Introduction
Two-color HDPE co-extruded pipe is a new type of pipe made of high-density polyethylene resin using a composite extrusion molding process. Due to its high strength, corrosion resistance, and non-toxicity, it is widely used in the field of water supply pipe manufacturing and has secured a solid position in China's pipe market.
Co-extruded pipe technology has been around for years but had typically been more expensive than standard black polyethylene (PE) pipe. Xinhengde has invested in new state-of-the-art extrusion machinery that can produce co-extruded PE pipe very efficiently.
Description of HDPE Yellow Co-extruded Pipe
PE100 pipe is manufactured with a highly reflective yellow exterior. This coating is extruded at the same time as the main pipe (via co-extrusion), forming an integral part of the pipe. This means more than 95% of the pipe is made of standard black PE material, with a thin yellow coating on the outside to reflect sunlight and reduce the amount of absorbed heat.

Ultra-violet (UV) resistance.
A lower pressure rating can be used as the lower operating temperature reduces the need for pressure de-rating, enabling thinner-walled pipes to be used. This provides cost savings both in materials and through increased flow rates.
Reduced thermal expansion/contraction means less need to “snake” pipelines.
Flexibility allows the pipeline to accommodate topographical features.
An excellent solution for above-ground applications including temporary water supply.
Co-extruded yellow HDPE pipe can be joined with electrofusion fittings, butt welding equipment or compression fittings.
High pipe stiffness with excellent resistance to collapse under vacuum effect.

| Nominal pressure (PN) is based on C = 1,25 and an operating temperature of 20°C. Weight is calculated using DN and Minimum wall plus 6% for use in estimating fluid flow. Actual ID will vary. When designing components to fit the pipe ID, refer to pipe dimensions and tolerances in the applicable pipe manufacturing specification. To obtain pressure in psi, multiply bar by 14.5 (1 bar ≈ 14.5 psi). |
