Performance Characteristics
Unique structure, high strength, smooth inner wall, low friction resistance, large flow rate, no need for concrete foundation, light weight, easy handling and installation, and fast construction; Rubber ring socket connection, reliable method, easy to ensure construction quality; Flexible interface. Strong ability to resist uneven settlement;
Good anti leakage effect and can withstand erosion from various chemical media; There is no scaling inside the pipe, and there is basically no need to dredge it. The buried service life is over 50 years.
production process
PVC double wall corrugated pipe is mainly made of rigid polyvinyl chloride. The PVC double wall corrugated pipe is extruded from the inside and outside, molded in one go, with a smooth inner wall and a trapezoidal corrugated outer wall. A hollow plastic pipe is sandwiched between the inner and outer walls.
Application field
