Stainless steel welded tube is a type of tubing made from stainless steel that has been welded together at the seam. It is commonly used in applications where high strength, durabilité, and resistance to corrosion are required, such as in the construction of pressure vessels, échangeurs de chaleur, and piping systems.The manufacturing process for stainless steel welded tubes involves first forming a flat strip of stainless steel into a tube shape. The edges of the strip are then heated to a high temperature and fused together using an electric current or a high-energy beam. This process creates a strong, continuous seam along the length of the tube.
Stainless steel welded tube is available in a variety of sizes, wall thicknesses, and grades of stainless steel, including austenitic, ferritic, and duplex grades. The choice of grade and wall thickness will depend on the specific application and the required mechanical properties of the tubing.
