The Institute of Metal Physics has developed a UMD-104M computerized system for magnetic nondestructive testing. This system allows detecting and identifying factory and service defects in tubing strings and casing pipes of 48 to 168 mm in diameter with walls up to 10 mm thick. The UMD-104M system is featured with a pneumatic system, which allows testing the tubes with screwed-on couplings.

The UMD-104M magnetic-field flaw detector surpasses installations produced by Tuboscope Vetco Co. (T-V) in that it is equipped with more sensitive matrix sensors, which increases the gap between the sensors and the surface of a pipe from (0.5--1) mm to 5 mm, at the same time, providing a reliable detection of all impermissible defects, regardless of their orientation and location in the pipe wall. The flaw detectors have been successfully used at NGDU Yamashneft, NK Tatneft, Tumen Oil Company, OAO Sinarsky Trubnyi Zavod (Pipe Plant), and SP Tashkent Trubnyi Zavod (Pipe Plant).
