Dimensional Tolerance

ASTM A688 U bend tube tolerance of outside should be accordance with specification A1016/M, bent portion of U tubes for R =2 X D or greater, tolerance shall deviate from the nominal diameter prior to bending by more than 10 %, if less than 2 X D is speciﬁed, tolerances could be greater, minimum wall thickness shall not exceed +20 % − 0, average wall thickness are 10 % of the nominal wall thickness, bent area wall tolerance shall not be less than value determined by the equation: 4RT/(4R+D).
