Product Description

 

HDPE Pipe is used for Sand delivery pipe, mud discharge pipe, dredge pipe, oil delivery pipe, mine pipe,water pipe.HDPE is a high degree of crystallinity, non-polar thermoplastic resin, the characteristics are non-toxic, tasteless,and odorless.

HDPE Dredge Pipes Advantage

bended under water,and excellent anti-wave.

The concave-convex is within 30°of area, can be connected directly on land.

Good wear-resistance, anti-aging, strong corrosion resistance, anti-uv, long service time.

Flange connection,smooth outer and inner wall,higher transmission effifiency than steel pipe 20% to 30%.

Either on land or water for using,total engineering cost is low, high efficiency, safer and more convenient.
