Product Description

Steel Belt Reinforced Spiral Corrugated HDPE Pipe Instruction
Steel belt reinforced spiral corrugated HDPE pipe combines the rigidity and high strength of steel with the corrosion resistance, abrasion resistance and flexibility of plastics which make the pipe reach the three levels of ring stiffness of SN8, SN10,SN12.5, and SN16. It has broad application prospects and is currently the first-choice product to replace large-diameter traditional drainage pipes.
