Abstract

The invention discloses an antirust coal gas steel pipe, which comprises a vehicle frame pipe body, a protection reinforcing outer layer and a protection reinforcing inner layer, wherein the protection reinforcing outer layer is connected with the outer side of the vehicle frame steel pipe body, the protection reinforcing inner layer is connected with the inside of the vehicle frame steel pipe body, the protection reinforcing outer layer is provided with a waterproof protection film, and the protection reinforcing inner layer is provided with a scratch-resistant protection film. Through adopting the mode, the anti-rust coal gas steel pipe has the advantages of waterproof and antirust function, high stability and long service life.

Description

technical field [0001] The invention relates to the field of steel pipes, in particular to an antirust gas steel pipe. Background technique [0002] Seamless steel pipe is a round, square, or rectangular steel with a hollow section and no seams around it. Seamless steel pipes are made of steel ingots or solid tube blanks that are perforated into capillary tubes, and then made by hot rolling, cold rolling or cold drawing. The seamless steel pipe has a hollow section and is widely used as a pipe for conveying fluid. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same. It is an economical cross-section steel and is widely used in the manufacture of structures. parts and mechanical parts. [0003] Bicycle frames need to use seamless steel pipes. General steel pipes have poor waterproof performance, are prone to rust, and have a short service life. Contents of the invention [0004] The techn...
