The third party inspection of 3454 Carbon ERW Steel Pipe

Tolerance of outside diameter and wall thickness:

Tolerance of OD and W.T

Division	Tolerance on O.D		Tolerance on W.T
Cold finished ERW Steel Pipe	24A or under	+/-0.3mm	Under 3mm 3mm or over	+/-0.3mm +/-10%
	32A or over	+/-0.8%
For pipes of nominal size 350A or over,the tolerance on O.D maybe determined by the circumferential length. In this case,the tolerance shall be +/-0.5%
