本信息报告描述了钢管的涡流检测、漏磁检测、超声波检测和磁粉检测。这些试验方法的目的是暴露管道材料或焊接区中的缺陷，例如不连续、接缝、裂纹、孔洞、空隙和管道特定结构的其他缺陷。如果生产商和采购商达成一致，则使用无损检测代替破坏性静水压验证试验。 本文件编制期间未考虑飞机和航空航天应用。

This Information Report describes eddy current testing, flux leakage testing, ultrasonic testing, and magnetic particle testing of steel tubing. The purpose of these testing methods is to expose flaws in the tube material or weld zone, such as discontinuities, seams, cracks, holes, voids, and other imperfections characteristic to the specific construction of the tubing. When agreed upon between the producer and purchaser, nondestructive testing is used in lieu of destructive hydrostatic pressure proof testing. Aircraft and Aerospace applications were not considered during the preparation of this document.
