43、ested for the verification of hydraulic leaktightness by either the eddy current method or the flux leakage method, using one of the following automated or semi-automated techniques: a) concentric coil technique (eddy current method) (see Figure 1); b) segment coil technique (eddy current method) (s
44、ee Figure 2); c) fixed or rotating probe/pancake coil technique (eddy current method) (see Figure 3); d) fixed or rotating magnetic transducer technique (flux leakage method) (see Figure 4); e) multiple concentric magnetic transducers technique (flux leakage method) (see Figure 5). For all technique
45、s, the chosen relative speed of movement during the testing shall not vary by more than g11410 %. NOTE 1 It is recognized that there can be, as in the case of hydraulic testing under normal production conditions, a short length at both tube ends which cannot be tested. NOTE 2 See Annexes A and B for
46、 guidelines on the limitations of the eddy current test method and flux leakage test method. 5.1.2 When testing seamless or welded tubes using the eddy current concentric coil technique, the maximum tube outside diameter tested shall be restricted to 250 mm. Square or rectangular tubes with a maximu
47、m dimension across the diagonal of 250 mm may also be tested using this technique with adequately shaped coils. 5.1.3 When testing tubes using the segment coils technique, the maximum tube outside diameter that shall be tested shall be limited to: g127 g135 219,1 mm for 2 g117 180 coils; g127 g135 5
48、08,0 mm for 4 g117 100 coils. 5.1.4 When testing seamless or welded tubes using the fixed or rotating probe/pancake coil eddy current technique or the fixed or rotating magnetic transducer flux leakage technique, the tube and the probes/pancake coils/magnetic transducer shall be moved relative to each other or the movement shall be simulated by electronic commutation through the individual probes composing the pancake, such that the whole of the tube surface is scanned with cov
