Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anticorrosive steel pipe, and particularly relates to an anticorrosive steel pipe with a heat dissipation structure. BACKGROUND

[0002] Anticorrosive steel pipe refers to a steel pipe that is processed through an anticorrosive process and can effectively prevent or slow down chemical or electrochemical reactions that cause corrosion during transportation and use. According to statistical data in China, the direct economic loss caused by steel pipe corrosion is more than 280 billion yuan per year. Anticorrosive steel pipe base materials include spiral pipes, straight-seam pipes, and seamless pipes, which are widely used in long-distance water transportation, petroleum, chemical industry, natural gas, heat supply, sewage treatment, water source, bridge, steel structure, and marine water transportation and piling pipeline engineering fields in China. Anticorrosive steel pipes need to be cooled in time according to needs during use.

[0003] For example, patent number CN221548001U discloses an anticorrosive steel pipe with a heat dissipation structure, which includes a steel pipe body, a first anticorrosive layer, and a second anticorrosive layer. The inner wall of the steel pipe body is provided with the first anticorrosive layer. The outer wall of the steel pipe body is provided with the second anticorrosive layer through an adhesive. The outer wall of the second anticorrosive layer is provided with an anticorrosive coating. The outer wall of the anticorrosive coating is provided with a plurality of heat dissipation fins. The heat dissipation fins are internally provided with a plurality of heat dissipation holes. The device increases the anticorrosive effect and mechanical properties by adding the first anticorrosive layer and the anticorrosive coating. In addition, the second anticorrosive layer is made of glass steel. The glass fiber is used as the skeleton. Synthetic resin (phenolic plastic, epoxy resin, and polyester resin) is used as the muscle. They are integrated into one. The device has the advantages of light weight, high strength, resistance to burning, good insulation performance, and corrosion resistance. However, the interior of the anticorrosive steel pipe is not provided with heat dissipation fins, so it cannot dissipate the heat of the transmission medium in time.

[0004] In view of this, the present application provides an anticorrosive steel pipe with good heat dissipation performance. UTILITY MODEL CONTENTS
