|---|---|
This system features three independent extruders—each optimized for its specific layer—to create pipes with excellent pressure resistance (up to 200 bar) and chemical durability. The inner core layer (HDPE/PP) ensures smooth flow and corrosion resistance; the middle reinforcement layer (glass fiber/aramid/steel wire) provides structural strength; and the outer layer (UV-stabilized HDPE) offers environmental protection. This layered structure enhances pipe lifespan by 50% compared to single-layer alternatives.

Oil & Gas Industry:
Used for subsea pipelines (up to 500m water depth) and onshore gathering lines, offering corrosion resistance to hydrocarbons and saltwater (compliant with API 15S and DNV GL-ST-F101).
Mining Industry:
Supports slurry transportation pipes (for coal, mineral ores), with abrasion resistance (weight loss ≤50mg per ASTM G65) and high impact strength (Charpy impact ≥20kJ/m² at -40°C).
Water Treatment:
Ideal for high-pressure water mains (municipal water supply) and sewage force mains, resisting chlorine and chemical degradation (compliant with ISO 4427 and AWWA C906).
Renewable Energy:
Used in hydrogen transport pipelines (up to 35MPa) and geothermal fluid transmission, with material compatibility tested per ISO 17268 (hydrogen service) and API 17E (geothermal applications).
Q: What reinforcement materials are compatible?
A: The line supports continuous glass fiber rovings (tensile strength ≥2,500MPa), aramid fibers (modulus ≥70GPa), and galvanized steel wires (yield strength ≥400MPa), with customizable impregnation systems for each material.
Q: How is the pipe’s pressure resistance tested?
A: Every production batch undergoes hydrostatic testing at 1.5x the rated pressure (e.g., 300 bar for 200 bar rated pipes) for 1 hour, with pressure decay monitored to ≤5% of initial pressure, ensuring no leaks or structural deformation.
Q: What is the minimum bend radius of the pipes?
A: The pipes maintain structural integrity with a minimum bend radius of 5x their outer diameter (e.g., 1.5m for 300mm OD pipes), enabling flexible installation in tight spaces without joint failure.
Q: Does the line support anti-static coatings?
A: Yes, the outer layer can be formulated with carbon black or conductive additives to achieve surface resistance ≤10?Ω, meeting ATEX requirements for explosive environments in mining and oil & gas applications.
