UV Resistant Multi Layer Buried PE 파이프 압출 Equipment For Outdoor Long Distance Water Transmission Works

Faygo, Wanplas 공장 with 22 years of dedicated experience in plastic pipe and profile extrusion, operates three specialized factories covering 26,650 square meters in Zhangjiagang and supplies water, gas, drainage and irrigation projects through the Wanplas group network of more than 100 exported regions. This article explains how UV resistant multi layer buried PE pipe extrusion equipment is built and specified for outdoor long distance water transmission works. When a pipeline crosses open terrain, follows a mountain ridge, runs along a coastal plain, or connects a remote mining or industrial park to a source, the pipe is exposed to three threats that a conventional single layer tube handles poorly: ultraviolet radiation during storage and installation, point loads and abrasion after burial, and internal friction that raises pumping cost over decades of service. A multi layer co-extrusion line answers each threat by placing the right material in the right position of the wall, and this guide covers the layer designs, the UV stabilization chemistry, the extrusion line configuration, the defect diagnosis, the material compatibility, the buried performance, the standards, the capacity model, the configuration mistakes to avoid, and the selection logic that turns an engineering requirement into a concrete Faygo machine list.

Why Long Distance Buried Water Transmission Needs Multi Layer Pipe Structure

Long distance water transmission is defined here as trunk and branch mains that carry water across regions, between a treatment plant and a city, from a reservoir to an irrigation district, or from a source to a mining or industrial park. These pipelines are laid in open trenches, buried at a designed depth, and expected to perform for decades with minimal intervention. The operating pressure is moderate to high, the diameter is often large, the route is long, and the pipe spends weeks or months above ground before it is finally covered. A single layer PE100 pipe is an excellent pressure pipe, but in this duty cycle it exposes its whole wall to conditions that a layered design manages far better.

The Three Weak Points Of Single Layer Pipe

The first weak point is ultraviolet exposure during the construction window. PE is a polyolefin and its carbon-hydrogen backbone is slowly broken by solar ultraviolet, especially the UV-B fraction. A single layer black pipe resists this because carbon black is an outstanding UV absorber, but a single layer colored or natural pipe can lose elongation and surface integrity if it sits in the sun for too long before burial. The second weak point is the buried environment. Once in the trench, the pipe rests on stones and receives point loads from sharp aggregate, and a single homogeneous wall has no sacrificial surface to absorb scratching and abrasion. The third weak point is the inner surface. Over a long distance a smooth bore saves pumping energy, yet a standard pipe wall is not optimized for the lowest friction, and in abrasive duty such as sediment-laden mine water the inner surface wears.

How Multi Layer Co Extrusion Solves Each Weakness

Multi layer co-extrusion solves the first weakness by giving the pipe a dedicated outer skin formulated for ultraviolet stability, either a carbon black rich black layer or a hindered amine light stabilizer (HALS) based colored layer, so the structural core never sees the full radiation dose. It solves the second weakness by placing a tougher or more abrasion resistant outer layer on the outside, and in trenchless or pipe-jacking duty a separate polypropylene based outer protection layer can take the scraping without damaging the pressure-carrying core. It solves the third weakness by adding a dedicated inner layer with a lower friction surface or a more wear resistant formulation, improving the Hazen-Williams C value and extending service life in abrasive flow. The economic logic is simple: spend a thin, optimized skin on the outside and inside, and reserve the expensive PE100 structural material for the core where pressure is carried.

Typical Multi Layer Structure Schemes

다음 레이어 구성은 야외 장거리 수송 작업에 사용되는 실제 구성입니다. 각 구성은 기능과 비용의 균형을 이루며, 적절한 선택은 파이프가 검은색인지 색상인지, 스트라이프로 식별해야 하는지, 개방형 트렌치 또는 트렌치리스 방식으로 설치되는지, 그리고 현지 자외선 및 마모 정도에 따라 달라집니다.

