Testing Requirements for seamless and welded API 53 steel pipe
Hydrostatic Testing test pressures for plain and threaded and coupled pipe are specified. Hydrostatic pressure shall be maintained for not less than 5 seconds for all sizes of seamless and ERW pipe.
Tensile Test: Two transverse tests required on the ERW for NPS 8 and larger, one across the weld and one opposite the weld.
Flattening Test: On ERW for NPS 2 and larger, STD and XS wall (not required for XXS pipe)
Bending Test (cold): For NPS 2 and under, XS wall and under; for NPS 1-1/4 and under, XXS wall
Degree of Bend Diameter of Mandrel
For normal A53 users 90 12 x nom. diameter of pipe
For Close Coiling 180 8 x nom. diameter of pipe
Number of Tests: Seamless and Electric Resistance Weld (ERW) – bending, flattening, tensile on one length of pipe from each lot of 500 lengths, or less, of each pipe size.
Permissible Variations for A53 steel pipe
Wall thickness: The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
Weights per foot are plus or minus 10%
Outside diameter: Outside diameter at any point shall not vary from standard specified more than:
NPS Over Under
1-1/2 and smaller +1/64" -1/64"
2 and larger +1% -1%
Lengths of A53 steel pipe
