TYPES OF CORROSION IN OIL & GAS INDUSTRIES & PETROCHEMICAL PLANTS
Each type of corrosion is studied together with possible prevention for pressurized vessel and piping already in service, or during a new plant design.
Specific corrosion occurring in industrial installations:
Hydrogen Induced Cracking, High Temperature Hydrogen attack, high temperature sulfur corrosion, oxidation, flue gas corrosion, naphthenic acid corrosion, polythionic acid corrosion, caustic soda stress cracking, Amines corrosion, CO2 corrosion
Specific corrosion existing in chemical industry: corrosion by mineral acids, bases, nitrates, ammonia or chlorine.
Many corrosion case studies observed in process industry units: identification of corrosion root cause and mitigation to apply.

CORROSION PREVENTION & INSPECTION
Material selection and detailed engineering design to avoid corrosion.
Identification of operating windows.
Corrosion control by means of sampling, use of corrosion coupons and probes.
Cathodic protection with sacrificial anodes or imposed current.
