REQUALIFICATION

1. TEST METHOD

Each cylinder or tube shall be visually inspected externally and be subjected to an acoustic emission test and, when required, to a follow-up ultrasonic or radiographic examination.

APPENDIX A

REQUALIFICATION

2. VISUAL EXAMINATION

Each cylinder or tube shall be visually inspected externally, in accordance with CGA C-6-2007.

3. ACOUSTIC EMISSION TEST

3.1 Scope of test

The entire vessel under test shall be monitored using at least two transducers mounted at its extremities. The transducers shall be at the same angular location and approximately 25 mm from the tangent point at the vessel shoulder.

3.2 Transducers

The transducers shall be of anticoincident piezoelectric construction and resonant in the range of 75 to 400 kHz and with a sensitivity of at least -65 dB referred to as 1V/microbar.

3.3 Transducer coupling

Sensors shall be coupled to the vessel using a viscous or solid couplant and held in place by suitable holders.

3.4 Calibration

The system shall be calibrated using an acoustic emission simulator consisting of breaking a pencil lead on the surface of the vessel or of an ultrasonic pulse whose intensity at one metre from the pulser is equal to that of the pencil lead break. The system gain and threshold shall be set at values that certificate detection and location of the simulated emission over the surface of the vessel and that minimize background noise. The precision and accuracy of the location function shall be recorded at the centre of the vessel between the transducers.

APPENDIX A

REQUALIFICATION

3.5 Pressurization

Hydrostatic pressure shall be applied monotonically from zero to test pressure as defined by CAN/CSA B339-02, at a rate not exceeding 1.4 MPa per minute. A method shall be provided to continuously read the pressure. Acoustic emission data shall be recorded during and after pressurization.

3.6 Interpretation of Results and Follow-up Examination

The vessel shall be subjected to follow-up ultrasonic and visual examination when the rate of emission exceeds two events per 0.7 MPa, regardless of

signal amplitude, at any one point on the vessel and when the flaw is deemed active according to ASTM E569-07, or activity is confirmed using the Kaiser effect. To apply the Kaiser effect, the test is interrupted, the pressure is reduced by at least 25%, and the vessel is repressurized to the maximum pressure previously attained; if emission is absent during depressurization and repressurization and reappears when the previous maximum pressure is exceeded, it shall be considered active. Inspection shall be carried out by personnel qualified to Level II of CAN/CGSB-48.9712-2006 or the equivalent, to determine the flaw size. Such examination shall be carried out over the complete circumference of the vessel over a distance of at least one vessel diameter in each direction from the sources of emission.

If this threshold is exceeded at a pressure less than the service pressure, the vessel shall be withdrawn and searched in the emitting zones for flaws of the "oxidation" type.

If this threshold is exceeded at a pressure equal to or greater than the service pressure, the vessel shall be withdrawn and searched in the emitting zones (indicated by the location system) for flaws of the "cracking" type.

Vessels shall be rejected where the depth of the penetration of the flaw through

the vessel wall reduces wall thickness to a value less than the values specified in CGA C-6-2007. Defects with a depth in excess of 15 percent of wall thickness and a sharp bottom shall not be tolerated. Vessels with such crack-like defects shall be removed from service or conditioned by removal of the defect and verification of vessel strength by wall thickness measurement and