Layer Scheme	Outer Layer (0.3 to 1.5 mm)	Core	Inner Layer (0.3 to 1.0 mm)	Function And Application	Cost Level
Two layer	PE100 body plus UV 안정성 있는 외부 피부 (black high carbon black or colored HALS system)	PE100 structural	Same as core (no separate inner)	General buried trunk and branch mains; simplest co-extrusion upgrade from single layer	저전압
Three layer (smooth bore)	UV 안정성 있는 외부 피부	PE100 structural	Smooth or low friction inner layer	Long distance pumping mains where friction loss is significant; improves Hazen-Williams C	중간
Three layer with stripe	UV 안정성 있는 외부 피부	PE100 structural	Core plus co-extruded stripe (blue for drinking water, yellow for gas)	Identified buried service pipe; color coding without full-body pigmentation	중간
PP outer protection	폴리프로필렌 기반의 긁힘 방지 외부 레이어 (타이 또는 기계적 인터록 포함)	PE100 structural	Optional low friction inner	Trenchless, no- excavation, and pipe-jacking installation where outer scraping is severe	높은 수준
Premium multi layer	UV stable outer plus optional stripe	PE100 structural with recycled-content outer permitted	Low friction and abrasion resistant inner	Harsh outdoor, high altitude, coastal, abrasive mine water duty with full optimization	매우 높음에서 프리미엄까지

The outer layer thickness typically runs from 0.3 mm on small diameters to 1.5 mm on large diameters, while the inner functional layer runs 0.3 to 1.0 mm. These thin skins are the reason the co-extrusion line must control layer thickness to a tight tolerance; a skin that drifts too thin loses its protection, and one that drifts too thick wastes stabilized compound. The line speed and screw sizing are selected so the thin layers stay uniform over the whole production run.

UV Resistance Technology Deep Dive

Ultraviolet resistance is the technical high point of this equipment, because the pipe must survive a long above-ground exposure window and then a multi-decade buried life where the top of the pipe can still receive some indirectly reflected radiation in shallow trenches. The stabilization system is built into the outer layer compound and is applied by the co-extruder, so the extrusion line and the stabilization chemistry are inseparable design topics.

Carbon Black System

For black pipe, carbon black is the primary UV stabilizer. Standards GB/T 13663 and ISO 4427 require a carbon black content in the range of 2.0 percent to 2.5 percent by mass. The primary particle size should be near 15 to 25 nm, because fine particles give the highest shielding per unit mass and the best dispersion. The dispersion rating must be no worse than level 3, measured on a microtome slice; a poor dispersion with agglomerates creates weak points where cracks initiate. Carbon black that is under-dosed, over-dosed, or poorly dispersed sharply reduces the weatherable life of the pipe, and because the outer layer is thin, the dispersion quality of the co-extruded skin matters even more than in a fully black single layer pipe.

HALS And UV Absorber For Non Black Pipe

For blue, white, or other colored pipe, carbon black cannot be used because it would turn the pipe black, so the stabilization relies on a hindered amine light stabilizer (HALS) system combined with a UV absorber. HALS does not absorb UV directly in the way carbon black does; instead it traps the free radicals generated by photo-oxidation and regenerates, giving a persistent protective cycle. A UV absorber in the same compound absorbs high-energy photons before they reach the polymer backbone. Titanium dioxide is often added for opacity and whiteness, but it has a double-edged effect: it blocks radiation and improves appearance, yet in some systems it can participate in photocatalytic reactions or demand careful dispersion, so its grade and loading must be chosen with the full stabilizer package in mind. The co-extruder must meter these additive-rich compounds accurately because the outer skin is thin and the stabilizer concentration is high.

Antioxidant System And OIT

Ultraviolet protection alone is not enough, because heat during extrusion also ages the polymer. A hindered phenolic antioxidant is paired with a phosphite co-stabilizer to protect the melt during processing and to sustain the buried service life. The oxidation induction time, or OIT, measured at 200 degrees Celsius, is the standard control value, and a properly stabilized compound should show an OIT of 20 minutes or more. The risk is OIT loss: every extrusion pass consumes some antioxidant, and a pipe made from multiple extrusion cycles or from regrind can arrive at the customer with a reduced OIT. The co-extrusion line should therefore process the stabilized outer compound at the lowest practical melt temperature and avoid prolonged residence time, protecting the OIT that the laboratory value promises.

Accelerated Aging Tests

Weathering is verified by accelerated aging. The ISO 4892-2 xenon-arc method simulates solar radiation with controlled spectrum, temperature, and humidity, while QUV fluorescent UV cycling stresses the surface with alternating UV and condensation. A common target total radiant exposure is around 3.5 GJ per square meter, a value used as a correlation point to an assumed number of outdoor years depending on the site’s annual ultraviolet dose. The acceptance criterion is not merely survival but retention of properties: the elongation at break after aging should remain at or above 50 percent of the unaged value, and the pipe must not show brittle transition or surface cracking. Because the correlation between laboratory radiant exposure and real outdoor years depends on latitude, altitude, and climate, the test result is reported as retained properties at a defined dose rather than as a single guaranteed year.

