Material & Corrosion
Our Services Include:
Corrosion Assessment and Risk Analysis
- Corrosion risk assessments (CRA) for pipelines, pressure vessels, tanks, etc.
- Material degradation mechanisms identification (e.g., CO₂ corrosion, H₂S corrosion, MIC, erosion-corrosion)
- Root cause analysis (RCA) of corrosion failures
- Remaining life assessments and fitness-for-service (FFS) evaluations
- Criticality ranking of corrosion-prone areas
Materials Selection and Compatibility
- Selection of suitable materials based on:
- Fluid composition (sour vs sweet)
- Pressure/temperature conditions
- Service environment (subsea, onshore, desert, arctic, etc.)
- Advice on Corrosion-Resistant alloys (CRAs) vs carbon steel + corrosion allowance
- Compatibility studies for chemical injection systems, linings, and coatings
Corrosion Control Strategies
- Cathodic protection (CP) system design and validation (impressed current or sacrificial anodes)
- Chemical inhibition programs (e.g., corrosion inhibitors, biocides, scale inhibitors)
- Coating systems (specification, application methods, inspection requirements)
- Internal lining recommendations for tanks and pipelines
Design for avoiding Dead Legs, avoidance of crevice corrosion and stagnant areas
Corrosion Monitoring & Inspection Planning
- Specification of corrosion monitoring tools:
- Corrosion coupons
- Electrical resistance (ER) probes
- Linear polarization resistance (LPR) probes
- Online monitoring systems
- Inspection plans using:
- Ultrasonic testing (UT)
- Magnetic flux leakage (MFL)
- Radiography (RT)
- Corrosion under insulation (CUI) techniques
- Baseline surveys and periodic reassessment strategies
