Abstract

The results of in-tube magnetic nondestructive testing performed on a six-branch corridor of gas main pipelines are given. The comparative analysis of the results of three inspections conducted for the period of 2000–2009 is performed. The high efficiency of in-tube nondestructive testing with the use of modern domestic magnetic pig flaw detectors is shown.
