Tolerance of Stainless Steel Tubes and Pipes

Deviation

In the production process, because the actual size is difficult to meet the nominal pipe size requirement, that is, it is often larger or smaller than the nominal size, so the standard stipulates that there is a difference between the actual size and the nominal size of the stainless steel pipe. A positive difference is called a positive deviation, and a negative difference is called a negative deviation.

Tolerance

The standard stipulates that the sum of the absolute value of the positive and negative deviations of stainless steel pipes is called tolerance, also called “tolerance zone”.

For wall thickness we have two choices, Minimum Wall Thickness and Average Wall Thickness. Difference Standard Specifications have different tolerance requests. Mainly specify in ASTM A999 or ASTM A1016 or EN 10216-5
