Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current.
Techinco takes EPC Contracts over in the field of Cathodic Protection Projects. We are specialized in portions of Engineering (E), Procurement (P), Supervision (S), Construction (C), Commissioning (C), and monitoring for the Cathodic Protection System projects.
A corrosion monitoring program provides comprehensive monitoring of all critical components of industrial objects, assets, facilities and plants for signs of corrosion. For reliable operation it is important to identify the location, rate, and underlying causes of corrosion. A corrosion monitoring program identifies any non-conforming alloy components, as these are generally susceptible to accelerated corrosion and can give relatively frequent cause for catastrophic failure. Corrosion Monitoring can provide significant advantages when integrated into both preventative maintenance and the processes inherent to safety management programs.
The surface preparation and application of a protective coatings system is the foundation for a successful long lasting coating system. Many factors should be considered when designing a coating application including but not limited to environment, expected service life and application limitations. The coating process requires inspection at every stage to ensure compliance to the specification. From the preparation of the surface to be coated, through climatic condition monitoring to the dry film thickness evaluation, visual assessment and gauge-based testing will ensure adequate process control.
We also offer Coating inspection of underground pipelines with DCVG/CIPS and PCM/ACVG.
Failure analysis is the process of collecting and analyzing data to determine the cause of a failure. Then we can decide on inspection method and how to use the results FFS and prevent probable future damages.
Fitness for Service
Fitness for service (FFS) assessments are quantitative engineering evaluations that are performed to demonstrate the structural integrity of an in-service component that may contain a flaw or damage, or that may be operating under a specific condition that might cause a failure.
