The Mechanical Section has introduced the \"Question of the Day\" feature, which not only helps to foster an active atmosphere for technical discussions and guide the direction of such exchanges but also provides users with financial rewards, enabling them to experience various cool features. Regarding the proportion of non-destructive testing for the butt weld joints of pressure vessels, it is generally divided into two categories: 100% for all joints, and at least 20% for some of the joints. For steel cryogenic vessels, the proportion of localized non-destructive testing shall be greater than or equal to (50%). a100% b80% c50% d40% e20% from the fixed volume gauge. Please note: we will close this thread after 24 hours, and at that time we will announce the best response (the best help), as well as the answer and explanation.

The proportion of non-destructive testing for the butt-welded joints of pressure vessels is generally divided into two categories: 100% for all joints, and at least 20% for some of the joints. For steel cryogenic vessels, the proportion of localized non-destructive testing shall be greater than or equal to (50%).
It is generally divided into full (a100%) and locally greater than or equal to (e20%). For low-temperature vessels, the proportion of local non-destructive testing should be greater than or equal to (c50%)
The proportion of non-destructive testing for the butt weld joints of pressure vessels is generally divided into two categories: full testing (a) and partial testing of at least (e). For steel cryogenic vessels, the proportion of local non-destructive testing shall be greater than or equal to (c).
