Bimetal composite steel pipe long in service life

Abstract

The invention discloses a bimetal composite steel pipe long in service life. A steel pipe body is included and integrally provided with a first fixing block. The first fixing block is rotationally provided with a protection device. The protection device comprises a first lead screw, a clamp ring, a bolt, wiping cotton and a limiting rod. The first lead screw penetrates through the clamp ring, theclamp ring is provided with the bolt in a sliding manner, accordingly, waterproof and dustproof work can be conducted on the steel pipe, and the situation that since the water and dust make contact with the pipe wall, corrosion is likely to be caused is avoided; and accordingly, the service life of the steel pipe is prolonged, the usage cost is reduced, material waste is reduced, user incomes areincreased, the wiping protection work can be rapidly conducted on the steel pipe, and the situation that the outer wall of the steel pipe is corroded, and the service life of the steel pipe is shortened is avoided. Meanwhile, the situation that the outer wall of the steel pipe makes contact with other substances, and the service life of the steel pipe is influenced is reduced, and accordingly, theservice life of the steel pipe is prolonged. The bimetal composite steel pipe is simple in operation, high in practicability and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of bimetal composite steel pipes, in particular to a bimetal composite steel pipe with long service life. Background technique [0002] Bimetallic composite pipes have high carbon content, impact resistance, low thermal expansion rate, pressure resistance, high temperature resistance, mature installation, and complete specifications; bimetallic composite pipes produced by many manufacturers have been widely used in oil fields, chemicals, electric power and other industrial fields , its scope of application is becoming wider and wider, and the economic, environmental and social benefits it brings are more obvious. [0003] Most bimetallic composite steel pipes are easy to corrode, mainly because the steel pipes cannot be waterproofed and dustproofed, and the contact between water and dust and the pipe wall is easy to cause corrosion, which reduces the service life of the steel pipes, increases the cost of use...

AI Technical Summary

Problems solved by technology

[0003] Most bimetal composite steel pipes are easy to corrode, mainly because the steel pipes cannot be waterproof and dustproof, and the contact between water and dust and the pipe wall is easy to cause corrosion, which reduces the service life of the steel pipes, increases the cost of use, and causes material damage. Waste, which in turn reduces the user's income, and the steel pipe cannot be quickly wiped and protected, resulting in the corrosion of the outer wall of the steel pipe and shortening the service life of the steel pipe. , in the prior art, the operation is complicated, the practicability is weak, and it is not easy to popularize and use. Therefore, we propose a bimetal composite steel pipe with a long service life to solve the above problems
