Today, someone left a message asking us how to detect the weld, what is the weld detection of pipeline products, and how to detect the pipeline weld. Cangzhou Shenlong would like to introduce it to you

How should pipeline welds be tested? Can they be tested in the following two ways?

1. Destructive testing

(1) mechanical properties including tensile test, hardness test, bending test, fatigue test, impact test, etc.;

(2) chemical analysis test including chemical composition analysis, corrosion test, etc.;

(3) metallographic test including macroscopic test, microscopic test, etc.;

2, non-destructive testing

(1) Appearance inspection includes size inspection, geometric shape inspection, appearance scar inspection, etc.;

(2) pressure test including hydrostatic test and air pressure test;

(3) sealing test including airtight test, water test, ammonia test, submerged test, kerosene leakage test, ammonia leak test, etc.;

(4) magnetic powder test;

(5) coloring test;

(6) ultrasonic flaw detection;

(7) radiographic inspection;
