Product characteristic1It has higher strength, stiffness, impact resistance than plastic pipe.
2Corrosion resistance on both surfaces, it has same corrosion resistance with plastic pipe.
3High work temperature, low thermal conductivity, heat insulation for outer wall is not required when it is used in winter, and no moisture condensation when it is used in summer.
4Smooth and neat inner wall, no scaling, head loss is 30% lower than steel pipe.
5Pipe connection adopts electric melting connection which is the mature technology, The electric melting joint has strong axial tension resistance. The pipe fittings have many specifications.
6Light weight, easy transportation and construction. Overall reliability for pipes is high.
7Low cost, health and non-toxic, it is the best substitute for galvanized pipe.
