ISO 21809 is a comprehensive standard series titled:
“Petroleum and natural gas industries — External coatings for buried or submerged pipelines used in pipeline transportation systems”
This standard is divided into multiple parts, each specifying requirements for different types of coatings and pipeline conditions, such as:
| PartFocus Area | |
| ISO 21809-1 | Fusion-bonded epoxy (FBE) coatings |
| ISO 21809-2 | Single-layer and multi-layer polyethylene/polypropylene coatings |
| ISO 21809-3 | Field joint coatings |
| ISO 21809-4 | Polyurethane and polyurea coatings |
| ISO 21809-5 | External concrete coatings |
| ISO 21809-6 | Internal coatings for corrosion control |
| ISO 21809-7 | Coatings for high-temperature applications (above 100°C) |
Each part provides technical specifications, testing methods, performance criteria, and quality assurance requirements to ensure pipeline durability and corrosion protection.
Pipelines that transport oil, gas, and chemicals are subject to extreme environments — including moisture, soil chemicals, temperature fluctuations, and mechanical stress. Without proper coatings, risks include:
⚠️ Corrosion and leakage
❌ Downtime or service failures
💸 Costly repairs and environmental liabilities
🚫 Regulatory non-compliance
ISO 21809 ensures that coatings are correctly formulated, applied, tested, and verified to protect pipelines in the most demanding operating conditions.
Implementing ISO 21809-compliant coatings offers significant technical and operational advantages:
🛡️ Enhanced Corrosion Resistance
Provides a long-term protective barrier against soil, water, and chemical exposure.
⚙️ Extended Pipeline Life
Reduces degradation and need for frequent maintenance or recoating.
🧪 Standardized Testing Methods
Includes cathodic disbondment, adhesion, impact resistance, and coating thickness tests.
🌍 Compliance with Global Standards
Facilitates pipeline project approvals in international markets and joint ventures.
📈 Supports Safety and Environmental Goals
Minimizes leaks and spills, aligning with ESG and regulatory frameworks.
