Introduction
Faygo, Wanplas 공장, has spent 22 years building specialized pipe and profile extrusion lines, and the two color marked HDPE water 파이프 압출 라인 is one of the most requested configurations for municipal water utilities that need fast, unmistakable pipeline identification on the construction site. Municipal networks are no longer simple single-pipe corridors; modern water districts run potable water, recycled water, fire-fighting water, and district heating in parallel trenches, and a pipe that looks identical at a glance becomes a serious risk during tie-ins, repairs, and asset audits. A two color marked HDPE pipe keeps the base resin color of the pipe body while laying a contrasting colored stripe along the length, so crews can identify the service class without measuring, without opening, and without consulting drawings buried in a tablet that may be out of battery.
This article explains how a two color marked HDPE water 파이프 압출 라인 works, why HDPE is the material of choice for municipal water supply, what extruder and downstream specifications matter, and how the stripe color system supports construction management from the factory floor to the trench. We walk through Faygo’s real pipe extrusion configurations, their output ranges, the color-code mapping utilities use, and the selection logic that matches a project’s diameter and volume requirement to the correct line model. Whether you run a pipe plant serving a city water bureau or you are specifying equipment for a new extrusion workshop, the guidance below is written to be technically credible and commercially useful.
The primary keyword for this piece is “two color marked HDPE water 파이프 압출 라인,” and it appears in the title, this opening section, several headings, and the conclusion. Faygo designs these lines as part of its broader pipe extrusion program that covers PE, PVC, and PP materials in diameters from 12 mm to 575 mm with wall thickness up to 6.5 mm, serving water supply, drainage, gas, communication, and agricultural irrigation. As a Wanplas factory, Faygo shares the group’s quality standards, CE and ISO certification discipline, and the Wanplas service promise that includes USD 500 free parts every year for supported lines.
What Is a Two Color Marked HDPE Water 파이프 압출 라인
A two color marked HDPE water 파이프 압출 라인 is a complete continuous production system that converts HDPE resin and additives into a finished, pressure-rated polyethylene pipe that carries one or more longitudinal colored stripes for identification. The “two color” descriptor does not mean the pipe is bicolored through its wall; it means the pipe body holds one base color while a second color is co-extruded as a surface stripe, typically four stripes at 90-degree spacing or one to two stripes for single-service marking. The result is a standard PE pipe that meets the same mechanical and hydrostatic requirements as a plain pipe, plus a permanent visual key that survives decades of burial.
Core line components from raw material to pipe
The production sequence begins with a gravimetric or volumetric dosing and mixing station where HDPE natural pellet, masterbatch for the base color, and a separate masterbatch for the stripe color are blended at controlled ratios. The blended material feeds a single-screw extruder fitted with a barrier-type screw optimized for polyethylene. Melt passes through a screen changer and a melt pump in higher-output configurations, then reaches the pipe die head. The die head integrates a dedicated small co-extrusion feeder for the stripe, so the stripe is formed in the same pass as the pipe without a secondary station.
After the die, the extrudate enters a vacuum calibration sleeve that fixes the outside diameter, followed by spray cooling tanks that set the wall. A haul-off (take-off) unit with rubber-block caterpillars pulls the pipe at a steady linear speed, a planetary or fly-knife cutter cuts it to length, and a tilt-down rack or automatic stacker collects the finished pipe. Throughout the line, a PLC with HMI touch screen governs temperatures, haul-off speed, and stripe ratio so that pipe dimensions stay inside tolerance.
How it differs from a plain HDPE pipe line
Compared with a conventional single-color HDPE line, the two color version adds three engineering elements: a second small extruder or a co-extrusion adapter for the stripe melt, a modified die head with stripe distribution channels, and a closed-loop control that holds the stripe width and position stable at varying line speeds. The incremental machinery cost on a normalized cost index of 100 sits at a Premium level of roughly 8 to 12 percent above a single-color line of equal diameter, but the payback arrives through reduced on-site misidentification, fewer wrong-service connections, and easier inventory control at the plant. In lifecycle terms the marking function carries a Low recurring cost because the stripe material is only a thin surface layer and the masterbatch consumption is a small fraction of total resin use.
