ISO 21457:2010 is officially titled:
"Petroleum, petrochemical and natural gas industries — Materials selection and corrosion control for oil and gas production systems"
This standard provides recommendations and requirements for selecting metallic materials and establishing corrosion control methods for use in oil and gas production systems, especially under wet hydrocarbon production conditions.
Key applications include:
In oil and gas operations, corrosion is a persistent threat that affects safety, reliability, and cost-efficiency. Improper material selection can lead to:
⛽ Pipeline leaks and ruptures
🔥 Equipment failure and safety incidents
💸 Expensive downtime and repairs
❌ Non-compliance with safety regulations
ISO 21457 helps engineers and project managers evaluate the environmental conditions, identify corrosive threats (such as CO₂, H₂S, chlorides, temperature, and pressure), and select appropriate materials and corrosion control measures accordingly.
Implementing ISO 21457 ensures a systematic approach to material and corrosion risk management in oil and gas production:
🧪 Structured Material Selection Process
Considers factors like corrosion rates, compatibility, pressure, temperature, and service life.
🛡️ Corrosion Mitigation Guidance
Recommends protective coatings, inhibitors, cathodic protection, and corrosion-resistant alloys (CRAs).
🏭 Applicable to Various Production Systems
Covers topside, subsea, onshore, offshore, and downhole applications.
📊 Supports Lifecycle Cost Analysis
Encourages long-term decision-making over upfront cost reduction.
🛠️ Works With Other Industry Standards
Complements ISO 15156 (NACE MR0175) for sour service material use.
By implementing ISO 21457 with GMC’s expert support, your business can:
✅ Reduce Corrosion-Related Failures
Avoid costly shutdowns and repairs due to premature equipment failure.
✅ Improve Asset Integrity and Safety
Strengthen the reliability of critical systems in harsh operating conditions.
✅ Comply with Regulatory Requirements
Meet operator, government, and HSE expectations for safety and design standards.
✅ Optimize Material Costs Over Lifecycle
Choose materials that balance performance, longevity, and total cost of ownership.
✅ Increase Operational Efficiency
Minimize maintenance and unplanned interventions due to corrosion.
✅ Support Risk-Based Design and Engineering
Enhance front-end engineering and design (FEED) phases with better material data.
