Inspection & Corrosion Engineering
Course Code: EM34
►Course Objective
- study steels and alloys degradation and corrosion,
- explain the operating parameters and fluid characteristics responsible of main corrosion phenomenon,
- identify field inspection recommendations on pressure equipment and piping to prevent corrosion failures.
►Target Audience
- Experienced engineers,
- managers
- technical staff involved in safe operation and integrity of pressure equipment installed in refineries,
- chemical
- petrochemical plants.
►Course Outline
METALLURGY USED FOR PRESSURE EQUIPMENT & PIPING MANUFACTURING
- Ferrous and non-ferrous material: microstructure, composition, mechanical properties.
- Plates, forging, castings, piping, rolling, welding, post weld heat treatment.
- Pressurized vessel manufacturing.
USUAL TYPES OF CORROSION & DETERIORATIONS
- Different types of industrial corrosion: uniform, pitting, crevice, intergranular, stress corrosion cracking, corrosion-erosion, galvanic, selective.
- Definitions and basic mechanism: wet corrosion, dry corrosion.
- Metallurgical deterioration: brittle fracture, chromium precipitation, creep, fatigue.
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.
- Kugftukuy
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.
- Anti-corrosion coatings and cladding.
- Non-destructive testing.
- Risk Based Inspection.
