201 304 304L 316 316L 310S Welded Stainless Steel Round Pipe Requirements
Welded stainless steel pipe is described with outside diameter 6–530 mm and customer required length. Round section, spiral welding and 2B finish are listed, with other finishes also referenced.
For a 3 or 8 inch request, specify whether the dimension is nominal pipe size or measured outside diameter. Define wall thickness and confirm the exact alloy, particularly 201 or 310S requirements, against the supplied material documentation.
Choose the required welding route and surface rather than assuming every listed alternative is one configuration. Square and rectangular descriptions should be separated from a round pipe order. No fixed diameter variants, pressure class or qualified welding result is supplied. General pipeline engineering or decoration applications do not establish service approval or corrosion compatibility.