Two-Color Stripe Marking Technology and 구성
The stripe is produced by co-extrusion, which fuses the marking layer to the pipe surface in the same thermal window as the base pipe, so the stripe cannot delaminate the way a painted or taped mark would. This is the central reason municipal utilities prefer extruded stripe marking over surface printing for buried infrastructure that must stay legible for fifty years. The configuration choices below determine how many stripes, how wide, and how reliably the mark holds.
The co-extrusion stripe principle
In a typical four-stripe head, the base extruder delivers the bulk melt to an annular die, while a smaller stripe extruder or side feeder injects colored melt into four equally spaced channels just before the die land. Because both melts share the same PE chemistry, they weld at the interface without an adhesive. Vacuum calibration then locks the stripe geometry onto the outside diameter. The stripe width is usually set between 8 mm and 25 mm depending on pipe diameter, and the position error is held within a few degrees by the die’s indexed channels.
Typical two-color stripe configuration parameters
| 매개변수 | 표준 구성 | Options for Municipal ID | 엔지니어링 노트 |
|---|---|---|---|
| Number of stripes | 4 stripes at 90° | 1, 2, or 4 stripes | Four stripes keep the mark visible from any rolling angle in the trench |
| 스트라이프 폭 | 12 mm | 8 mm to 25 mm | Wider stripe improves readability for large-diameter pipes |
| Stripe color source | Dedicated PE masterbatch | Blue, green, red, yellow, orange | 매장 및 노출에 적합한 UV 안정성이 필요합니다. |
| Base pipe color | Black (carbon black UV protection) | Black, blue, or natural | Black base with blue stripe is common for potable water |
| 스트라이프 압출기 | Small single-screw, 25 to 45 mm | Co-extrusion adapter option | Output matched to stripe area, not full pipe output |
| Stripe thickness | 0.3 mm to 0.6 mm | Adjustable via die land | Kept thin to limit masterbatch cost |
| Position tolerance | ±3° around axis | Tightened by indexed die | Prevents stripe drift at high haul-off speed |

Why HDPE for Municipal Water Supply Pipelines
HDPE, or high-density polyethylene, has become the default material for municipal water mains in many regions because it combines corrosion immunity, flexibility, and a long, leak-free service life. Unlike metallic pipe, HDPE does not rust, does not support bacterial growth on the inner wall, and tolerates ground movement without brittle fracture. These properties matter for construction management because a pipe that survives settlement and vibration reduces emergency excavation and rework.
Material properties that drive specification
수도 공급용 PE 파이프 are graded by the material designation, with PE80 and PE100 being the common municipal classes. PE100 offers higher minimum required strength, allowing thinner walls at the same pressure and therefore lower material mass per meter. HDPE also shows a low friction coefficient inside the bore, which preserves hydraulic capacity over decades because scaling and tuberculation do not occur the way they do in aged iron mains. The material is fully weldable by butt fusion and electrofusion, enabling joint-free continuous runs that eliminate the most common leak path found in flanged metallic systems.
