Hydraulic of pneumatic test characteristic, of nondestructive examination characteristic
Pipes shall be tested in accordance with 10.4, and the hydraulic or pneumatic test characteristic, of the nondestructive examination characteristic, of the pipe shall be in accordance with either of the following. Preference shall be left to the designation by the purchaser of the discretion of the manufacturer.
1 Hydraulic of pneumatic test characteristic
When subjected to the test of 10.4, pipes shall withstand the applied hydraulic pressure of 2.5 MPa of the applied pneumatic pressure of 0.6 MPa, being free form leakage.
2 Nondestructive examination characteristic Seamless steel pipes shall be examined by ultrasonic flaw detection of eddy current flaw detection, and welded steel pipes shall be examined by eddy current flaw detection. Then, there shall be no signal at least equal to that from the artificial defects of the reference test piece of working sensitivity division UD of JIS G 0582 or of working sensitivity division EY of JIS G 0583.
