Description

PVC composite plastic pipe

Technical Field

The utility model relates to a compound plastic pipe technical field specifically is a compound plastic pipe of PVC.

Background

The PVC pipe is widely used in the fields of construction, agriculture and the like at present due to simple processing, low cost and long service life, and is used for conveying fluid or gas. However, in use, the hose is susceptible to wear from a single layer.

In order to enhance the service performance of PVC pipes, double-layer PVC pipes consisting of an inner pipe and an outer pipe have also been proposed, and a mesh-shaped reinforcing layer consisting of fibers is added between the inner pipe and the outer pipe. Traditional double-deck PVC pipe, its enhancement layer direct winding have increased the thickness of body on the outer surface of inner tube on the one hand, and on the other hand is network structure because the enhancement layer is, and network structure's hollow portion stress ratio is concentrated, tears from inside easily when buckling. Therefore, we propose a PVC composite plastic pipe.
