Select the actual tube route and applicable standard before specifying a mirror polished stainless section.

Production route

The title requests welded tube while the detail identifies seamless material. Confirm the actual route and one applicable standard from the listed references instead of implying simultaneous compliance with every named tube standard.

Alloy and geometry

Choose the actual stainless designation and round, square or rectangular section. Outside dimensions are not supplied, so agree the measured diameter or sides, compatible 2.5 mm wall and customer length before assessing the requested mirror surface.

• Actual alloy and tube route
• Applicable standard and tests
• Outside section and wall
• Customer length and tolerance
• Mirror surface acceptance

Inspection evidence

The surface list contains several finishes without a quantified mirror criterion. Request actual surface and material records; standard references provide no certification, sanitary approval or pressure rating for the delivered tube.
