钢管的无损检测.第5部分:无缝与焊接铁磁钢管表面缺陷检测用磁粉探伤

[中文适用范围]： ISO 10893的本部分规定了无缝和焊接铁磁钢管的磁粉检验要求，用于检测管体和端部端面/斜面的表面缺陷。 对于管体，规定了管材全部或部分外表面表面缺陷的检测要求。 然而，根据买方和制造商之间的协议，它可以适用于从管端部开始的有限长度内表面，具体取决于管直径。 此外，ISO 10893的这一部分可酌情用于在修整管子表面之前定位由另一种无损检测方法（例如超声波）检测到的外表面缺陷的位置，并确保完全去除缺陷。 穿衣完成后的瑕疵。 对于平端管和斜端管端部的端面/斜面，ISO 10893 的本部分规定了层状缺陷的检测要求，这些缺陷可能会干扰后续的制造和检查操作（例如焊缝的焊接和超声波检查） ）。 ISO 10893 的这一部分适用于检测端面/斜面的缺陷（层状缺陷除外）。 在这种情况下，沿基本上垂直于被检测的特定缺陷的方向的方向施加磁化。 也可适用于空心型材的检测。 [外文原描述]： ISO 10893-5:2011 specifies requirements for magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections on the tube body and the end/bevel face at the ends. For the tube body, it specifies requirements for the detection of surface imperfections on all or part of the outside surface of tubes. However, by agreement between the purchaser and manufacturer, it can be applicable to the inside surface over a limited length from the ends of tubes, dependent on the tube diameter. In addition, ISO 10893-5:2011 can be used, as appropriate, to locate the position of external surface imperfections detected by another non-destructive testing method (e.g. ultrasonic) prior to dressing of the tube surface, 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, ISO 10893-5:2010 specifies requirements for the detection of laminar imperfections which can interfere with subsequent fabrication and inspection operations (e.g. welding and ultrasonic inspection of the welds). ISO 10893-5:2011 is applicable to the detection of imperfections, other than laminar imperfections, on the end/bevel face. In this case, magnetization is applied in the direction essentially perpendicular to the orientation of the particular imperfections being detected. It can also be applicable to the testing of hollow sections.
