DIN 17172 STE480.7 seamless steel pipe has a hollow section, a large number of fluid pipeline, such as the transportation of oil, natural gas, gas, water and some solid materials pipeline. We will introduce in detail the DIN 17172 STE480.7 seamless steel pipe surface quality inspection method:
1. UT ultrasonic inspection: it is sensitive to the surface and internal crack defects of all kinds of materials with uniform material.
2. Eddy current testing ET: mainly sensitive to point defects, standard: GB/T7735-2004 grade: B grade.
3. Magnetic particle MT and magnetic leakage inspection: magnetic inspection, suitable for the detection of surface and near surface defects of ferromagnetic materials.
4. Electromagnetic ultrasonic inspection: no coupling medium is needed, can be applied to high temperature, high speed, rough DIN 17172 STE480.7 seamless steel pipe surface inspection.
5. Permeable flaw detection: fluorescence, coloring, detection of seamless steel tube surface defects.
