PVC-U corrugated pipe

Performance characteristics

Unique structure, high strength, smooth inner wall, low friction resistance, large circulation, the foundation does not need to be a concrete foundation, light weight, convenient transportation and installation, and quick construction; rubber ring socket connection, reliable method, easy construction quality; flexible interface . Strong ability to resist uneven settlement;

The anti-leakage effect is good, and it can withstand the erosion of a variety of chemical media; there is no scaling in the pipe, basically without dredging, and the buried service life is more than 50 years.

Production Process

The pvc double-wall corrugated pipe is made of hard polyvinyl chloride as the main raw material. The pvc double-wall corrugated pipe is extruded from the inside and the outside respectively, and formed at one time. The inner wall is smooth and the outer wall is trapezoidal corrugated. The inner and outer walls are sandwiched by hollow plastic Pipe.
