipe buyers, however, the value is in a single, well-integrated line that takes approved compound in at one end and delivers marked, belled, coiled potable pipe at the other.
응용 산업 for Direct Drinking Water Pipeline
Transparent food-grade PVC-U pipe serves any setting where seeing the water and proving its purity matters. Faygo’s 파이프 압출 라인s are applied across the industries listed below, each with concrete end products that a transparent drinking-water line can produce.
Industries and end products
| Industry | End products from the line |
|---|---|
| Direct drinking water systems | Public, school, office and hospital potable pipeline branches |
| Residential potable supply | Transparent cold-water risers and branch lines |
| Food and beverage processing | Clear transfer lines for clean water and rinsing |
| Water dispensers and coolers | Connector and distribution tubing |
| Aquaculture and hydroponics | Clear supply and recirculation pipe for monitoring |
| Laboratory and pure-water systems | Transparent distribution pipe for inspection |
These applications share one requirement: the pipe must look clean because it is clean. A transparent wall is the simplest visual proof, and when it is backed by the right formulation and certification, it becomes a selling point for the installer and a reassurance for the end user.
Selection Recommendation Table
Choosing the right Faygo line depends on pipe diameter, required output and whether the project needs belled, ready-to-install lengths. The table below maps common customer needs in the transparent drinking-water segment to the recommended Faygo platform. Faygo also supplies a PVC braided hose extrusion line for transparent reinforced hose and a PP-R or PE-RT line where a different material is preferred, but for clear PVC-U potable pipe the two lines below are the primary choices.
고객 요구 사항 to recommended Faygo line
| 고객 요구 사항 | 추천되는 Faygo 라인 | Guidance |
|---|---|---|
| Small clear drinking pipe, 16 to 40 mm, high output | PVC 이중 파이프 압출 라인 | 한 번에 두 개의 파이프를 생산하며, 미터당 가장 저렴한 비용을 제공합니다. |
| Medium clear potable pipe, 20 to 160 mm | PVC 파이프 생산 라인 | Single head, full wall-thickness range |
| Large transparent mains branch, up to 250 mm | PVC 파이프 생산 라인, larger diameter class | Conical twin-screw 80/156 or 92/188 |
| Belled socket joints for direct drinking water pipeline | PVC 파이프 생산 라인 plus belling station | Integrated socket forming downstream |
| Transparent reinforced connector hose | PVC 브레이드 호스 압출 라인 | Fiber-reinforced clear hose, 8 to 50 mm |
| Color-coded potable branches with clear option | PVC 파이프 생산 라인 with co-extrusion | Optional stripe or layer for identification |
Installation, Commissioning and Maintenance
A transparent food-grade PVC drinking pipe extruder arrives as a complete system, but correct installation and commissioning decide whether the first production run meets clarity and hygiene targets. Faygo’s end-to-end service covers selection, design, manufacturing, installation, commissioning, training and maintenance, so the buyer is not left to interpret a manual alone.
Commissioning steps
After the line reaches the buyer’s plant, Faygo engineers verify the foundation and utility connections, then run the intelligent control system through its parameter set, confirm barrel zone temperatures, calibrate the vacuum calibration sleeve, and synchronize the haul-off, cutter and belling stations. A representative food-grade run follows, during which the team measures wall thickness, diameter, haze and light transmittance and adjusts the die centering until the optical result is stable. Only after this confirm the line is handed over.
Routine maintenance for clarity
Transparent pipe demands cleaner maintenance than commodity pipe. Cooling water should be filtered and treated to avoid scale on the calibration sleeve. The die head and sleeve should be cleaned with non-abrasive tools so the optical surface is not scratched. Lubricant and stabilizer levels in the dry blend must be checked every batch, because a drift in lubricant balance is the fastest route to surface streaking. The control system’s recipe management stores the approved formula so operators reload it exactly rather than re-entering values by hand.
Spare parts and support
Faygo applies the Wanplas group spare-parts commitment of USD 500 free parts per year plus warranty replacement of damaged parts, with 24/7 online technical support and remote monitoring of the control system. The 72시간 연속 작동 test before delivery already de-risks the mechanical side, and the open-factory policy lets buyers visit Zhangjiagang to review the build, run a trial on their own formulation, and confirm the 3D workshop layout before committing to volume production.