테스트	Condition	Target Value	Acceptance Criterion
탄소 블랙 함량	Thermogravimetric or chemical method	2.0에서 2.5%	Within GB/T 13663 and ISO 4427 range
탄소 흑연 분산제	Microtome slice rating	Rating 3 or better	No agglomerates above limit
산화 유도 시간	200 degrees Celsius, OIT	20 minutes or more	No premature oxidation
제논 아크 노화	ISO 4892-2	About 3.5 GJ per square meter	No brittle transition, no cracking
Elongation retention	After aging	50 percent or more of original	Property retained, not merely intact

Outdoor Storage And 건설 Exposure Management

A stabilized outer layer extends the allowable exposure window, but it does not make the pipe immune. Best practice on site is to cover stored pipe, limit direct sun exposure, and bury within the project’s planned window. The exact allowable exposure time depends on local ultraviolet intensity, which is measurably higher at high altitude and near the coast because of thinner atmosphere and reflected radiation from water and sand. The extrusion line’s job is to deliver a pipe whose stabilized skin matches the site severity, and the supplier’s installation note should state the exposure limit for the specific compound and color. Managing the exposure window is the cheapest insurance against a pipe that enters the trench already aged.

다중 층 압출 장비 구성

A multi layer buried PE pipe line is a sequence of precisely controlled stations. Each station has a parameter window that the Faygo control system manages, and the line is only as good as its weakest station. The configuration below is the full station list for a line capable of two to four layer PE pipe with a UV 안정성 있는 외부 피부.

Main Extruder

The main extruder plasticizes the PE100 core. The screw diameter ranges from 75 mm on smaller lines to 150 mm on large diameter lines, with an L/D ratio of 33:1부터 38:1까지. A barrier screw design improves homogenization and lowers melt temperature, which protects the OIT. The specific energy consumption of a well-tuned main extruder is in the range of 0.20 to 0.28 kWh per kilogram of output, and reducing this number through screw design and temperature control is a direct contribution to the line’s energy efficiency.

Co Extruder (One To Three Units)

The co-extruders deposit the thin outer skin, the inner skin, and the stripe. Each is a small single-screw extruder with a screw diameter from 30 mm to 65 mm, fitted with independent temperature control and a gear pump for stable pressure. Small flow with high accuracy is the defining requirement: the outer skin may be only a few percent of total mass, yet its thickness must stay within about plus-or-minus 10 percent along the entire length. The gear pump removes the pulsation of the small screw so the layer does not thicken and thin as the screw rotates.

다중 레이어 코 익스트루젼 다이 헤드

다이 헤드는 라인의 핵심입니다. 쌓인 나선형 맨드렐 디자인은 각 용융 흐름을 적절하게 병합하여 층을 동심원 형태로 쌓습니다. 각 층의 경계면 온도는 각 층이 과열되지 않도록 제어해야 하며, 경계면 접합 강도는 각 층의 탈각 테스트로 확인됩니다. 다이 헤드 압력은 일반적으로 15 MPa에서 30 MPa 사이입니다. 잘 설계된 다이 헤드는 최소한의 퍼지로 빠른 색상 및 층 변경이 가능하여 제품 교체 시 얇은 층의 정확성을 보호합니다.

진공 캘리브레이션 탱크

The vacuum calibration tank fixes the outside diameter using a sizing sleeve under vacuum. The vacuum level is set from minus 0.02 MPa to minus 0.06 MPa depending on diameter and wall thickness, and the sizing sleeve finish controls the outer surface gloss and the fidelity of the stripe. Because the outer skin is the UV stable layer, its surface quality is not cosmetic only; a clean, well-calibrated surface distributes the stabilizer and presents a uniform weathering face.

냉각수 탱크

The cooling water tank solidifies the wall. It is multi-stage with a water temperature gradient from 15 degrees Celsius to 25 degrees Celsius to avoid thermal shock, and its total length is matched to wall thickness: thick-wall large diameter pipe needs cooling lengths in the 12 m to 24 m range. Insufficient cooling leaves residual stress in the wall, which later shows as distortion or reduced resistance to slow crack growth.

