DIMENSIONS AND WEIGHT TOLERANCES

ROUND TUBING AND PIPEASTM A53

Weight - The weight of the pipe as specified in Table X2 and Table X3 (ASTM SpecificationA53) shall not vary by more than #10 percent.Note that the weight tolerance of #10 percent is determined from the weights of thecustomary lifts of pipe as produced for shipment by the mill, divided by the numberof feet of pipe in the lift. One pipe sizes over 4 in. where individual lengths may beweighed, the weight tolerance is applicable to the individual length.Diameter - For pipe 2 in. and over in nominal diameter, the outside diameter shallnot vary more than #1 perecent from the standard specified.Thickness - The minimum wall thickness at any point shall be not more than 12.5percent under the nominal wall thickness specified.

SQUARE AND RECTANGULAR TUBING

Outside Dimensions - The specified dimensions, measured across the flats atpositions at least 2 in. from either end of square or rectangular tubing and includingan allowance for convexity or concavity, shall not exceed the plus and minus toleranceshown in the following table:

The respective outside dimension tolerances include the allowances for convexityand concavity.

STANDARD MILL PRACTICE—ContinuedSteel Pipe and Tubing

Lengths - Structural tubing is commonly produced in random lengths, in multiplelengths, and in definite cut lengths. When cut lengths are specified for structuraltubing, the length tolerances shall be in accordance with the following table:

Straightness - The permissible variation for straightness of structural tubing shallbe 1/8 in. times the number of feet of total length divided by 5.Squareness of Sides - For square or rectangular structural tubing, adjacent sidesmay deviate from 90 deg. by a tolerance of plus or minus 2 deg. max.Radius of Corners - For square or rectangular structural tubing, the radius of anyoutside corner of the section shall not exceed three times the specified wall thickness.Twist - The tolerances for twist or variation with respect to axial alignment of the section,for square and rectangular structural tubing, shall be as shown in the following table:

Twist is measured by holding down one end of a square or rectangular tube on aflat surface plate with the bottom side of the tube parallel to the surface plate andnoting the height that either corner, at the opposite end of the bottom side of thetube, extends above the surface plate.Wall Thickness (A500 only) - The tolerance for wall thickness exclusive of the weldarea shall be plus and minus 10 percent of the nominal wall thickness specified. Thewall thickness is to be measured at the center of the flat.
