performance characteristics of (UHMWPE Mining pipe、UHMWPE Dredge Pipe、UHMWPE Roller Pipe) Ease of transport and construction As a kind of flexible pipes, its length can be customised so as to reduce the number of joints. The weight of the pipe is approximately 1/2 of the steel tube, 1/3 of the cement pipe, which reduces the use frequency of large installation equipment. High composite strength The polyethylene and coated steel wires are composited by using special modified material; composite strength≥15N/mm.
