Difference Between Seamless And Welded Pipes (Stainless Steel 304 Seamless Pipes)

Stainless Steel 304 Seamless Pipes

Stainless Steel 304 Seamless Pipes

Stainless steel 304 Seamless pipes are made from solid steel sheets or bars that are shaped into solid round shapes called “billets” and then heated and cast over a form like a piercing rod to make a hollow tube or shell.

Stainless Steel 304 Welded Pipes

A steel strip or steel plate is used to make these pipes. The steel plate is bent first, then welded into round, square, and other shapes throughout the manufacturing process. SS 304 Welded steel pipe has high production efficiency, cheap cost, and material saving properties. Aviation, aerospace, energy, electronics, automobiles, the light industry, and other industries have all used it. In an acidic atmosphere, it has high corrosion resistance.

Difference between Stainless Steel 304 seamless and Stainless Steel 304 welded pipes

Welded SS 304 pipe was traditionally thought to be intrinsically weaker due to the presence of a weld seam. This perceived structural fault was absent in stainless Steel 304 Seamless Pipes, making it safer. While SS 304 welded pipe does feature a seam that makes it potentially weaker, production techniques and quality assurance procedures have both evolved to the point that SS 304 welded pipe will operate as expected when tolerances aren’t exceeded. While the obvious benefit is obvious, one criticism of seamless piping is that the rolling and stretching operation results in an irregular wall thickness when compared to the more accurate thickness of steel sheets going for welding. Welded SS 304 steel pipes can withstand 20 percent less working pressure than seamless SS 304 steel pipes. Because of the raw material, production equipment, and processes, the cost of SS 304 seamless steel pipes is usually higher than that of SS 304 welded steel pipes. Stainless steel 304 seamless pipes have a higher pressure capacity and strength than welded stainless steel 304 pipes.
