適用范圍：This part of ISO 10893 specifies requirements for magnetic particle inspection of seamless and weldedferromagnetic steel tubes for the detection of surface imperfections on the tube body and the end/bevel faceat the ends.For the tube body, it specifies requirements for the detection of surface imperfections on all or part of theoutside surface of tubes. However, by agreement between the purchaser and manufacturer, it can beapplicable to the inside surface over a limited length from the ends of tubes, dependent on the tube diameter.In addition, this part of ISO 10893 can be used, as appropriate, to locate the position of external surfaceimperfections detected by another non-destructive testing method (e.g. ultrasonic) prior to dressing of the tubesurface, and to ensure complete removal of the imperfection after dressing is complete.For the end/bevel face at the ends of plain-end and beveled-end tubes, this part of ISO 10893 specifiesrequirements for the detection of laminar imperfections which can interfere with subsequent fabrication andinspection operations (e.g. welding and ultrasonic inspection of the welds).This part of ISO 10893 is applicable to the detection of imperfections, other than laminar imperfections, on theend/bevel face. In this case, magnetization is applied in the direction essentially perpendicular to theorientation of the particular imperfections being detected.It can also be applicable to the testing of hollow sections.
