Welded stainless steel pipes are formed through crimping and welding a steel plate or strip. They offer a straightforward production process, high efficiency, a wide range of varieties and specifications, and require minimal equipment investment. The primary advantage lies in their cost-effectiveness. However, their overall strength is typically lower compared to seamless steel pipes. Notable methods for stainless steel pipe welding include electric resistance welding (ERW), electric-fusion welding (EFW), submerged arc welding (SAW), longitudinal submerged arc welding (SAWL), and transverse submerged arc welding (SAWH).

Stainless Steel Welded Pipe Production Process
The typical production process of SS welded pipe: Raw material decoiling—flattening—end shearing and welding—loop—forming—welding—removal of inner and outer welding beads—pre-calibration—heat treatment—sizing and alignment—eddy current testing—cutting—hydraulic pressure inspection—pickling—final inspection—packing—shipment.
Â
The raw materials of spiral steel pipe are steel coil, welding wire, and flux. Before forming, the strip steel is leveled, trimmed, planed, surface cleaned, transported, and pre-bent. The weld gap control device is used to ensure that the weld gap meets the welding requirements and that the pipe diameter, misalignment, and weld gap are strictly controlled. After cutting into single steel pipes, the first three steel pipes of each batch must undergo a strict first inspection system to check the mechanical properties, chemical composition, and fusion status of the welds. After the surface quality of the steel pipe and the non-destructive flaw detection are checked to ensure that the pipe-making process is qualified, it will be officially put into production.
