Confirm a consistent pipe specification before ordering the requested stainless seamless tube.

Alloy and outside diameter

The detail lists several stainless grades and an outside diameter entry of 50 without clear units. Agree one actual alloy and the requested 21.3 mm outside diameter, resolving the separate diameter reference before supply.

Wall and finish

The actual wall option is 2.5 mm, with several length choices. BA and NO.1 surface descriptions both appear, so select the delivered finish and confirm the cold rolled or other actual production route.

• Actual stainless alloy
• Outside diameter and tolerance
• Compatible wall and length
• Selected surface and route
• Brand and inspection evidence

Procurement evidence

TGCC and ASTM appear as title references. Request actual brand provenance and the applicable pipe standard with inspection records; neither wording establishes manufacturer identity, pressure capability or certified compliance for a particular pipe.
