Welded stainless steel pipe
Welded stainless steel pipe is made by forming plate or strip and joining its edges along a seam, followed by finishing and inspection appropriate to the manufacturing route and product specification. The weld seam distinguishes it from seamless stainless pipe; it does not automatically indicate lower quality or poorer corrosion resistance. Selection should define grade, welding process and quality controls, heat-treatment condition, dimensions, seam examination, fabrication requirements, and the applicable project specification because service performance depends on the complete product definition.
Application and duty
Lines where welded stainless pipe suits the project specification and seam-quality plan; grade, manufacturing route, and examination requirements must be defined before purchase.
