CHEMICAL REQUIREMENTS FOR A53

 

Seamless and ERW C max % Mn max % P max % S max %
Grade A 0.25 0.95 0.05 0.045
Grade B 0.30 1.20 0.05 0.045
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.
Mechanical Tests:
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.