Pipe specification by diameter range
| DN Range (mm) | Typical SDR / PN | Wall Thickness (mm) | Common Municipal Use | Marking Recommendation |
|---|---|---|---|---|
| DN 20 to DN 63 | SDR 11/PN 16 | 2.0 to 5.8 | Building connection, branch service | 파란색 기본 또는 검은색과 파란색 스트라이프 |
| DN 75 to DN 160 | SDR 11/PN 16 | 6.8 to 14.6 | Distribution mains, district branches | 검은색과 파란색 스트라이프, 1~4개의 스트라이프 |
| DN 200 to DN 315 | SDR 17 / PN 10 | 11.9 to 18.7 | Trunk distribution, recycled water | Black with dedicated color stripe |
| DN 355 to DN 500 | SDR 17 / PN 10 | 21.1 to 29.7 | Transmission mains, large districts | Multi-stripe coding for service class |
| DN 560 to DN 575 | SDR 21 / PN 8 | 26.7 to 27.4 | High-volume trunk, plant yard lines | 4 스트라이프 신원 시스템 |
Standards and certification context
Municipal HDPE water pipe is specified against international and national standards such as ISO 4427 for polyethylene pipes, ISO 9080 for the extrapolation of hydrostatic strength, and regional standards including EN 12201 in Europe and GB/T 13663 in China. Pressure classes are expressed as PN ratings tied to the standard dimension ratio, or SDR. Each Faygo pipe line is built so the calibration sleeve, haul-off, and cutter can hold the diameter and wall tolerances required by these standards, and the factory’s products are CE and ISO certified, which supports export and utility qualification processes.
Faygo Extruder 사양s for HDPE Pipe Lines
The heart of any HDPE pipe line is the single-screw extruder. For polyethylene, a barrier screw with a high L/D ratio delivers the homogenous melt and stable pressure needed for dimensionally tight pipe. Faygo configures extruders across the diameter range so that a small line for DN 20 to 63 uses a 65 mm screw, while a large trunk line for DN 500 uses a 150 mm screw. The table below maps typical extruder sizes to pipe diameter coverage.
라인 등급별 익스트루더 사양
| 압출기 모델 | Screw Diameter (mm) | L/D 비율 | 드라이브 파워 (kW) | Max Pipe Output (kg/h) | Coverage (DN) |
|---|---|---|---|---|---|
| SJ-65 | 65 | 33:1 | 37 to 45 | 180 to 220 | DN 20 to DN 63 |
| SJ-90 | 90 | 33:1 | 75에서 90 | 320 to 400 | DN 75 to DN 160 |
| SJ-120 | 120 | 33:1 | 132에서 160 | 550 to 700 | DN 200 to DN 315 |
| SJ-150 | 150 | 33:1 | 200 to 250 | 800 to 1000 | DN 355 to DN 575 |
Screw, barrel, and drive details
The barrier screw design separates solids conveying from melting, which lowers melt temperature and reduces degradation risk for heat-sensitive masterbatch in the stripe. The barrel uses bimetallic lining for wear resistance against filled compounds, and the feed zone is grooved in higher-output models to raise throughput. The drive is a vector inverter-fed AC motor paired with a hardened gearbox sized for continuous duty. On the largest lines, a melt pump is added between extruder and die to flatten pressure pulsation, which directly improves wall thickness uniformity and therefore reduces resin over-consumption. Intelligent control lets operators set target diameters and wall thickness once, then the system holds them with real-time adjustment.

Production Output and Capacity Planning
Output planning turns a project’s annual pipe demand into the correct line count and shift model. Because HDPE pipe is sold by length and pressure class, the practical planning unit is kilograms per hour of homogeneous resin converted into meters of finished pipe at a target SDR. The table below estimates finished-pipe meters per hour for representative diameters at standard wall, using the extruder outputs from the previous section. These are indicative figures; final meters depend on SDR, masterbatch ratio, and cooling water temperature.
