PSP Composite Pipe
The main materials used are polyethylene and stainless steel.

The inside and outside are polyethylene layers and stainless steel layer is in the middle. The technology ensures that the whole structure of the composite pipe is seamless.

It uses a special technology to bond the two plastic layers and steel layer together in order to strengthen the whole pipe.

1. Characteristics:
a) The intensity, rigidity and anti-concussion outstrip that of pure plastic pipes,
b) Double surface antisepsis can endure higher temperature and various chemical materials,
c) Low diathermancy, no need to coat it to maintain the energy,
d) Isolates oxygen and other gases and liquids from penetrating inside, prevents contamination in the pipe system,
e) Smooth inside surface, not accumulate dirt, water pressure loss is less than steel pipes by 30%,
f) Static-resistance, toroidal screen,
g) Use low cost electric-heat melting fittings to connect with various specifications available,
h) Light, easy to ship and install,
i) Reliable, workable for 70 years in normal circumstance,
j) Innocuous and environment friendly.
k) Self-shown tracer: it can be traced by magnetic metal detector, and no need to bury other tracer or protection marking, avoids excavation damage, provides convenience for repair and maintenance.
2. Broad application:
Chemical, Oil field, Mining, Textile, printing, dyeing and paper making, Building, Agriculture, Shipbuilding, water supply, drainage, gas, thermoelectricity engineering, food and liquid conveying in industry which is recommended by State Ministry of Construction and China Association for Engineering Construction Standardization, it’s the preferred pipe for urban rural water supply in 21st century.
