Existing pipelines and Process Facilities CP system detailed overall electrometric study includes:
- CP means condition survey
- CP facility optimum operation mode determination
- Adjacent lines and multiple pipelines CP means harmful influence presence test
- Pipeline protection along entire length test (by remote electrode method)
- Pipeline protection in time test
- Corrosiveness of soils (in regard to steel) determination test
- Insulation coating condition control (determination of damage and defects object snapping in layouts and/or terrains)
- Determination of pipeline locations exposed to instrument control in pits
- Determination of pipeline corrosion condition in pits (selectively)
- Soil study for possible microbiological corrosion locations identification
- Sampling of soils in boreholes
- Determination of bacteria microbiological activity in sampled
soils - Issuance of recommendations on insulation coating and pipe repair, CP facilities optimum operation mode determination, microbiological corrosion elimination
- Pipeline corrosion map compilation and corrosion condition forecast
Execution of similar works in stray current areas.
