Hello everyone! needPVC double wall corrugated pipe? For PVC double wall corrugated pipes, please choose Henan Ouyuan Building Materials Co., Ltd. Let's take a look belowIntroduction to PVC double wall corrugated pipe.

PVC double wall corrugated pipe: a pipe with a double layered structure, with a smooth and flat inner wall and equidistant outer wall arranged in a trapezoidal hollow structure. Nominal diameter (DN): The nominal diameter of a pipe, divided into two types: inner diameter series and outer diameter series, which are executed simultaneously. Circumferential bending stiffness: a measure of the ability of a pipeline to resist circumferential deformation.

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 of PVC double wall corrugated pipe:

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.
