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。这些测试方法的目的是暴露管道材料或焊接区域中的缺陷，例如不连续性、接缝、裂纹、孔洞、空隙和管道特定结构特征的其他缺陷。当生产者和购买者之间达成协议时，使用无损检测代替破坏性静水压检测。 在编写本文件时没有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.
