Scope: Equipment, manufactured completely of metallic materials: pipelines; gas equipment and installations; pressure vessels; low and high pressure boilers; steam turbines; elevating and transport equipment; machinery; constructions and elements for them; cisterns- basic metal, welded joints and their samples, by means of: Visual test methods (VT); Magnetic-particle test methods (MT);Liquid Penetrating Test methods (PT); Radiographic tests (RT); Ultrasonic tests (UT); Walls thickness by means of Ultrasonic thickness measurement (UTМ);
Equipment, manufactured completely of metallic materials: sheets, pipes, pipelines; bars; castings; forgings; pressure vessels and equipment under pressure; low and high pressure boilers; steam turbines; machinery; constructions; cisterns-basic metal, welded joints and their samples, by means of: Destructive tests (DT); Hardness test acc. to: Brinell (HBW); Rockwell (HR), Vickers (HV), Leeb (HL).
Equipment manufactured completely of metallic materials: pipelines, tube smooth bends and heating surfaces (tube coils, heat exchanging tubes) - basic metal, welded joints and their samples: - Presence of the chemical elements chromium (Cr), molybdenum (Mo) and vanadium (V) in steels by means of Spectral analysis.
Equipment, manufactured completely of metallic materials: pipelines; gas equipment and installations; tanks; pressure vessels; low and high pressure boilers; constructions and elements for them; cisterns-base metal, welded joints and their samples: - Hermeticity/ tightness (presence/absence of leakage) by means of Leak testing (LT) (gas-hydraulic methods) using foaming compounds.
Coatings on ferromagnetic and non-ferromagnetic bases: Thickness measurement by means of Eddy-current testing (ECT) and Magnetic induction testing methods. Electrical insulation coating of metals: Density of insulation coating by means of Electro-sparkling testing methods.
Rope-way lines for transportation of passengers: Presence, type, size and location of discontinuities/ imperfections in ropes by means of Magnetic Rope Testing (MRT). Pipelines, tube bends and heating surfaces (tube coils, heat exchanging tubes): Departure from circularity (Ovality).
Welded joints manufactured of metallic materials: Types, sizes and distribution of the imperfections contained in the weld volume by means of Destructive tests (DT).