내부 냉각 및 잔류 응력 제어

대구경 파이프의 경우 내부 냉각은 응고 속도를 가속화하고 라인의 속도를 높여주지만, 잔류 응력과 균형을 맞춰야 합니다. 제어된 내부 냉각은 응고 시간을 단축하고 타원성 제어를 개선하지만, 통제되지 않은 내부 냉각은 벽에 응력 패턴을 동결시킬 수 있습니다. 라인은 내부 냉각과 충분한 외부 배열을 통해 파이프가 최종적으로 낮은 잔류 응력으로 배열됩니다.

캐터필러 하울 오프(Haul Off)

하우오프는 파이프를 통제된 폐쇄 루프 라인 속도로 당겨냅니다. 당겨지는 속도는 직경과 필요한 견인력에 따라 4, 6, 또는 8 개의 캐터필러 트랙을 사용하며, 견인력은 약 15 kN에서 대형 파이프의 경우 120 kN까지 다양합니다. 라인 속도는 마스터 변수로, 스크류 속도와 함께 벽 두께를 설정하며, 안정적인 하우오프는 전체 벽과 각 레이어를 허용 범위 내에 유지합니다.

On Line Measurement

On-line measurement is what makes multi layer production controllable. An ultrasonic multi-layer thickness gauge displays each layer separately, not just the total wall, and the line also measures outside diameter, ovality, and meter weight. The meter weight signal closes the loop on haul-off speed, and the layer thickness signal triggers an alarm when a skin drifts outside its band. Without layer-resolved measurement, a producer only knows the total wall is correct and cannot prove the UV skin is present and uniform.

Marking, Chipless Cutting, Tipping And Coiling

하우오프의 하류에서 라인은 파이프를 표시하고, 파이프를 절단하며, 파이프가 보어에 오염될 수 있는 칩이 발생하지 않도록 합니다. 파이프를 절단하고 처리할 때는 외부 UV 피부가 손상되지 않도록 해야 합니다. 파이프의 절단 부분에 스크래치가 생기는 것은 노화의 시작점이 됩니다. 코일 처리 옵션은 작은 직경 파이프를 코일로 운송하여 현장에서 접합 수를 줄이는 데 적합합니다.

Multi layer pipe fails in specific, recognizable ways. The table below maps each defect to its root cause and the corrective action, and it is the operating reference for the line technician. Most co-extrusion defects trace back to layer temperature imbalance, co-extruder flow instability, die head flow imbalance, material incompatibility, or gear pump pulsation.

Inner drag marks	Sizing sleeve or core tooling scratches, insufficient internal lubrication	Polish or replace sizing sleeve, review inner layer formulation

Materials, Compatibility And Buried Performance

The material logic of a multi layer PE pipe starts with the core. PE100 is the structural grade for buried water transmission because of its high stress crack resistance and long-term hydrostatic strength. The outer layer is best made from the same PE family, which gives the best compatibility and a naturally bonded interface without a tie layer. A polypropylene outer protection layer is possible for trenchless duty but requires either an adhesive tie layer or a mechanical interlock design, because PE and PP are not directly compatible at the interface. Regrind may be used in the outer protection layer up to a defined上限 that protects the weatherable life, but over-using regrind in the UV skin is a common cause of premature failure. The melt flow rate, or MFR, of each layer should be matched within about two times of one another so the layers flow and bond consistently through the die head.

Buried Engineering Performance

In the ground, a buried PE pipe is a flexible pipe whose ring stiffness and soil support work together; the pipe deflects slightly and the surrounding soil carries most of the load. Point loads from stones are managed by a properly graded bedding and by the tougher outer layer, which absorbs the local abrasion. The slow crack growth resistance is verified by the notched pipe test, and the rapid crack propagation resistance by the S4 test, both relevant to long pipelines that must not fail by a single running crack. For abrasive duty such as sediment-laden mine water, the inner layer wear resistance protects the bore. The inner smooth layer improves the Hazen-Williams C value, lowering friction loss over the long run and reducing pumping energy. Joints are made by butt fusion or electrofusion fittings, and for multi layer pipe the welding note must state whether the outer skin should be removed in the joint area; when the outer layer is the same PE family this is usually unnecessary, but for striped or specially formulated outer layers the fabricator follows the supplier’s instruction. The equipment supplier provides this welding guidance during commissioning.

