Abstract

The invention provides a composite stainless steel tube. The composite stainless steel tube comprises a hollow stainless steel inner tube and an aluminum alloy outer tube arranged on the hollow stainless steel inner tube in a sleeved mode. The inner wall of the hollow stainless steel inner tube is provided with an anti-corrosion coating, and the outer wall of the aluminum alloy outer tube is provided with a wear-resistant coating. The composite stainless steel tube has the advantages that the anti-corrosion coating can prevent the stainless steel inner wall from being corroded; the total weight is reduced and the weldability is improved due to the aluminum alloy outer tube; the wear-resistant coating has the wear resistance.

Description

technical field [0001] The invention relates to a composite stainless steel pipe, which belongs to the technical field of stainless steel products. Background technique [0002] Stainless steel pipe is a hollow elongated round steel material, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc. [0003] The inner wall of the existing stainless steel pipe is easily corroded, and the maintenance workload is heavy. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a composite stainless steel pipe. [0005] Th...
