Features of pipeline NDT

The characteristic of non-destructive testing is that it can be tested without damaging the material and structure of the test piece. Therefore, after implementing non-destructive testing, the inspection rate of the product can reach 100%. However, not all items and indicators that need to be tested can be NDT, and NDT technology has its own limitations.

Correctly choose the timing of implementing non-destructive testing: when non-destructive testing, according to the purpose of non-destructive testing, the timing of non-destructive testing must be selected correctly.

Correct selection of the most appropriate non-destructive testing method: Since various testing methods have certain characteristics, in order to improve the reliability of the testing results, the types of defects that may be generated are expected according to the material of the equipment, manufacturing method, working medium, use conditions and failure mode , shape, location and orientation, select the appropriate non-destructive testing method.

Comprehensive application of various non-destructive testing methods: any non-destructive testing method is not perfect, each method has its own advantages and disadvantages. Several testing methods should be used as much as possible to complement each other to ensure the safe operation of pressure-bearing equipment.
