Stable corrosion-resistant stainless steel pipe

Abstract

The invention relates to the technical field of stainless steel pipes, in particular to a stable corrosion-resistant stainless steel pipe which comprises a first pipe body and a second pipe body. An extension pipe is installed on the right side of an inner cavity of the second pipe body, fixing plates are installed at the upper portion and the lower portion of the left end of the extension pipe, through holes are formed in the surfaces of the fixing plates in a penetrating mode, and connecting blocks are installed on the upper side and the lower side of an inner cavity of the first pipe body. According to the stable corrosion-resistant stainless steel pipe, the steel pipes can be fixed and aligned in an auxiliary mode before welding, other devices or equipment does not need to be used, the connecting steps are simplified, and the problems that in a current welding process, the steel pipes need to be fixed and aligned through other devices or equipment, the connecting steps become tedious, the efficiency is low, and fixing is not stable enough are solved; and meanwhile, the stable corrosion-resistant stainless steel pipe has a corrosion-resistant protection function, the service life is effectively prolonged, and the situation that the service life of the stainless steel pipe is greatly shortened due to the fact that the stainless steel pipe is corroded easily is avoided.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipes, in particular to a stable corrosion-resistant stainless steel pipe. Background technique [0002] Stainless steel pipe is an economical section steel and an important product in the iron and steel industry. It is widely used in the national economy. Because the steel pipe has a hollow section, it is most suitable for the transportation of liquids, gases and solids; at the same time, compared with the round steel of the same weight, the steel pipe has a large section coefficient and a high bending and torsional strength, so it has also become a variety of mechanical and architectural structures. important material. Structures and components made of stainless steel pipes have a larger section modulus than solid parts when the weight is equal, so stainless steel pipes themselves are a kind of economical section steel that saves metal, and it is an important component of high-efficienc...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a stable corrosion-resistant stainless steel pipe, which can assist in fixing and aligning the steel pipe itself before welding, and simplifies the connection steps, solving the need for other devices or equipment to fix and align the steel pipe in the welding process , resulting in cumbersome connection steps resulting in low efficiency and insufficient fixation. At the same time, the steel pipe has a corrosion-resistant protection function and avoids the situation that the stainless steel pipe is easily corroded and the service life is shortened.
