plastic machinery This production line is mainly for producing PE-C fiber helix corrugation pipes. This kind of pipe is made from special structure and mixture with HDPE and carbon fiber. It has characteristics of high intension, high toughness, anti-corrosion, light weight, long life and no deformation. It is widely used to irrigate andprotect the surface of cable and wire, and drain and feed gas. It is an ideal substitute of iron pipes and PVC pipes.This efficient extrusion line is researched by our company. It has novelty structure, good appearance and high efficiency with high performance extruder and automatic system adopted.Prestressed vacuum helix production line is the second products with new researches on the basis of corrugated pipe production line. It has characteristics of simple manufactory, low prices, and convenient construction, doesn't need to connect.It also has fine perdurable performance and fatigue resistance, which are superior to prestressed-corrugated production line.
