WELDED Stainless Steel Tube

Stainless steel welded pipes are commonly used steel pipes or steel strips that are welded after being rolled by a unit and a die. The production process of welded steel pipes is simple, with many varieties and specifications, less equipment investment, and generally lower strength than seamless steel pipes. With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of welded steel pipes are increasing. In more and more fields, especially heat exchange equipment pipes and decorations Pipes, medium and low pressure fluid pipes, etc. have replaced seamless steel pipes.


How To Classify the Welded Stainless Steel Tube?

According to welding technology, it can be divided into automatic welding and manual welding. Automatic welding generally uses submerged arc welding and plasma welding; manual welding generally uses argon arc welding.

According to the weld form, it can be divided into straight seam welded pipe and spiral welded pipe.

According to the application, it can be divided into general welded pipes, heat exchanger pipes, condenser pipes, deep well pump pipes, electric welded thin-walled pipes, etc.

What Is the Principle Of the Welded Stainless Steel Tube?(American Standards)

  1. The American Standard is recognized all over the world, and ASTM A312(M) and A269(M) are generally implemented. M here stands for metric system, that is, the unit is measured in mm. If there is no suffix, it will be measured in imperial units.

  2. TP of TP304 stands for tube and pipe. Generally, pipe refers to large tube and tube refers to small tube, which is mainly used inside the equipment.

  3. The ASME standard adopts the ASTM standard equivalently.

Where Can We Use the Welded Stainless Steel Tube?

Petroleum industry pipes, pharmaceutical industry pipes, food industry pipes, boiler heat exchange pipes, industrial pipes, dairy products, beer and beverage industries, and machinery industries. Stainless steel welded pipes are also used in the power plant and paper mill industry.
