Test Required for ASTM A53 steel pipe

ASTM A53 standard have some basic requirements for seamless and welded steel pipes.

1. Hydrostatic Testing: test pressures for plain and threaded and coupled pipe are specified. Hydrostatic pressure shall be maintained for more than 5 seconds for all sizes of seamless and welded steel pipe. 

2. Mechanical Tests: 

---Tensile Test: Two transverse tests required on the welded steel pipe for NPS 8 and larger, one across the weld and one opposite the weld. 

---Flattening Test: On welded steel pipe 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 

---Number of Tests: Seamless and welded steel pipe – bending, flattening, tensile on one length of pipe from each lot of 500 lengths, or less, of each pipe size.