Output and length planning by diameter
| 모델 | DN | Output (kg/h) | Approx. m/h at SDR 11 | 8h Shift (m) | 비용 지수 수준 |
|---|---|---|---|---|---|
| HDPE-TC63 | 63 | 200 | 230 | 1840 | 중간 |
| HDPE-TC160 | 160 | 380 | 95 | 760 | 중간 |
| HDPE-TC315 | 315 | 650 | 38 | 304 | 높은 수준 |
| HDPE-TC500 | 500 | 950 | 16 | 128 | 매우 높은 등급 |
Balancing extruder, cooling, and haul-off
The most common capacity bottleneck is not the extruder but the cooling length. Large-diameter thick-wall pipe needs long spray tanks to set the wall before the cutter, so a plant expecting high trunk-pipe volume should budget more floor space for cooling rather than a bigger extruder. Faygo’s turnkey layout service models this balance in a 3D workshop design so the line speed is not throttled by an undersized cooling section. On a normalized cost index of 100, extending the cooling line raises the footprint cost at a Low to Medium incremental rate while protecting the High-value output of the extruder investment.
Color-Code Standard Mapping for Pipeline Identification
The stripe color is only useful if it maps to a shared, documented convention that field crews and asset managers both understand. While regional utilities set their own codes, a widely used municipal mapping aligns stripe color to service type. The table below shows a representative mapping that a water bureau can adopt; the extrusion line simply reproduces the chosen colors as co-extruded stripes, so the pipe arrives pre-coded from the factory.
Representative color-code mapping
| 스트라이프 색상 | Service Class | Typical Use | Base Pipe Color | Identification Benefit |
|---|---|---|---|---|
| Blue | 음용수 | Drinking water mains | Black | Universal potable symbol |
| Green | Reclaimed / recycled water | Irrigation, industrial reuse | Black | Prevents cross-connection |
| Red | Fire-fighting water | Hydrant supply loops | Black | Fast emergency identification |
| Yellow | Gas (separate corridor) | Where co-laid by one contractor | Black | Excavation safety cue |
| Orange | Communication conduit | Telecom duct in shared trench | Black | Separates utility types |
| Purple | Recycled non-potable | Some regional codes | Black | Distinct from blue potable |
From color to construction management record
Because the stripe is fixed at extrusion, the color can be linked to the pipe’s production batch record. A utility that receives coded pipe can scan or log the batch and know the material grade, SDR, and manufacture date without opening a joint. This closes a loop between factory quality data and field asset management, which is exactly the construction-management advantage the title promises. Faygo’s line control logs stripe ratio and output per order, supporting traceability that municipal procurement teams increasingly require.
응용 산업: Municipal Water and Beyond
The dominant application for the two color marked HDPE water 파이프 압출 라인 is municipal water infrastructure, but the same marking logic serves adjacent industries that also need coded buried networks. Faygo positions these lines for water supply, drainage, gas, communication, and agricultural irrigation within its pipe extrusion program, and the marking feature extends naturally into each.
Municipal water supply and reclaimed networks
City water bureaus use coded HDPE for potable distribution, reclaimed-water irrigation, and fire loops laid in shared corridors. The colored stripe removes ambiguity when a maintenance crew opens a vault and sees four buried pipes. In construction management terms, this reduces the time spent confirming service identity before cutting or tapping, lowering both labor cost and the risk of a cross-connection that could contaminate a potable main.
Adjacent industries served by coded pipe
Beyond municipal water, the line supports agricultural irrigation districts that separate potable, fertigation, and drainage lines; industrial parks that run process water and fire water in one trench; communication and power utilities that need PE cable protection ducts visually separated from water; and rural drinking-water projects where untrained crews benefit most from color cues. Across these fields, the two color marking is a low-cost upgrade that delivers high field value, because the marking is permanent and needs no labeled tape that degrades underground.
How to Select the Right Line: Requirement-to-Model Table
Selecting the correct line starts from the diameter range and annual volume a plant must serve, then confirms the stripe coding needs. The table below maps common buyer requirements to the matching Faygo model, so a procurement team can shortlist without over- or under-specifying the extruder.
