A stainless steel welded pipe is produced by roll-forming stainless strip or plate into a tube and fusing the seam with TIG, plasma, laser or high-frequency ERW welding. Modern welding and in-line annealing give an SS welded pipe excellent dimensional accuracy, a smooth bore and corrosion resistance close to that of seamless pipe – at a much lower price per kg.
As a reliable SS ERW pipe supplier, Innovative Corporation stocks welded pipes in SS 304, SS 316 and SS 202 from ½" to 12" NB, plus large-diameter EFW pipes up to 48" OD on order.

SS ERW pipe is a stainless steel pipe made by electric resistance welding of a rolled strip. It is economical and widely used for water, structural and general process piping.
For most low and medium pressure applications, yes. Design codes apply a weld joint factor (typically 0.85, or 1.0 with full radiography) when calculating pressure ratings for welded pipe.
Welded SS 304 pipe is generally the most economical industrial SS pipe. See the SS pipe price list for indicative rates.
