Large diameter steel reinforced PE composite corrugated pipe is by the company a number of patented technology forming a high density polyethylene (PE) as matrix (inner and outer) and winding wall composite corrugated steel pipe, pipe wall structure consists of three layers: the inner layer is a special structure of polyethylene (PE) strip the winding made of inner pipe, outer pipe in the inner inlaid strip by corrugated one reinforced strip, covered with corrugated reinforced polyethylene (PE), thus forming the overall steel reinforced PE corrugated pipe production line, can produce steel reinforced PE corrugated pipe from the pipe diameter DN200-DN3000, solves the problems of thermal expansion coefficient between the plastic and steel pipe cracking due to different problems, with light weight, reliable composite pipe, steel ring is high (above SN10) and other advantages, is currently used in municipal, agricultural irrigation and other fields the best large diameter drainage, sewage pipe. |