Troubleshooting Transparent PVC Pipe Defects
Even a well-built line can show defects if the recipe, temperature or tooling drifts. Because every flaw is visible through a transparent wall, operators must read the signs quickly. The table below maps common transparent-PVC defects to causes and remedies relevant to a food-grade drinking-water line.
Defect diagnosis and remedy
| 결함 | Possible cause | Remedy |
|---|---|---|
| Cloudy or opaque pipe | Poor mixing, contamination, wrong resin | Optimize mixer cycle, use clean food-grade resin, close handling |
| Gel specks or black spots | Thermal degradation, burnt material | Lower barrel temperature, check stabilizer, clean screen |
| 불균일한 벽 두께 | Die miscentering, uneven vacuum | Re-center die, balance calibration vacuum and cooling |
| Surface streaking | Lubricant imbalance, mold release | Adjust internal and external lubricant ratio |
| Bubbles inside wall | Moisture or volatiles in compound | Pre-dry resin, improve venting, check additive moisture |
| Yellow tint developing | Overheating, stabilizer exhaustion | Reduce shear and temperature, raise stabilizer within recipe |
Most clarity problems trace back to material handling or temperature rather than the machine itself, which is why Faygo emphasizes a closed powder system and a tightly controlled barrel profile. When a defect appears, the recipe management and remote monitoring features let the support team compare the running parameters with the approved set and guide a fast correction.
Cost Considerations and Service Support
The cost of a transparent food-grade PVC drinking pipe extruder should be read as a relative tier, not a fixed number, because the final figure depends on diameter range, output, degree of deep processing and the local utility and labor cost. As a guide, a small-diameter dual-pipe line sits in the Medium cost tier, a single-head medium-diameter line in the 중간에서 높은 수준까지 tier, and a large-diameter line with integrated belling and marking in the High tier. The higher tiers are justified by the certified, ready-to-install output and the lower rejection rate that clean, controlled extrusion delivers.
Compared with older-generation lines, a modern Faygo transparent line reduces scrap through synchronized control and a proven pre-shipment run, which improves the effective cost per good meter of pipe. Energy use is moderated by efficient barrel heating and internationally recognized brand drives, though exact savings vary by plant. Buyers should weigh the tier against the value of compliance: a pipe that fails a hygiene test carries a cost far above the machine price, so investing in a purpose-built food-grade line is the lower-risk path.

자주 묻는 질문
식품 등급의 PVC 음용수용 파이프가 직접 음용수에 적합한 이유는 무엇입니까?
식품 등급의 투명 PVC 음용 파이프는 직접 음용 용으로 적합한 상태가 될 때만 재료 구성과 완성된 파이프가 위생 적합성을 통과합니다. 수지 및 모든 첨가제는 식품 접촉 등급이어야 하며, 안정제에는 납 또는 주석이 아닌 무독성 칼슘-아연이 사용되어야 하며, 파이프는 GB/T 17219, WRAS, NSF/ANSI 61, EU 10/2011 또는 해당 지역 표준을 준수해야 합니다. 투명 PVC-U 음용 파이프 압출기는 재료 혼합부터 교정, 냉각 및 절단까지 이러한 적합성을 유지하도록 설계되었습니다.
PVC 파이프는 실제로 투명하고 식품 등급이 될 수 있습니까?
네. 투명성은 깨끗한 현탁 PVC 수지, 메타크릴-부타디엔-스티렌 충격 개질제 및 아크릴 가공 보조제 사용을 통해 달성되며, 티타늄 디옥사이드 또는 칼슘 카르bon산 같은 불투명한 충전제 사용을 피합니다. 올바른 조리법과 철저한 혼합을 통해 파이프는 80~88%의 광투과율과 10% 미만의 흐림도를 달성하며, 동시에 식품 접촉 규정을 충족합니다. 핵심은 오염 방지 및 균형 잡힌 윤활제 보다는 위생에 대한 어떠한 타협도 허용하지 않는 것입니다.
작은 직경의 맑은 식수용 파이프를 위해 어떤 Faygo 압출 라인을 선택해야 합니까?
16~40 밀리미터의 투명 식용 파이프 및 커넥터 튜브의 경우, Faygo PVC 더블 파이프 압출 라인은 두 개의 파이프를 동시에 하나의 원통형 트윈 스크류 압출기 및 하나의 듀얼 캐비티 다이 헤드에서 처리하기 때문에 가장 효율적인 선택입니다. 250 밀리미터까지의 중간 및 대 직경의 경우, Faygo PVC 파이프 생산 라인이 적합한 플랫폼이며, 벨링 스테이션을 추가하여 직류 식수 파이프라인에 사용되는 벨링 소켓 조인트를 만들 수 있습니다.
