What is the non-destructive testing of seamless cs pipe?

Nondestructive Testing, referred to as NDT, is a modern inspection technology that detects the shape, location, size and development trend of internal or external defects on the premise of not damaging the inspected object. In recent years, it has been widely used in steel pipe production. in. The non-destructive testing methods used in the production of seamless cs pipe include ultrasonic testing, magnetic particle abrasion, eddy current testing, penetrant testing, radiographic testing, magnetic flux leakage testing, etc. Various testing methods have a certain range of application.

Non-destructive testing requirements for seamless cs pipe:

The seamless steel pipe should be straight, the bending filling is less than 2mm/m, and the full length of the steel pipe should be less than 15mm, the pipe end should be flat, and the burr should be less than 0.5mm. There is no serious bulge on the outer surface, and the height of the bulge is less than 0.5mm.

Non-destructive testing is a faster detection method. All kinds of seamless cs pipe can be used. It can detect various defects of the pipe in a short time, which brings great convenience to the production of steel pipes.