Requirement-to-model selection guide
| Buyer Requirement | Diameter Focus | 볼륨 레벨 | Recommended Model | Why |
|---|---|---|---|---|
| Residential branch supplier | DN 20 to 63 | 중간 | HDPE-TC63 | Compact, fast changeover, low footprint |
| District distribution plant | DN 75 to 160 | 중간에서 높은 수준까지 | HDPE-TC160 | Covers most city mains |
| Regional water group | DN 200 to 315 | 높은 수준 | HDPE-TC315 | Trunk and reclaimed networks |
| Transmission main contractor | DN 355 to 500 | 매우 높은 등급 | HDPE-TC500 | 가장 큰 단일 라인 용량 |
| Multi-diameter service bureau | DN 20 to 315 | 높은 수준 | TC63 + TC160 + TC315 | Full coverage, balanced utilization |
Factors beyond diameter
세 가지 추가 요소가 최종 선택을 결정합니다. 첫째, 압력 클래스 혼합: PN 16 배포용 플랜트는 PN 8 트렁크용 플랜트보다 짧은 냉각을 사용할 수 있습니다. 라인 길이를 변경합니다. 둘째, 스트립 수: 네 스트립 헤드는 단일 스트립보다 비용이 많이 들지만 다중 서비스 코딩을 위해 라인을 미래화합니다. 셋째, 유틸리티의 문서 요구 사항: 배치 추적이 필요한 경우 생산 로깅이 활성화된 라인을 지정하십시오. 비용 축에서, 다중 라인 플랜트는 프리미엄 수준의 마킹 투자를 총 출력 증가에 분산시켜 단위 길이당 추가 비용을 저가로 낮춥니다.
건설 Management Benefits of Two Color Marked Pipes
건설 management covers the lifecycle from factory dispatch to trench backfill and long-term asset records. Two color marked HDPE pipe improves every stage. At dispatch, coded pipe is sorted by color, reducing loading errors. At the staging yard, crews identify service class by sight, speeding layout. At tie-in, the correct main is selected without measurement, cutting the chance of connecting potable to reclaimed lines. At audit, the permanent stripe survives where surface paint would not, supporting accurate as-built maps.
Safety and compliance angle
Misidentifying a buried line is a safety event, not just an inconvenience. A red fire loop mistaken for a potable branch can starve hydrants; a gas-coded duct cut during water work is a hazard. The extruded stripe removes the dependence on fragile surface marks and on drawings that may not match the field. For utilities under regulatory pressure to document cross-connection controls, coded pipe is a defensible, audit-ready measure with a Low recurring cost and a High compliance return.
Efficiency and cost control
현장 시간은 파이프라인 건설의 주요 비용입니다. 트렌치에서 식별을 단축하는 것은 조인당 노동 시간을 줄입니다. 수천 개의 연결에 걸쳐 몇 분을 절약하면 절감 효과가 큽니다. 정규화된 비용 지수 100에서 마킹 기능은 프리미엄 수준의 일회성 장비 프리미엄을 추가하지만 운영 비용을 저가로 전환하고 수명 주기 비용을 중고급 수준으로 낮춥니다. 구매 팀이 쉽게 정당화할 수 있는 프로필입니다.

Maintenance, Troubleshooting, and Line Commissioning
두 색상 마킹이 표시된 HDPE 수처리 파이프 압출 라인은 정밀한 연속 시스템이며, 그 장기적인 성능은 시운전 및 정기적인 유지보수에 따라 달라집니다. Faygo는 시운전을 턴키 약속의 일부로 처리합니다: 엔지니어는 라인을 설치하고 고객의 실제 레시피에 맞게 72시간 연속 가동 테스트를 수행하며, 인수 전에 현지 운영자를 교육합니다. 전체적으로 유지보수 부담은 중간 수준으로, 라인에는 스크류, 배럴 및 절단날 외에 거의 마모 부품이 없기 때문에, 그러나 마킹 하위 시스템은 스트라이프 품질이 일관되도록 유지되도록 특별한 주의를 기울여야 합니다.
