1,light in weight,convinient for transportation,installation and construction

2,Good flexibility makes the laying convienient and economic,pipes can be coiled
and bended during the construction.

3,Embrittlement cracking temperature is low and pipe materials have excellent
low temperature resistance performance,so construction can be made under low
temperature in winter and no preheating is needed for bending pipes.This soves
the problem of economic loss caused by low temperature resulting in the
incapability of construction .

4,Excellent anti-impact performance,good heat dispersion
