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.

Here is a general guideline for thickness tolerance of pipes. Mill under-tolerance of pipe thickness should be complied with the followings unless otherwise specified in the material standards. - Pipe identified as only seamless or pipe indentified as duel grade, such as seamless or welded: 12.5% - Pipe identified as only welded: 0.3 mm (0.01 inch) Hope this Hot Rolled Seamless (HRS) Steel Tubing - Hot Finished tolerances thickness of seamless materialHot rolled seamless (HRS) tube (also known as HFS or Hot finished seamless) is a lower-cost product than CDS tube and is a good material for applications that do not require the close dimensional tolerances and quality of surface finish that CDS tube provides. If tight tolerances are required, machining is used to finish the product to exact specifications.

Produced from hot rolled 1026, the cold drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.ASTM A519 Hot Finished Seamless - Chicago Tube & IronDiameter tolerances are not applicable to normalized and tempered or quenched and tempered conditions. The common range sizes of hot finished tubes is 1-1/2 inch (38.1 mm) to 10-1/4 inch (273.0 mm) outside diameter with wall thickness at least 3 percent or more of outside diameter, but not less than 0.095 inch (2.41 mm).
For seamless tubes with inside diameter less than 1/2 inch (or less than 5/8 inch when the wall thickness is more than 20 percent of the outside diameter), which cannot be successfully drawn over a mandrel, the wall thickness may vary 15 percent over or under that specified, and the inside diameter will be governed by the outside diameter and wall thickness variations.ASTM A312 Size Tolerance - Permanent SteelSize tolerance table of astm a312: Standard: Out diameter (mm) Wall thickness (mm) Length (mm) ASTM A312 48.26 +0.40 -0.80 +(Unspecified)-12.50%.
