Tolerances are also provided for stainless pipe on straightness (1/8 in 10) and for cut lengths (-0, +1/4). Notice that there is no requirement or tolerance for the ID. The tolerances for most nickel alloy welded pipe are identical or very similar to those for stainless.See all results for this question

During the rolling process the rollers bow slightly, which results in the sheets being thinner on the edges.Seamless or welded pipes? - BUTTINGThe wall thickness tolerance of 12.5 % for hot rolled seamless pipes is specified fundamentally in ASTM A999 or EN ISO 1127 T2. However, wall thickness differences caused by the manufacturing procedure may lead to a possible eccentricity, that is, to a deviation from symmetry (Diagram 2).Seamless Steel Pipe Wall Thickness ToleranceThe outer diameter of hot-rolled seamless pipe is generally greater than 32mm, the wall thickness is 2.5-200mm, the outer diameter of cold-rolled seamless steel pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm, cold rolling has higher dimensional accuracy than hot rolling.
