Abstract

The invention relates to a steel pipe. The steel pipe comprises a steel pipe body and further comprises a protective sleeve and a buffer piece, wherein the buffer piece comprises a first buffer layer, a spring and a second buffer layer, the protective sleeve is arranged on the steel pipe body in a sleeve mode, the first buffer layer is arranged on the outer side wall of the steel pipe body, the second buffer layer is arranged on the inner side wall of the protective sleeve, one end of the spring is connected to the first buffer layer, and the other end of the spring is connected to the second buffer layer. According to the steel pipe, the problem that the steel pipe is prone to deformation or damage can be solved.

Description

technical field [0001] The present application relates to the field of steel pipes, in particular to a steel pipe and its processing technology. Background technique [0002] Steel pipe is a kind of steel with a hollow section, whose length is much longer than the diameter or circumference. According to the cross-sectional shape, it can be divided into circular, square, rectangular and special-shaped steel pipes, which can be used for transporting fluid and exchanging heat. [0003] The Chinese patent with the publication number CN105937673A discloses a small-diameter precision steel pipe, including: a steel pipe body, a first composite coating, a high-temperature wear-resistant composite coating, a second composite coating, and an anti-corrosion and wear-resistant composite coating. The inner surface of the steel pipe is provided with the first composite coating, and the outer surface of the steel pipe body is sequentially provided with the high-temperature wear-resistant c...
