Description

Technical Field

[0001] This utility model relates to the field of PE pipe technology, specifically to a high-temperature resistant and wear-resistant PE water supply pipe. Background Technology

[0002] PE plastic water supply pipes are polyethylene plastic pipes with excellent resistance to most domestic and industrial chemicals. They are widely used in water supply and drainage fields such as highways, railways, greening, urban water supply and drainage, and underground irrigation. Water supply pipes are generally laid underground or exposed. However, existing PE pipes have poor high-temperature resistance and protective effects. When transporting hot water, PE pipes often deform under high temperatures, resulting in poor protection and difficulty in coping with various environments. This makes PE pipes easily damaged and reduces their service life.

[0003] Therefore, we propose a new type of PE water supply pipe to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-temperature resistant and wear-resistant PE water supply pipe, as detailed below:

[0005] A high-temperature resistant and wear-resistant PE water supply pipe includes a pipe body, with pipe joints at both ends. Each pipe joint includes an end cap with an annular groove for the pipe body and multiple positioning screw holes corresponding to the annular groove. The pipe body has through holes corresponding to the positioning screw holes. The pipe body and pipe joints are fixed together by positioning bolts corresponding to the positioning screw holes. The pipe body includes a base pipe with a high-temperature resistant layer on its inner side and a braided layer, an anti-aging layer, and a wear-resistant layer sequentially on its outer side.

[0006] Based on the above, the inner side of the high-temperature resistant layer is provided with an antibacterial coating; the antibacterial coating is made of nano-silver coating.

[0007] Based on the above, the material of the high-temperature resistant layer is polyphenylene sulfide.

[0008] Based on the above, the wear-resistant layer is made of polychlorotrifluoroethylene.

[0009] Based on the above, the anti-aging layer is made of nitrile rubber; the anti-aging layer partially enters the braided layer and is bonded to the basic tube.

[0010] Based on the above, the material of the basic tube is PE.

[0011] Based on the above, a sealing ring is also provided inside the annular groove.

[0012] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0013] The high-temperature and wear-resistant PE water supply pipe provided by this utility model has a structural design that not only has good high-temperature resistance and wear resistance, but also good structural strength and antibacterial properties, ensuring the service life of the water supply pipe. The structural design is ingenious and practical. Attached Figure Description
