Comparison of destructive and non-destructive test for steel pipe

There are destructive and non-destructive test during the steel pipe production. However, what’s the difference for them when they applied in seamless steel pipe, ERW steel pipe and galvanized steel pipe?

1. Literal meaning for destructive and nondestructive testing. Nondestructive testing doesn’t affect the detection performance of the test object like steel pipe;

2. For synthesis aspect, if the test for steel pipe is non-destructive, the steel pipe can detect 100% of the comprehensive test. Of course, the destructive test is impossible for steel pipe in order to keep the high quality.

3. If there is destructive test for steel pipe, generally speaking, this kind of test would apply for raw materials, such as the commonly used tension, mechanical compression, bending, nondestructive testing of raw materials manufacturing. Therefore, it is not only used to manufacture the raw material for each intermediate step, the entire finished product of the test, but also the service on the test equipment.
