Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of petroleum machinery, and in particular to spiral wear-resistant belt anti-wear oil pipe. Background Technology
[0002] Oil pipelines are used to transport large quantities of crude oil or liquid petroleum products. They are mainly used to transport crude oil or petroleum products from oil fields to factories, transfer stations or ports. They are an indispensable part of the petroleum industry, enabling efficient and stable oil transportation and ensuring the smooth operation of oil extraction, processing, transportation and sales.
[0003] Existing oil pipes, such as the anti-corrosion, wear-resistant, and heat-insulating oil pipe disclosed in utility model patent application number 202422280165.0, mainly include heat-insulating oil pipes and heat-insulating couplings. The heat-insulating oil pipes are connected by heat-insulating couplings. The heat-insulating oil pipe includes an outer pipe and an inner pipe. The two ends of the outer pipe are welded to the inner pipe. An oil pipe heat insulation layer is provided between the outer pipe and the inner pipe. The inner pipe has an inner pipe joint that extends out of the outer pipe. The outer wall of the inner pipe has an inner pipe protrusion that protrudes towards the outer pipe. The end of the outer pipe is welded to the inner pipe protrusion. The inner pipe joint is threaded to the inside of the heat-insulating coupling, and the end of the heat-insulating coupling is in contact with the inner pipe protrusion. In use, the heat-insulating coupling is connected to the inner pipes of the two heat-insulating oil pipes. The heat-insulating oil pipe and the heat-insulating coupling are tubular as a whole. The pipe diameter at the heat-insulating coupling is not too large to ensure the smooth installation of the heat-insulating oil pipe and the wrapping material.
[0004] However, most existing oil pipes have poor wear resistance, which easily leads to pipe wear and frequent pipe replacements, resulting in huge economic waste. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a method that enhances the wear resistance of the oil pipe and extends its service life by cladding a wear-resistant strip on the inside of the pipe, thereby avoiding frequent pipe replacements and reducing economic investment.
[0006] This utility model discloses a spiral wear-resistant belt anti-wear oil pipe, which includes a pipe body, a wear-resistant belt, and a nickel-based alloy electroplating layer. The wear-resistant belt is laser-fused onto the inner wall of the pipe body, and the nickel-based alloy electroplating layer is electroplated onto the inner surface of the wear-resistant belt and the pipe body. By setting the wear-resistant belt and the nickel-based alloy electroplating layer, the wear resistance of the pipe body is enhanced, the service life of the pipe body is extended, and the economic investment is reduced.
[0007] Preferably, it also includes a wear-resistant strip, which is spirally laser-clad onto the inner side of the pipe body with a pitch of 70mm; the spiral laser cladding of the wear-resistant strip onto the pipe body enhances the connection between the pipe body and the wear-resistant strip, and the wear-resistant strip protects the inner wall of the pipe body.
[0008] Preferably, the wear-resistant belt is made of a nickel-based alloy containing tungsten carbide. Nickel-based alloys have high strength and certain resistance to oxidation and corrosion at high temperatures, making them very suitable for applications subject to wear and friction.
[0009] Preferably, the wear-resistant belt also has a thickness of ≥0.25mm and a width of ≥8mm.
[0010] Preferably, the wear-resistant strip also has the following properties: it does not fall off after being bent at 140° after wire cutting; it can withstand a CASS salt spray test for no less than 96 hours; and its hardness requirement is no less than 750HV.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a wear-resistant band and a nickel-based alloy electroplating layer, the wear resistance of the pipe body is enhanced, the service life of the pipe body is extended, and economic investment is reduced.

The wear-resistant belt 02 is laser-fused onto the inner wall of the pipe body 01, and the nickel-based alloy electroplating layer 03 is electroplated onto the wear-resistant belt 02 and the pipe body 01. The wear-resistant belt 02 is spirally laser-fused onto the inner side of the pipe body 01, with a pitch of 70mm. The wear-resistant belt 02 is made of a nickel-based alloy containing tungsten carbide. The wear-resistant belt 02 has a thickness greater than or equal to 0.25mm and a width not less than 8mm. During operation, firstly, the wear-resistant belt 02... 2. A spiral laser cladding is applied to the pipe body 01, enhancing the connection between the pipe body 01 and the wear-resistant belt 02. The wear-resistant belt 02 protects the pipe body 01. The nickel-based alloy has high strength and certain resistance to oxidation and corrosion at high temperatures, making it very suitable for applications subject to wear and friction. Through electroplating, a dense and uniform coating can be formed on the surface of the wear-resistant belt 02, ensuring complete coverage of the surface of the wear-resistant belt and the inner wall of the pipe body. This effectively protects the pipe body 01 and the wear-resistant belt 02 from wear and corrosion, further enhancing the wear resistance and corrosion resistance of the wear-resistant belt 02.

During operation, firstly, the wear-resistant belt 02 is spirally laser-fused onto the pipe body 01, enhancing the connection between the pipe body 01 and the wear-resistant belt 02. The wear-resistant belt 02 provides protection for the pipe body 01. The nickel-based alloy exhibits high strength and certain properties at high temperatures. With its strong resistance to oxidation and corrosion, the wear-resistant belt does not fall off after being bent 140° after wire cutting. It can withstand a CASS salt spray test for no less than 96 hours and has a hardness requirement of no less than 750HV. It is very suitable for applications subject to wear and friction. Through electroplating, a dense and uniform coating can be formed on the surface of the wear-resistant belt 02, ensuring that the surface of the wear-resistant belt and the inner wall of the pipe body are completely covered. This effectively protects the pipe body 01 and the wear-resistant belt 02 from wear and corrosion, further enhancing the wear resistance and corrosion resistance of the wear-resistant belt 02.
