| Abstract: | The introduction of TOFD detection technology was mainly focused on. Using 2 000 m3 spherical LPG（ liquefied petroleum gas） tank as an example,the specific technical requirement and standard of TOFD detection technology in periodic inspection of spherical LPG tanks were expounded. The TOFD detection instrument was studied,and then issues in both the instrument adjustment methods and the processing parameters control were discussed. The scanning surface and the bottom face blind area were analyzed and clarified. |
