For years, the large diameter (defined as 16 in. and above) water pipe market has been represented by steel pipe (SP), precast concrete cylinder pipe (PCCP), ductile iron pipe (DIP), and PVC (polyvinyl chloride) pipe. HDPE pipe, on the other hand, comprises just 2 to 5% of the large diameter water pipe market.
HDPE double-wall corrugated pipe is extruded from high-density polyethylene with corrugated outer wall and smooth inner wall at the same time fused and extruded at one time, it has the characteristics of good corrosion resistance, high insulation, strong low temperature resistance, good sealing performance, no leakage, etc.
HDPE pipes are pipes made of high density polyethylene (HDPE). They are sometimes referred to as thermoplastic pipes. HDPE pipes are flexible plastic pipes used in various applications such as rural irrigation, gas mains, water pipes, slurry lines, drainage system pipes, electrical and communication system pipes, etc.
