PP Spiral Winding Pipe

PP inner rib reinforced spiral winding pipe is made of polypropylene (PP) as the main raw material, which adopts a one-step molding process to extrude a specific trapezoid shape of the inner tube through the automatic extrusion equipment, and then composite structural wall pipe by winding technology through the molding machine.

Product Features

  • 1. High ring stiffness: Advanced production technology, high rigidity of imported raw materials, and solid structural principles in the production process ensure that the pipe has sufficient strength and other physical properties.
  • 2. Anti-aging: Good heat resistance, anti-ultraviolet performance to prevent product aging,more than 50 years service life;
  • 3. High impact resistance,good ring flexibility;
  • 4. Compared with steel pipe and cement pipe, it has strong abrasion resistance, light weight and convenient connection;
  • 5. Good hydraulic performance: smooth inner wall, small resistance coefficient, fast flow rate, not easy to scale;
  • 6.Low maintenance cost: only need to be partially cleaned and dredged once 8-10 years, cement pipe need to be dredged once 2-3 years, greatly reducing the subsequent maintenance costs.

Application Areas

1. Unpressurized underground buried industrial sewage pipe;

2. Municipal drainage sewage pipes;

3. External drainage of buildings;

4. Rainwater collection and Domestic sewage discharge;

5. Expressway construction.
