Pipe wall structure consists of three layers: inner layer is a continuous solid wall inner layer tube, then in the continuous steel band pressed into a nearly "U" type spiral steel rib wrapped inside, outside two layers hot melted polyethylene between, putting the high strength of steel and polyethylene's flexibility, corrosion resistance, wear resistance together, can make the tube achieve ring stiffness level up to 16KN/m, making the large diameter plastic buried ground drainage tube can only reach the SN8 limit.

Kɔmpaniɛn ye kɔc cɔl cJ/T225-2006 "Polyethylene (PE) spiral corrugated tubes for buried drainage" looi. New structure and scientific reasonable forming process, make the pipe have a unique little bit, at the same time as traditional drainage pipe, has sealing reliable, long service life, flexible earthquake resistance, light weight, easy construction and fast and other advantages, easy connection, no leakage.
