OD Tolerance: +/- 1%
Wall Tolerance: +/- 12.5%
Mass: +10% -5%

ASTM A139 Welded Pipes Weight

The weight of any length of pipe shall not vary more than 10% over the specified weight.

The weight of any length of pipe shall not vary more than 5% under the specified weight when the specified wall thickness is 0.188″ or less or more than 5.5% under when the wall thickness is greater than 0.188″.

ASTM A139 Welded Pipes Thickness

The minimum wall thickness at any point shall be not more than 12.5% under the nominal wall thickness.

ASTM A139 Welded Pipes Circumference

The pipe shall be substantially round. The outside circumference of the pipe shall not vary more than 1.0%, but not exceeding ¾ in. from the nominal outside circumference based upon the diameter specified, except that the circumference at ends shall be sized, if necessary, to meet the requirements of Section 15.

ASTM A139 Welded Pipes Straightness

Finished pipe shall be commercially straight. When specific straightness requirements are desired, the order should so state and be agreed upon between the purchaser and the manufacturer.

A hydrostatic test with a stress no less than 60% of the minimum yield at room temperature shall be performed on each piece by the manufacturer.
