标准摘要
[中文适用范围]： 本部分 ISO 25902 规定了一种涡流检测方法（以下简称“检测”），用于检测钛无缝管和焊接管（以下简称“管材”）中的缺陷。钛管目前被用作蒸汽动力厂、原子能厂和海水淡化厂的蒸汽表面冷凝器。因此，钛管的质量非常重要，这也是建立涡流检测方法的原因。该方法也适用于钛合金管。在本部分 ISO 25902 中：最小壁厚为 0.3 mm；允许使用矩形槽和钻孔作为参考标准；随着钛管外径的增加，检测到的缺陷也增加。钛管外径的限制为 38.1 mm。 [外文原描述]： ISO 25902-1:2009 specifies a method for the eddy-current examination for detecting flaws in titanium seamless tubes and welded tubes. Titanium tubes are now used as steam surface condensers in steam-power plants, anatomic-power plants and desalination plants. Therefore, the quality of titanium tubes is very important and this is why the eddy-current inspection method was established. This method also applies to titanium alloy tubes.
