Description

Technical Field

[0001] The utility model application relates to the technical field of PP pipes, specifically a PP pipe with a pressure-resistant and oxidation-resistant composite layer. Background Art

[0002] PP pipe is a non-toxic, hygienic, high temperature resistant and recyclable pipe. It is corrosion-resistant, wear-resistant, scale-resistant, reduces vibration and noise, prevents freezing and cracking, prevents condensation, has low heat loss, is easy to install and has a long service life. It is widely used in indoor hot and cold water supply systems and heating systems in buildings. There are three connection methods during installation: welding, end edge welding, and connecting pipes made of different materials.

[0003] When in use, PP pipes are limited by their material, resulting in limited compressive performance. PP pipes laid outside the painting room are exposed to the outside for a long time and are easily hit by foreign objects. They are also exposed to the sun for a long time, which causes them to become brittle and crack due to oxidation after long-term use, and they are prone to deformation or cracking after being compressed. Summary of the invention

[0004] In order to solve the problem that the existing PP pipe has poor compression resistance and oxidation resistance when used outdoors, the utility model provides a PP pipe with a compression-resistant and oxidation-resistant composite layer to solve the above-mentioned problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A PP pipe with a compression and oxidation resistant composite layer comprises a pipe main body, wherein the pipe main body comprises a plastic pipe body, a heat-insulating sleeve, a compression-resistant hard support ring, a hard-resistant connecting piece and an insulating compression-resistant and oxidation-resistant sleeve. The outer surface of the plastic pipe body is fixed with a heat-insulating sleeve, a plurality of compression-resistant hard support rings are equidistantly fixed on the outer surface of the heat-insulating sleeve, a plurality of hard-resistant connecting pieces are equidistantly fixed between every two of the compression-resistant hard support rings, and the outer surfaces of the compression-resistant hard support rings and the hard-resistant connecting pieces are fixed with insulating compression-resistant and oxidation-resistant sleeves.

[0007] Furthermore, the pipe body also includes an anti-corrosion and anti-bacterial coating and an anti-corrosion and anti-oxidation coating. The inner surface of the plastic pipe body is coated with an anti-corrosion and anti-bacterial coating, and the outer surface of the insulating, pressure-resistant and anti-oxidation sheath is coated with an anti-corrosion and anti-oxidation coating.

[0008] Furthermore, each of the compression-resistant rigid support rings is configured as a ring shape that matches the heat-insulating sleeve layer, and each of the compression-resistant rigid connecting pieces is configured as an arc shape that matches the compression-resistant rigid support ring.

[0009] Furthermore, each of the compression-resistant rigid support rings and the compression-resistant connecting sheet has an equal thickness, and each gap formed by the compression-resistant rigid support ring and the compression-resistant connecting sheet is filled with reinforcing glue.

[0010] Furthermore, the thickness of the compression-resistant rigid support ring and the anti-rigid connecting piece is greater than the thickness of the anticorrosive and antibacterial coating, and the thickness of the compression-resistant rigid support ring and the anti-rigid connecting piece is less than the thickness of the plastic pipe body.

[0011] Furthermore, the thickness of the plastic pipe body is equal to the thickness of the thermal insulation jacket, and the thickness of the thermal insulation jacket is equal to the thickness of the insulating, compression-resistant and oxidation-resistant jacket.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, the anti-corrosion and anti-oxidation properties of the pipe body can be improved by combining the anti-corrosion and anti-bacterial coating with the anti-corrosion and anti-oxidation coating, and the combination of the compression-resistant rigid support ring and the compression-resistant rigid connecting piece can effectively improve the compression resistance of the pipe body, solving the problem of poor compression resistance and anti-oxidation properties of the existing PP pipe when used outdoors, and greatly improving the service life of the PP pipe when used outdoors, as well as the safety during use.