Common stripe quality issues and remedies
The most frequent marking defect is stripe width drift, which appears when the stripe extruder is not fully slaved to haul-off speed after a wall-thickness change. The remedy is to confirm the synchronized drive ratio and re-zero the stripe screw speed at the new setpoint. A second issue is stripe position error, where the mark rotates off its 90-degree spacing; this points to a loose die indexing ring and is corrected by re-torquing the head and verifying alignment with a reference gauge. Third, a wavy or uneven stripe edge usually signals pulsation in the stripe melt, resolved by checking the stripe extruder’s screen pack and, on larger lines, confirming the melt pump is engaged. None of these faults affect the pipe’s pressure rating, but they do affect identification clarity, so they are addressed during the daily visual check.
Wear parts and planned replacement
The single-screw extruder’s barrier flight and the bimetallic barrel are designed for long polyethylene service, but filled masterbatch in the stripe accelerates wear on the small stripe screw more than on the main screw. A planned replacement schedule keeps the stripe geometry stable; the free-parts allowance from the Wanplas group policy helps cover routine consumables in the first year. Cutter blades, haul-off caterpillar blocks, and screen packs are the other recurring items, all sourced against internationally recognized electrical and mechanical standards so a plant in any region can restock locally. On a normalized cost index of 100, planned maintenance sits at a Low to Medium band and prevents the Very High cost of an unplanned stop during a contracted municipal delivery window.
Energy and utility planning
에너지 비용은 수지 비용 다음으로 가장 큰 반복 운영 비용입니다. 압축기 드라이브가 소비량을 주도하며, 그 다음으로 진공 펌프와 냉각수 순환이 있습니다. Faygo 라인은 인버터로 구동되는 드라이브와 절연된 배럴 구역을 사용하여 대기 비용을 저가로 유지하며 지능형 제어는 실제 용융 필요에 따라 영역을 고정 전체 출력으로 구동하는 대신 열용량을 조절합니다. 공장에서는 냉각수에서 열을 회수하여 냉난방 공사에서 사용함으로써 비용을 낮출 수 있습니다. 장기적인 설계 수명을 가진 인프라에 파이프를 공급하는 계약에 따라 수주하는 도시 공급업체에게는 이러한 에너지 절감 전략이 수익성을 보호합니다.
자주 묻는 질문
시간이 지남에 따라 색상 스트립이 탈색될까요?
아닙니다. 스트립은 파이프 본체와 동일한 폴리에틸렌 화학물질에서 동일하게 압출되어 캘리브레이션 시 인터페이스에서 용접되므로 접착 경계가 실패하지 않습니다. 두 레이어가 동일한 재료 계열을 공유하기 때문에 마크는 매몰, 야외 부분에서의 UV 노출 및 반복적인 취급에도 견딜 수 있습니다. 이러한 이유로 인프라의 수명 주기가 수 십 년인 경우 압출 스트립 마킹이 테이프 또는 인쇄된 마크보다 선호됩니다.
한 라인은 서로 다른 주문에 대해 다른 색상의 스트립을 생산할 수 있습니까?
예. 스트립 색상은 작은 동일 압출기에서 공급되는 마스터 배치를 통해 제공되므로 색상을 변경하는 것은 마스터 배치 호퍼를 변경하고 스트립 배럴을 청소하는 것뿐입니다. 많은 공장에서는 하루 종일 검은색 기반 파이프를 운영하고 파이프트랩 주문에서 파이프트랩 재활용 주문으로 스트립 색상을 전환하여 변경 시간이 짧고 활용률이 높습니다.
Does the line handle PE100 and PE80 grades?
예. 단일 스크류 장벽 압출기는 일반적으로 폴리에틸렌을 대상으로 조정되므로 PE80 및 PE100 천연 펠릿을 사용하면 하드웨어를 변경하지 않아도 됩니다. PE100은 동일한 압력 등급에서 파이프 벽을 더 얇게 만듭니다. 이는 주어진 출력을 기준으로 미터당 시간량을 높입니다. 캘리브레이션 슬리브와 하우오프는 PE100 벽이 요구하는 더 엄격한 허용 오차를 유지하므로 라인은 가장 자재 효율적인 도시 급수 등급을 지원합니다.
