A technology for a non-contact (from the Earth surface) magnetic diagnostics of pipelines is developed by Transkor-K Centre (Moscow), which represents an alternative to the standard in-line inspection method (Science in Russia, 6, 2003). Diagnostic inspection device SKIF MBS-04 was demonstrated in the 6th Moscow International Show of the Industrial Property in 2003. Non-contact magnetic technology can be used for inspection of metal pipelines including the pipelines in oil-and-gas complex, in municipal and gas distribution networks, and in compressor plants where the in-line inspection is difficult or impossible. The non-contact magnetic method enables: - to precisely locate (in linear and angular coordinates) metal and insulation coating defects in underground pipeline by inspecting it from the surface of the Earth; - to determine the type of the defect and assess its potential danger; - to carry out monitoring and maintain a database on pipeline current technical condition; - to carry out pipeline system certification. Types of defects to be detected: crack-like defects (laps, rolling skins, guide marks, stress corrosion cracking), weld defects, pipe wall thickness variations (local corrosion pits, groove corrosion), compression marks, corrugations, deviation from the design laying axle.
