GENERAL NOTES :
(1) The above table is a reprint of Table 1 of ANSI B36.19.
(2) The decimal thickness listed for the respective pipe sizes represent their nominal wall dimensions. NOTES:
ASchedules 5S and 10S wall thicknesses do not permit threading in accordance with ANSI B1.20.1.
BThese do not conform to ANSI B36.10.

AThese permissible variations in outside diameter apply only to material as finished at the mill before subsequent swaging, expanding, bending, polishing, or other fabricating operations. BOvality is the difference between the maximum and the minimum outside diameter measured at any one cross section. There is no additional tolerance for ovality on matterial having a nominal wall thickness for more than 3% of the outside diameter. On this material, the average of the maximum and the minimum outside diameter measurements will fall within the outside diameter tolerance shown in Table 3. An additional ovality allowance of twice the outside diameter tolerance spreads shown in Table 3, applied ±1/2, is allowed for material having a nominal wall thickness of 3% or less of the nominal outside diameter. CThe wall thickness variation shall not exceed ±12.5% of the nominal wall thickness.

AOvality -The permissible variations in this table apply to individual measurements, incluluding out-of-roundness (ovality) except for the following: For pipe and tube having a nominal wall thickness of 3% or less of the nominal outside diameter, the mean outside diameter shall conform to the permissible variations of this table and individual measurements (including ovality) shall conform to the plus and minus values of the table, with the values increased by 0.5% of the nominal ouside diameter. For pipe and tube over 4 1/2 in. (114 mm) in outside diameter with a nominal wall thickness greater than 3% of the nominal ouside diameter with a nominal wall thickness greater than 3% of the nominal outside diameter, the mean outside diameter shall conform to the permissible variations of this table and individual measurements shall not exceed twice the permissible variations of the table. BEccentricity - The permissible variations in this table to individual measurements including eccentricity.
