The b7 qt steel round bars must go through strict inspection before putting into use. Inspection of plate groove of b7 qt steel round bars, vertical oil tank: After finishing the groove processing of oil tank plate, it is necessary to conduct dye penetrant inspection on the groove. This process is mainly aimed at the hard damage of groove in the machining process and the defects of the plate itself. If any defect is found, it shall be processed again until the defect disappears.
