ASTM A213 wall-thickness

ASTM A213 wall-thickness

(OP)
So here's probably a dumb question. ASTM A213 covers "minimum-wall-thickness, seamless ferritic and austenitic steel .." tubing.
Does A213 requires no nor mentions anything on a mill undertolerance on the tubing wall thickness, like A269 or A249 does?
As far as I know it doesn't (given the bold quote), yet the spec doesnt state anything else on wall thickness (tolerance), which kinda left me clueless.

RE: ASTM A213 wall-thickness

You need to look at referenced or ASTM material specifications listed within ASTM A 213. For your case, it would be ASTM A 1016, originally A 450 - General Requirements for Ferritic Alloy Steel, Austenitic Alloy Steel and Stainless Steel Tubes.

RE: ASTM A213 wall-thickness

I only have A213-04 and A1016-04, from what I can see (table 2) there's no mill undertolerance, only overtolerance.

RE: ASTM A213 wall-thickness

Correct. Tubing is ordered to either average or minimum thickness. There is no undertolerance for minimum wall thickness.

RE: ASTM A213 wall-thickness

Unless specified as average wall tubing ordered to this spec is presumed to be min wall and therefore has no underside tolerance.
