● Bare pipe or Black / Varnish coating ( customized);
● In loose;
● Both ends with end protectors;
● Plain end , bevel end;
● Marking.
Bending Test— a sufficient length of pipe shall stand being bent cold through 90° around a cylindrical mandrel.
Flattening test-although testing is not required ,pipe shall be capable of meeting the flattening test requirements.
Hydro-static test—except as allowed ,each length of pipe shall be subjected to the hydro-static test without leakage through the pipe wall.
Nondestructive electric test-as an alternative to the hydro-static test ,the full body of each pipe shall be tested with a nondestructive electric test . where nondestructive electric test is performed,the lengths shall be marked with the letters”NDE”
The ultrasonic testing
The eddy current examination
