Radiographic testing is one of the most informative and reliable DNT methods. This method is overall used for diagnostic such facilities as pipelines of various diameters, metal constructions, technological equipment, products made from composites and so on.
Visual and measurement testing is performed to obtain initial information about the object under inspection (VMT). VMT is directed at testing of blank parts quality for melding and also evaluation of welded joints quality. External expertise is an integral part of technical diagnostics. It is performed not depending on using other DNT methods.

Basic by realization of thermal imaging testing is creation of apparatus facilities, providing transformation of the temperature distributing or infrared to the visible image. Realization of possibilities of thermal imaging testing, providing both the exposure of internal defects in different objects and effective decision of problem of «nightly vision», findings out the hidden or disguised objects or realization of searching measures are in difficult weather terms, stipulated creation of wide spectrum of thermal-imaging of apparatus facilities: portable, mobile, stationary.
Magnetic coating thickness gauge MT-2007 is designed to measure thickness of paint and lacquer, electroplating, fire-retardant, and any other non-magnetic current conducting and non-conducting coatings on ferromagnetic (steel, cast iron etc.) foundations.
Magnetic particle testing (MPT) is high on the list in the system of non-destructive testing methods. This is due to its high-speed response to surface and subsurface defects, simplicity, flexibility and clear presentation of testing results.
The vacuum-bubble testing method allows to detect penetraion defects. When testing by this method, a vacuum chamber is installed on the side of the test section of the welded joint moistened with indicator solution, and negative pressure is generated in a chamber. Due to the generated differential pressure, atmospheric air penetrates through-and-through defects, causing their bubble indication.
Spark testing method is a method of electrical non-destructive testing based on recording electricalbreakdowns and (or) changes in the parameters of the test item in the environment or at the section.
