Positive tolerance on Pipe wall thickness
Positive tolerance on Pipe wall thickness
(OP)
Please can somebody tell me about positive tolerance on pipe wall thickness (ASTM A106 Gr. B). As per my interpretation, ASTM A106 mentions only about negative tolerance i.e minus 12.5%.
Example: Pipe thickness for a schedule 80 3'' pipe (carbon steel) is 7.62mm whereas received pipe with wall thickness 8.5mm (i.e approximately 112.5% WT).
Please advise me if I'm wrong.
