Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:
Dimensions
Weights
Straightness
Lengths
Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.
Size and surface inspection
NDT and pressure test and third party certication
Hydrostatic
Drifting test
Physical and chemicail analysis
Hardness and pressure test.
Electromagnetic
Magnetic particle
