Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a corrosion-resistant stainless steel pipe. Background Technique

[0002] Stainless steel pipes are a kind of hollow long round steel, mainly widely used in industrial pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments, etc., as well as mechanical structure parts. 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 in furniture, kitchen utensils, etc. Annealed stainless steel pipes with an inner diameter of more than 6.0 mm and a wall thickness of less than 13 mm can use a W-B75 type Vickers hardness tester, which is very fast and simple to test, and is suitable for quickly and non-destructively inspecting stainless steel pipes for compliance. For stainless steel pipes with an inner diameter greater than 30 mm and a wall thickness greater than 1.2 mm, a Rockwell hardness tester is used to test the HRB and HRC hardness. For stainless steel pipes with an inner diameter greater than 30 mm and a wall thickness less than 1.2 mm, a superficial Rockwell hardness tester is used to test the HRT or HRN hardness. For stainless steel pipes with an inner diameter less than 0 mm and greater than 4.8 mm, a special Rockwell hardness tester for pipes is used to test the HR15T hardness. When the inner diameter of the stainless steel pipe is greater than 26 mm, the Rockwell or superficial Rockwell hardness tester can also be used to test the hardness of the inner wall of the pipe. Stainless steel exports are an important part of China's export economy and play an important role in driving China's economic growth. However, judging from the current situation of China's stainless steel foreign trade, China's stainless steel exports have encountered relatively large resistance.

[0003] The application number is CN202222336970.1, which discloses a corrosion-resistant stainless steel pipe, relating to the technical field of stainless steel pipes. In order to solve the problem that a small amount of objects will remain inside the steel pipe, and with the passage of stacking time, some substances with strong corrosiveness will be formed, increasing the probability of the steel pipe being corroded. An anti-corrosion inner block is arranged on one side inside the stainless steel pipe main body, and the anti-corrosion inner block is fixedly connected with the stainless steel pipe main body through a card slot, and there are two or more stainless steel pipe main bodies; an impact-resistant filling inner block is arranged in the middle of the anti-corrosion inner block, and the impact-resistant filling inner block is fixedly connected with the stainless steel pipe main body through a card slot, and inner fixing squares are arranged on both sides inside the impact-resistant filling inner block, and the inner fixing squares are welded to the stainless steel pipe main body.

[0004] Although the above-mentioned utility model has more than two stainless steel pipe bodies; impact-resistant filling inner blocks are arranged at the middle positions of the corrosion-resistant inner blocks, and the impact-resistant filling inner blocks are fixedly connected to the stainless steel pipe bodies through card slots, and inner fixing squares are arranged on both sides inside the impact-resistant filling inner blocks, and the inner fixing squares are welded to the stainless steel pipe bodies, there is a deficiency that when the device is in use, there will be risks such as being collided, and at this time, it will have a certain impact on the outer wall damage of the pipe body.

[0005] Therefore, it is necessary to install a protective support component on the outside of the device, so that when using this device, through its component, it can provide a certain protective effect on the pipe body during use. Because of the composition of harder materials, it can avoid situations such as the deformation of the bent pipe caused by extrusion of the pipe body, or reduce the damage caused by impact.
