Mechanical Steel Pipes And Tubes

Diameter, Wall,A and Ovality Toerances

(All Conditions Except Tubing with Bead Removed)

NOTE 1 - Ovality is the difference between maximum and minimum outside diameters measured at any one cross section. There is no additional tolerance for ovality on tubes having a nominal wall thickness of more than 3% of the outside diameter. NOTE 2 - For sizes up to and including 5-in. (127.0-mm) outside diameter, an ovality tolerance of twice the tabular outside diameter tolerance spread shown is applied diamter readings should fall within the outside diameter tolerances as shown in this table. NOTE 3 - For sizes over 5-in. (127.0mm) to and including 16-in. (406.4-mm) outside diameter, when the specified wall thickness is 3% or less of the outside diameter, the ovality shall not exceed 1.5% of the specified outside diameter.

TABLE 3 Diameter, Wall,A and Ovality Tolerances for Tubing with Bead Removed

NOTE 1 - Ovality is the difference between maximum and minimum outside diameters measured at any one cross section. There is no addifional tolerance for ovality on Mechanical Steel Pipes And Tubes having a nominal wall thickness of more than 3% of the outside diameter. NOTE 2 - An ovality allowance of twice the outside diameter tolerance, shown in this table, is applied one half plus and one haif minus to the outside diameter, for tubes having a nominal wall thickness of 3% or less of the outside diameter. The average of the maximum and minimum outside diameter readings should fall within the outside diameter tolerances of this table. NOTE 3 - Mechanical Steel Pipes And Tubes may be specified to only two of the three following dimensions-outside diameter, inside diameter, or wall.