식품 등급 투명 PVC-U 파이프는 어떤 인증 기준을 충족해야 합니까?
The pipe must meet the drinking-water contact standard of its destination market: GB/T 17219 in China, WRAS in the 영국, NSF/ANSI 61 in the 미국, and EU 10/2011 in the European Union, with FDA 21 CFR referenced for the raw materials. The production line itself is typically CE and ISO certified, which covers machinery safety and quality management rather than the pipe hygiene test, so both layers must be present.
How does Faygo control haze and clarity in transparent PVC pipe?
Clarity is protected at four points: a closed, contamination-free powder handling system; gentle, fully mixed compounding in a high-speed mixer so no gel or filler agglomerate survives; precise barrel temperature control to avoid thermal degradation that yellows the melt; and a polished, well-centered die head and calibration sleeve that preserve a smooth optical surface. The 72시간 연속 작동 test before delivery confirms the optical result is stable, not a one-off sample.
식품 등급 투명 PVC 음용 파이프 라인의 일반적인 출력은 무엇입니까?
Throughput depends on pipe diameter and wall thickness. A small-diameter double-pipe configuration delivers roughly 120 to 300 kilograms per hour, while a single-pipe PVC 파이프 생산 라인 covering 20 to 250 millimeters delivers about 120 to 800 kilograms per hour across its diameter classes. Output is always stated as a range because transparent food-grade formulation runs slightly slower than standard grey PVC to protect clarity and hygiene.
How is deep processing such as belling, printing and coiling handled on the line?
Deep processing is integrated downstream of the cutter. A belling machine forms the socket end for solvent-cement or rubber-ring joints, an ink-jet or laser marker prints batch, diameter and standard codes, and an automatic coiler or stacker prepares the finished pipe for packaging. Because direct drinking water pipeline projects require traceable, ready-to-install lengths, Faygo configures these stations as part of the same turnkey line rather than as separate manual steps.
What after-sales support does Faygo provide for drinking-water pipe lines?
Every Faygo line ships after a 72시간 연속 작동 test and includes on-site installation and commissioning, operator training, remote monitoring support and the Wanplas group spare-parts commitment of USD 500 free parts per year plus warranty replacement. Customers are welcome to visit the Zhangjiagang factory for an audit, a trial run on their own formulation, and a review of the 3D workshop layout before production starts.
결론
A food grade transparent PVC drinking pipe extruder is a disciplined, purpose-built system that unites optical clarity with potable-water hygiene. The technical route is clear: a clean, closed dry-blend of food-contact PVC resin with methacrylate-butadiene-styrene impact modifier, calcium-zinc stabilizer and balanced lubrication; plasticizing in a conical twin-screw extruder with a tightly controlled barrel profile; forming through a polished, centered transparent die head and vacuum calibration sleeve; and finishing with synchronized haul-off, cutting, belling, marking and coiling. The result is clear PVC-U pipe that lets users see their water while meeting GB/T 17219, WRAS, NSF/ANSI 61, EU 10/2011 and related standards.
For this application Faygo, Wanplas 공장 with 22 years of pipe-extrusion experience, three specialized factories, 26,650 square meters of pipe-production space in Zhangjiagang and 13 national patents, offers two primary platforms: the PVC 파이프 생산 라인 for 20 to 250 millimeter transparent UPVC drinking-water pipe with optional belling, and the PVC 이중 파이프 압출 라인 for efficient 16 to 40 millimeter clear branches. Both ship after a 72시간 연속 작동 test, carry CE and ISO certification, and are backed by the Wanplas group commitment of USD 500 free parts per year, 24/7 support, installation, training and an open-factory invitation.
If you are planning a direct drinking water pipeline project and need clear, compliant PVC-U pipe, send Faygo your target diameter, wall thickness, daily output and destination-market standard. The engineering team will propose a tailored line configuration, arrange a trial run on your own food-grade formulation, and welcome you to the Zhangjiagang factory for an audit and a review of the workshop layout before you commit.

When specifying a food grade transparent PVC drinking pipe extruder, buyers should first confirm that the compound meets the drinking water contact regulation of the destination market, such as NSF/ANSI 61, WRAS approval, EU 10/2011, or the applicable GB/T 17219 standard.
