Product characteristic:1It 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
6Lightweight, easy transportation and construction, overall reliability for pipes is high
7Low cost, health and nontoxic, it is the best substitute for galvanized pipe
