Description

Technical Field

[0001] This utility model relates to the field of pipe elbow technology, and in particular to a wear-resistant polyethylene pipe elbow. Background Technology

[0002] Pipeline transportation of granular materials is more efficient and less costly than vehicle transportation. Polyethylene pipes and composite pipes made of polyethylene are widely used because their wear resistance is 5 to 6 times greater than that of steel pipes. However, the elbows of existing pipes used for granular transportation are made using a straight core-pulling process in injection molding. As a result, the outer pipe wall outline on the cross-section of the center line is an arc, while the inner pipe wall outline is at a 90 or 135 degree angle.

[0003] Currently, existing polyethylene pipe elbows experience significant wear after prolonged use, which negatively impacts the conveying of granular materials, reduces their service life, and lowers the overall effectiveness of the device. Therefore, we propose a wear-resistant polyethylene pipe elbow to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant polyethylene pipe elbow to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wear-resistant polyethylene pipe elbow includes a pipe elbow body, with connecting flanges fixedly connected to both ends of the pipe elbow body. A fiber layer is fixedly connected to the outer surface of the pipe elbow body, an anti-corrosion layer is fixedly connected to the outer surface of the fiber layer, a waterproof layer is fixedly connected to the outer surface of the anti-corrosion layer, a flame-retardant layer is fixedly connected to the outer surface of the waterproof layer, and a wear-resistant layer is fixedly connected to the outer surface of the flame-retardant layer.

[0007] In a further embodiment, a production mark is fixedly connected to the outer surface of the wear-resistant layer, and a protective film is fixedly connected to the outer surface of the production mark.

[0008] In a further embodiment, the fiber layer is composed of collagen fibers, the flame-retardant layer is composed of polyvinyl chloride, and the wear-resistant layer is composed of melamine resin.

[0009] In a further embodiment, a sealing gasket is fixedly connected to each of the two connecting flanges on their opposite sides, and a set of annularly arranged connecting holes is provided on both the opposite sides of the two sealing gaskets and the opposite sides of the two connecting flanges.

[0010] In a further embodiment, the anti-corrosion layer is composed of nylon fibers, and the waterproof layer is composed of fiber felt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device enhances the wear resistance of the pipe elbow by incorporating a wear-resistant layer and a fiber layer to improve its flexibility, thereby strengthening its structural strength and extending its service life. A flame-retardant layer prevents the pipe elbow from catching fire and hinders the spread of flames if combustion occurs. The combination of a waterproof layer and a protective layer enhances its corrosion resistance, improving its overall performance. Finally, the inclusion of connecting flanges facilitates connection and reduces installation time. Attached Figure Description

Next, by setting the flame-retardant layer 5, the pipe elbow body 1 can be prevented from spreading during combustion. Finally, by setting the waterproof layer 4 and the anti-corrosion layer 3, the corrosion resistance of the pipe elbow body 1 is improved, thereby extending the service life of the pipe elbow body 1.