한 라인은 서로 다른 압력 등급의 파이프를 생산할 수 있습니까?
예. 압력 등급은 SDR을 통해 설정되며 다이 간격, 하우오프 속도 및 압출기 출력을 통해 제어됩니다. 공장에서는 PN 16 배포 파이프와 PN 8 트렁크 파이프를 동일한 라인에서 생산하기 위해 벽 두께를 ISO 4427 및 지역 동등품과 같은 표준의 범위 내로 조정할 수 있습니다. 72시간의 선적 전 테스트는 생산 속도에서 외경 및 벽의 허용 오차를 확인하므로 파이프는 현장 재작업 없이 부트 용접 및 전기 용접 조인에 적합한 상태로 선적됩니다.
Faygo 압축 파이프 라인에서는 파이프 치수가 얼마나 정확합니까?
Faygo 압축 파이프 라인은 진공 캘리브레이션 슬리브, 서보 제어 다중 캐터필러 하우오프 및 선택적 용융 펌프를 사용하여 외부 직경 및 벽 허용 오차를 ISO 4427 및 지역 동등품과 같은 표준의 범위 내로 유지합니다. 72시간의 선적 전 테스트는 생산 속도에서 치수 안정성을 확인하므로 파이프는 현장 재작업 없이 부트 용접 및 전기 용접 조인에 적합한 상태로 선적됩니다.
두 가지 색상 마킹을 추가하는 비용 프로필은 어떻게 됩니까?
On a normalized cost index of 100, the two color marking configuration carries a Premium-level one-time equipment premium of roughly 8 to 12 percent over an equal single-color line, driven by the stripe extruder and indexed die head. The recurring material cost is Low because the stripe is a thin surface layer. The lifecycle return is 높음에서 매우 높음까지 through fewer misidentifications, faster trench work, and easier inventory control, which is why municipal suppliers view the marking option as a sound investment rather than a luxury.
생산 데이터가 유틸리티 추적에 사용할 수 있습니까?
Yes. The line control logs order parameters including stripe ratio, output, and run time, which can be tied to batch and reel identity. A utility receiving coded pipe can therefore link a specific stripe color and batch to material grade, SDR, and manufacture date, supporting asset management and cross-connection control documentation without opening the pipe. This batch-level record is part of Faygo’s intelligent control capability.
결론
A two color marked HDPE water 파이프 압출 라인 turns a standard polyethylene pipe into a self-identifying asset that pays back across the whole construction-management cycle, from factory sortation to trench tie-in to decades-long asset records. Faygo, Wanplas 공장, delivers this capability across diameters from DN 20 to DN 575 with the HDPE-TC63, HDPE-TC160, HDPE-TC315, and HDPE-TC500 models, each built on a barrier single-screw extruder, synchronized co-extrusion stripe control, vacuum calibration, and servo haul-off. The line supports PE80 and PE100 grades, multiple pressure classes through SDR control, and a color-code mapping that utilities can adopt for potable, reclaimed, fire, and other services.
For municipal water suppliers and pipe plants, the engineering case is clear: the marking function adds a Premium one-time premium on a cost index of 100 while delivering Low recurring cost and High lifecycle value. Backed by Faygo’s 22 years of pipe-extrusion experience, CE and ISO certification, 72-hour pre-delivery testing, and the Wanplas group promise of USD 500 free parts every year plus 24/7 support, the two color marked HDPE line is a practical, future-proof investment. If you are planning a new coded-pipe workshop or upgrading an existing line, send your target diameters, pressure classes, stripe coding scheme, and annual volume to Faygo for a tailored configuration, a factory audit invitation, and a sample trial run arranged through the Wanplas team.
