Inspection and diagnostics of equipment is performed to determine state of equipment. It is performed either once the period of defectless work is complete or once lifetime of the equipment is over, as well as when defects or failures are found or following failures.The company performs inspection and diagnostics of the following types of tools and equipment:
- expert inspection of lifting cranes, structures and devices
- pipelines with steam and hot water
- steam generators
- gas systems
- equipment installed in fire- and explosion-hazardous and chemical facilities
- vessel diagnostics
- pressurized vessel diagnostics
Nondestructive testing is controlling and assessment of parameters and features of equipment and facilities or separate tools without bringing them out of service (work). The main feature and implicit advantage of nondestructive control compared to other diagnostic method is an opportunity to check parameters and working properties of the unit by applying methods of control which do not require complete stop of the whole system, removing, and sampling. The diagnostics is carries out directly during exploiting the system. Such diagnostics in part decreases material and time costs and increases reliability of the unit being tested.
Thanks to nondestructive testing dangerous and small defects can be found:
manufacturing defects, internal stresses, cracks, micropores, voids, layers, inclusions, etc., including those caused by corrosion processes. We use the following methods of nondestructive testing to control conditions of tools:
- Visual and dimension control; ultrasound hardness and thickness measuring
- Vacuum method: finding through defects (splits, cracks. etc.)
- Magnetic particle method: detecting surface and subsurface defects
- Capillary method: detecting surface and through defects
