Embodiment

[0039] Such as figure 1 and figure 2 As shown, a FRPO composite reinforced hollow winding pipe includes a winding pipe body formed by winding a rectangular pipe 1. The inner wall and the outer wall of the winding pipe body are respectively provided with a wear-resistant layer 3 and a compression and stretching layer 4. The grinding layer 3 is a modified polyolefin wear-resistant material, the compressive and tensile-resistant layer 4 is a polypropylene material, and the material of the rectangular tube 1 includes polypropylene material, nanometer material, glass fiber material and compatibilizer.

[0040] In another embodiment, the smoothness of the inner wall and the outer wall of the winding pipe body is Ra0.012-Ra0.009.

[0041] In another embodiment, such as figure 2 As shown, the inside of the winding pipe body is respectively provided with adhesive reinforcing ribs 2 between two adjacent rectangular pipes 1 .

[0042] In another embodiment, the raw material of the r...

Abstract

The invention discloses an FRPO composite reinforced hollow winding pipe. The FRPO composite reinforced hollow winding pipe comprises a winding pipe body formed by winding rectangular pipes, the smoothness of the inner wall and the outer wall of the winding pipe body is Ra0.012-Ra0.009, the inner wall and the outer wall of the winding pipe body are provided with a wear-resisting layer and a compression-resisting and stretching-resisting layer respectively, and bonding reinforcing ribs are arranged at positions, located between every two adjacent rectangular pipes, inside the winding pipe body.The composite reinforced hollow winding pipe has the advantages of high impact resistance, high strength, high wear resistance, super corrosion resistance, light weight, simplicity and convenience ininstallation, large through-flow, long service life and the like.

Description

technical field [0001] The invention relates to the field of drainage pipes, in particular to an FRPO composite reinforced hollow winding pipe and a preparation method thereof. Background technique [0002] At present, in urban drainage, industrial drainage and farmland drainage projects, commonly used pipes include cement pipes, polyethylene plastic-steel winding pipes, HDPE steel belt reinforced corrugated pipes, and glass steel pipes. The flexibility and chemical corrosion resistance of these pipes are generally higher. Poor, the service life is insufficient, and it is not hygienic and environmentally friendly. Contents of the invention [0003] In view of the above problems, the present invention provides a FRPO composite reinforced hollow winding pipe, and provides a preparation method of the winding pipe, the winding pipe has high impact resistance, high strength, high wear resistance, super corrosion resistance, light weight, easy installation Simple, large flow ra...
