Lifesaving Pipe Production Line for Tunnel
Review
Description
ultra high molecular weight polyethylene (UHMWPE) could work in the -269℃~80℃，strong wear resisting,more and more popular in petroleum transportation, and acid liquid, lye,etc.
UHMWPE Pipe is with better heat insulation than stainless steel pipe，alloy tube and steel-plastic pipe.
It could replace the above pipes when transport petroleum in cold area or winter.
Widely used for lifesaving in tunnel.
Below is test result for UHMWPE and other materials:
