Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant steel pipe technology, specifically to a corrosion-resistant structure on the surface of a steel pipe. Background Technology

[0002] Steel pipes, as an important material widely used in construction, industry, transportation and other fields, are classified into round, square, rectangular and special-shaped steel pipes according to their cross-sectional shape; and into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes according to their material. Their corrosion resistance in various environments is crucial. In actual use, steel pipes are often subjected to corrosion by various corrosive media, such as humid air, acid and alkali solutions, salt spray, etc., which not only affects the service life of steel pipes, but may also lead to safety hazards. Therefore, it is necessary to carry out corrosion-resistant treatment on steel pipes.

[0003] Traditional anti-corrosion treatments for steel pipe surfaces mainly include painting, galvanizing, and nickel plating. However, during long-term use, paint is prone to peeling off and requires regular maintenance. At the same time, a single coating cannot provide comprehensive protection against corrosion. The anti-corrosion protection structure of the steel pipe is insufficient, and its anti-corrosion protection capability is relatively average. Furthermore, the protective structure is not convenient to disassemble and assemble, and the installation tightness is not good enough. Therefore, we propose a corrosion-resistant structure for the surface of steel pipes to solve the above problems. Utility Model Content
