Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to an antioxidant winding pipe. Background Technology

[0002] Spiral wound pipe is a type of pipe or protective sleeve made through a spiral winding process. It is mainly made of high-density polyethylene and is formed by spiral winding and welding. It has a smooth inner wall and a diameter of up to 3 meters or more.

[0003] In the prior art, a search revealed a Chinese patent that discloses "An Antioxidant Long-Life Winding Tube," with application number "202322514219.0." This patent mainly includes a winding tube body, which consists of an inner tube, a first antioxidant layer, an outer protective tube, a second antioxidant layer, and a corrosion-resistant layer. The outer side of the winding tube body is provided with two first retaining seats, two second retaining seats, two third retaining seats, and four crossbars. Each of the two first retaining seats is connected to two of the crossbars, and each of the two third retaining seats is connected to the other two crossbars. Each of the two first retaining seats and one of the second retaining seats has two locking bolts, and each of the two third retaining seats and the other second retaining seat has two screw holes adapted to the locking bolts. Although the aforementioned patent can improve the overall corrosion resistance and oxidation resistance through the corrosion-resistant layer, outer protective tube, first antioxidant layer, and second antioxidant layer, and the first retaining seats, second retaining seats, crossbars, and third retaining seats can shield and protect the winding tube body, thereby extending the service life of the winding tube body. However, the structure supporting the spiral wound pipe, including the first and second clamps, connecting sleeve, connecting bolts, and locking bolts, is complex. The use of connecting bolts and locking bolts also makes installation cumbersome and reduces efficiency. Especially during underground installation, the first and second clamps, connecting sleeve, connecting bolts, and locking bolts require corrosion-resistant treatment, increasing costs and making it uneconomical. Therefore, this invention provides an anti-oxidation spiral wound pipe to solve the problems mentioned in the background. Utility Model Content

The overall protective effect of the protective strip improves the spiral wound pipe's corrosion resistance and oxidation resistance.

[0005] To achieve the above objectives, an antioxidant spiral wound tube is provided, comprising a spiral wound tube body, a protective strip spirally wound on the outside of the spiral wound tube body, and a plurality of vertical ribs clamped on the outside of the protective strip. The vertical ribs are C-shaped structures with openings, and the opening structures of adjacent vertical ribs are arranged opposite to each other.

[0006] The protective strip comprises, from the inside out, an adhesive layer, a buffer layer, a base layer, and an anti-oxidation layer.
