  • X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as gost 8731 steel pipes hardness value. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of gost 8731 steel pipes hardness value etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
