Plastic coating steel-plastic composite products.
Plastic composite pipe steel and steel pipe,
Connecting pipe and fittings can be taken
Screwed, grooved, flanged, socket connection and welding. Plastic pipe while maintaining the pipe mechanics
Good performance, high compressive strength, impact resistance and other advantages; they have plastic pipe corrosion-resistant, wall smooth, not scaling
And so on.  Plastic composite pipe national standards has been formed by the three met to discuss approval
Draft, is preparing to report the Standards Commission and GB steel will. Because the national standard "plastic composite pipe" is in
CJ / T136-200
7 "Water Lining Plastic composite pipe" and
CJ / T120-
Develop "Water plastic composite pipe," based on 2007 base
The technical parameters are not changed, now the national standard "plastic composite pipe" and
CJ / T136. The reason   honor qualification
