201 304 316 2205 Stainless Steel Tube Requests | 15 20 32 50mm and Inch Sizes, Welded Square Requirement
Stainless steel tubing is recorded as seamless with round section, 40mm outside diameter and No.1 finish. The actual thickness option reads 0.1–8mm; the body separately lists 0.5–20mm wall thickness.
The title welded-square requirement and its metric or inch size list are not established by those round seamless fields. Agree section geometry, manufacturing route, exact outside dimensions and wall before ordering. A shape list mentioning square and rectangle does not resolve the selected product.
For industrial construction, specify grade, length and inspection acceptance. The source includes 2205 among many grades but supplies no selected chemistry, pressure rating or dimensional drawing. Request material and route documentation rather than inferring duplex performance or size equivalence from title labels.
