Product Description

Steel wire skeleton plastic (polyethylene) composite pipe is a new type of improved copper skeleton composite pipe, this pipe is also known as srtp pipe, it is the use of high-strength over-plasticized steel wire skeleton and thermoplastic polyethylene as the raw material, copper wire winding network as polyethylene as a reinforcing body of the polyethylene plastic pipe, high-density polyethylene as the matrix, the use of high-performance HDPE modified bonding resin will be steel wire skeleton and internal and external high-level density polyethylene closely together, so that it has an excellent composite effect, and has the respective advantages of steel pipe and plastic pipe.

Product performance

1. Higher compressive strength and creep resistance.

2. With more than ordinary pure plastic pipe rigidity, impact resistance, similar to the low coefficient of linear expansion of copper pipe.

3. Smooth inner wall, no scaling, small friction resistance of water flow, large water transfer capacity, reduce energy consumption.

4. Good corrosion resistance, the inner and outer layers of the pipe are plastic layers, with the same excellent corrosion resistance as plastic pipes.

5. Light weight, easy loading and unloading transportation.

6. Electrofusion connection, construction is fast and convenient, joints do not leakage.

7. Due to the structure of copper-plastic two materials composite and become, overcoming the rapid stress cracking phenomenon of plastic pipes.

8. Good anti-wear performance, under normal use, service life of 50 years.
