SRTP is short for Steel-wire Reinforced Thermoplastics (PE) composite-Pipe.

It is a new type of double-face anti-corrosion pressure conduit made of net frame wound with left & right spinning high-strength steel wires as the reinforcement and high density polyethylene (HDPE) as the basal body, by using high-performance cementing resin layer to closely connect the wire net frame with both inner & outer HDPE layers and continuous forming on the extruding production line.

It has many advantages, such as high strength, good rigidity, large circular rigidity, crepe-resistant, small linear expansion coefficient, long lifetime, etc.

- It can be used for connection with all sizes of pipes of SDR series.
- It can be used for connection of pipes of same kind, same class but different number (different density, different melting index, different colors).
- Reliable connection ability, the strength of joint is high, gas sealing property is good, melting property is very stable.
- Buried hidden screw electric heat wire can effectively resist oxidization and erosion so as to guarantee stability of welding property.
- It is not easily affected by ambient temperature and man-made factors.
- Welding technology is rather simple. It is easy to operate, construction is rather convenient.