Standards Compliance Checklist

The following standards frame the specification and verification of UV resistant multi layer buried PE pipe and the line that produces it. ISO 4427 covers PE piping systems for water supply. GB/T 13663 is the Chinese national standard for PE water pipes and sets the carbon black and dispersion requirements. EN 12201 is the European standard for 수도 공급용 PE 파이프. ISO 4892-2 defines the xenon-arc weathering method. ISO 9080 is the method for extrapolating long-term hydrostatic strength. ASTM D3350 classifies PE pipe materials. GB/T 18742 is the reference for PP-R pipe and a useful对照 for the PP outer layer route. For drinking water contact, GB 4806, NSF/ANSI 61, and WRAS define the compliance requirements. CE marking applies where the European machinery and product directives are relevant, and ISO and CE references appear in the documentation as plain text only.

Long Distance Transmission Engineering Considerations

Beyond the pipe itself, the line design must serve the project. Long distance routes decide pipe segment length and transport: fixed lengths of 6 m or 12 m are standard for large diameters, while small diameters may be coiled to cut joint count. Field welding efficiency drives the joint spacing and the welding crew size. Along the route, elevation difference sets pressure zoning, and water hammer protection through air valves and slow-closing controls protects the line. Climbing and crossing obstacles call for higher pressure classes at the low points. High altitude increases ultraviolet intensity and therefore the stabilizer demand of the outer skin. Coastal sites add salt spray, which the outer layer formulation and the storage discipline must address. Desert routes impose large day-night temperature swing that the material’s thermal expansion and the bedding design must absorb. The extrusion line is specified so the pipe it makes matches the most severe condition on the route, not merely the average.

용량 및 에너지 효율성

Capacity is expressed in kg/h and m/min, and the co-extrusion ratio changes the total line output because the co-extruders add a small but real mass and thermal load. The specific energy consumption of the main extruder is 0.20 to 0.28 kWh/kg, and the overall line efficiency is tracked as OEE, or overall equipment effectiveness, in percent. Changeover between diameters and between layer structures is a planned downtime, and the target is to minimize it through quick die head purge and recipe recall. The good product rate is tracked in percent, and the unit conversion cost is expressed as an index with the baseline set at 100 points so that configuration choices can be compared without disclosing absolute cost. The most efficient line is not the one with the highest screw speed but the one that holds layer tolerance and good product rate at the project’s required output.

일반적인 구성 오류

다중 레이어 PE 파이프 라인에서 자주 발생하는 오류는 예측 가능합니다. 너무 작은 크기의 코-익스트루저는 얇은 외부 피부를 안정적으로 유지할 수 없으므로 레이어가 이동합니다. 코-익스트루저에 기어 펌프가 없는 라인은 피부의 움직임을 스크류의 진동에 맡깁니다. 제어되지 않은 레이어 인터페이스 온도는 약한 결합을 유발합니다. 총 벽 두께를 측정할 때 레이어별로 구분하지 않으면 누락되거나 얇은 UV 피부가 있습니다. 외부 레이어에서 너무 높은 재생 비율을 사용하면 내후성 수명이 손상됩니다. 충분한 냉각 길이로 인해 잔류 응력이 벽에 축적되어 나중에 왜곡이나 균열 저항력이 감소하는 것으로 나타납니다. 이러한 모든 사항은 위에서 설명한 스테이션 목록과 제어 로직을 통해 방지되며, 이러한 사항은 사전 납품 72시간 시험이 드러내도록 설계되었습니다.

변경 절차 SOP 및 시간 목표

체계적인 변경으로 라인을 수익성 있게 운영할 수 있습니다. 표준 운영 절차는 다음과 같습니다. 코-익스트루저를 정지하고 다음 화합물로 다이 헤드를 청소한 후, 제어 시스템에서 레시피를 불러오고, 새로운 직경에 맞는 크기 조절 슬리브와 교정 도구를 교체하고, 초음파 게이지를 다시 제로화한 후, 짧은 시험 길이를 실행하고, 레이어 두께와 직경을 확인한 후, 생산에 착수합니다. 직경 변경 시 시간 목표는 도구 사전 준비로 단축됩니다. 레이어 구조 변경 시 시간 목표는 다이 헤드의 빠른 청소 설계와 레시피 관리 시스템으로 단축됩니다. 각 변경 절차를 문서화하면 이후 시간 목표를 더욱 단축할 수 있습니다.
