Below there are some examples of works and laboratory testing at the hazardous production facilities.

Ultrasonic testing (UT) method is presently one of the main methods of non-destructive testing of welded joints on technical devices, forgings, sheet steel and other products, offered in 1928 by a Soviet physicist S.Y. Sokolov.

Ultrasonic defectoscopy of longitudinal and circular welds on the vessel Е-40 at VDU-1, Ryazan Oil Refinery Company JSC, 2015.

Eddy current testing (ECT) - enables search for defects and assessment of the tested items’ properties, and has a wide industrial application both during manufacturing and operation of equipment.

Eddy current testing. “Tube-tubesheet” welded joints of air cooler sections are subject to technical diagnostics.Weld scanning was made at the weld middle and along its boundaries, including inside the tube.

Eddy current testing. Overhead process pipelines of the workshop No.2 GFU unit at Ryazan Oil Refinery Company JSC are subject to technical diagnostics. Dashed line shows a trajectory of transducer movement at reducers.

Visual and dimension inspection (VI&DI) is referred to the most informative methods of non-destructive testing, is basic and precedes all other methods.

Internal examination and visual and dimension inspection of the vessel Е-40 at VDU-1, Ryazan Oil Refinery Company JSC, 2015. Swollen areas are detected on the internal and external surface of Е-40 vessel shell course (discontinuities, bulges, lamination).

Vibration diagnostics and monitoring (VD)

External examination of rotating equipment is performed, components, supports and foundation are examined, vibrodiagnostic measurements are made according to the examination program, and the requirements of standards and normative and technical documentation.

Vibration diagnostics and monitoring. Nitrogen compressor plant by KWANGSHIN MACHINE INDUSTRY CO.LTD is subject to technical diagnostics, Sibur-Neftekhim JSC ethylene oxide and glycols production, Dzerzhinsk, the Nizhny Novgorod region.

Thermal testing (TT)

Thermal testing of overhead process pipelines at the GFU unit of Ryazan Oil Refinery Company JSC was performed in accordance with the requirements of RD-13-04-2006 Methodical recommendations on the procedure of thermal inspection of technical devices and structures applied and operated at hazardous production facilities, GOST R 54852-2011 Buildings and structures. Thermal testing method for the enclosing structures thermal insulation quality control.

Analysis of corrosion and erosion wear and tear of technical devices

Technical documentation is reviewed together with the results of on-site investigation of the technical device, corrosion and erosion wear and tear rates are determined within individual apparatuses and vessels of the units. Based on the review results, potentially hazardous components and areas are identified.
