Operations of control are executed continuously during all the
construction process:
- Incoming inspection of supplied materials and equipment;
- Operational control during the construction process;
- Non-destructive control of welded joints;
- Ground, insulation and laying control.
Both basic (pipes of large diameter, electrodes, welding wire,
insulation materials) and additional materials (constructions
for buildings and edifices) are subjected to the incoming
inspection. Under the operational control we mean a continuous
process of control, that is carried out coincidentally with
every operation of building and construction works complex.
