TOFD detection of stainless steel composite plate spherical tank based on cladding side

In view of various defects in the manufacturing and use of stainless steel composite plate spherical tank, TOFD detection technology based on the cladding side is adopted, and the TOFD detection technology is simulated by CIVA software, and the reliability of the process is verified by the comparison with the test block. Finally, a 500 m³ stainless steel composite plate spherical tank is tested on site by this detection technology. The results show that the detection technology based on the cladding side can effectively reduce the blind area coverage of TOFD detection of stainless steel clad plate, and has a high signal-to-noise ratio, which has a certain guiding significance for the development of TOFD detection of the cladding side of stainless steel clad plate spherical tank in the cladding side.
