сталь и пластиковые композитные трубы производственной линии

Large diameter steel reinforced polyethylene spiral corrugated pipe is developed by Goldstone based on the normal polyethylene corrugated pipe. The innovatied reinforced corrugated pipe provide the steel reinforced structure to definitely increase the ring stiffness of the corrugated pipe.In the mean time, the weight of the pipe has been obviously reduced. The pipe diameter ranged from 300 mm to 2400 mm, which gives the large diameter pipe the better ring stiffness more than SN8. The pipe has innovated three layers wall structure: The steel reinforced layer is in the middle structure to provide the high stiffness, and either the inner layer or outer layer is formed by high-density polyethylene that protects the pipe out of the corrosive; And there is a super bond medium between steel and polyethylene which integrate them into one piece.
