Stainless steel decorative pipe belongs to welded pipe. Cold-drawn seamless steel pipe has hollow section, which is widely used as pipeline for conveying fluid. Compared with solid steel such as round steel, steel pipe has lighter weight when its bending and torsion strength is the same. It is a kind of economic section steel and widely used in manufacturing structural parts and mechanical parts. The whole steel pipe without seams on its surface is produced by rolling, drawing, extrusion or piercing. A round, square, rectangular steel with a hollow section and no seams around it. It is made of perforated ingots or solid billets and then hot-rolled, cold-rolled or cold-drawn.
Welded pipe, also known as welded steel pipe, has simple production process, high efficiency, many varieties and specifications, and less equipment, but its general strength is lower than that of cold-drawn seamless steel pipe. It is a steel pipe made by welding steel plate or strip after coiling and forming.
From the difference between stainless steel decorative pipe and welded pipe, stainless steel decorative pipe should belong to welded pipe.
