316 Stainless Steel Welded Pipes

316 Stainless Steel Welded Pipes

A 316 stainless steel welded pipe is made from molybdenum-alloyed 316L strip by longitudinal welding and resists pitting corrosion better than 304.

It is used on lines carrying chlorides or aggressive fluids in seawater, pool, chemical, pharmaceutical and food processes. Diameter, wall thickness and length are confirmed against stock.
