Stainless steel welded pipe is made by rolling stainless steel strip or sheet into a tubular shape and then longitudinally welding it. Welded pipes can be manufactured by either a thermoforming process or a cold forming process. Of the two, cold forming offers a smoother finish and tighter tolerances.
Because of the simpler manufacturing process in welded tube production, the welded tube is usually less expensive than the seamless type. Its benefits are clearly cost-efficient and also can give a longer length than seamless and make fast lead time. It is widely used in Architectural applications, Hypodermic needles, the Automotive industry, Food and beverage industry, the Marine industry and etc.
