Coatings and Linings

Coatings and Linings for Tanks, Terminals and Pipelines

Tanks, terminals, and pipelines are the backbone of the oil and gas industry, responsible for the safe storage and transportation of crude oil, refined products, and chemicals. However, these assets are constantly exposed to corrosion, chemical attacks, extreme weather conditions, and mechanical stress. Without proper protection, their structural integrity can degrade over time, leading to operational failures, costly repairs, and environmental hazards. Coatings and linings serve as the first line of defense, preventing deterioration and ensuring long-term performance. In this article, we explore their importance, types, leading paint brands, application methods, and maintenance best practices to enhance the durability and safety of oil and gas infrastructure.

1. The Role of Coatings and Linings in Oil and Gas Infrastructure

Why Are Coatings and Linings Necessary?

Corrosion Prevention – Protects metal surfaces from rust and oxidation due to moisture, salt, and chemicals.
Kháng hóa chất – Shields tanks and pipelines from aggressive fuels, acids, and solvents.
Abrasion and Wear Protection – Reduces damage from high-velocity fluids, sand, and particulates.
Chống tia UV và thời tiết – Ensures durability in harsh environmental conditions.
Compliance with Industry Standards – Meets API, NACE, ISO, and ASTM regulations.

2. Types of Coatings and Linings for Tanks, Terminals, and Pipelines

A.External Coatings for Pipelines and Tanks

External coatings protect assets from atmospheric exposure, soil stress, and physical damage.

1. Fusion-Bonded Epoxy (FBE) Coating

🔹 Đặc trưng: Corrosion resistance, strong adhesion, high durability.
🔹 Best for: Buried pipelines, subsea pipelines, above-ground storage tanks.

2.Three-Layer Polyethylene (3LPE) & Three-Layer Polypropylene (3LPP) Coatings

🔹 Đặc trưng: High mechanical strength, resistance to temperature fluctuations.
🔹 Best for Underground pipelines in extreme soil conditions.

3. Polyurethane (PU) Coating

🔹 Đặc trưng: UV-resistant, flexible, high mechanical impact strength.
🔹 Best for Above-ground tanks and exposed pipelines.

B.Internal Linings for Oil Storage Tanks and Pipelines

Internal linings prevent corrosion from stored fluids, improve flow efficiency, and extend asset lifespan.

1. Epoxy Linings

🔹 Đặc trưng: Excellent chemical resistance, smooth surface for easy cleaning.
🔹 Best for Crude oil tanks, petroleum pipelines, and water storage.

2 . Glass-Flake Coatings

🔹 Đặc trưng: Reinforced with glass flakes for superior abrasion and corrosion resistance.
🔹 Best for Tanks and pipes handling aggressive chemicals and high temperatures.

3. Polyurea Linings

🔹 Đặc trưng: Fast-curing, flexible, impact-resistant, waterproof.
🔹 Best for Secondary containment areas, tank bottoms, and emergency repairs.

4 . Rubber Linings

🔹 Đặc trưng: Outstanding chemical resistance, flexible, impact-absorbing.
🔹 Best for: Tanks storing corrosive fluids, acids, and wastewater treatment.

4. Coating Application Methods

🛠 Spray Application – Used for epoxies, polyurethanes, and polyurea coatings.
🛠 Brush & Roller Application – Suitable for small areas and touch-ups.
🛠 Dip Coating – Ideal for pipeline sections before installation.
🛠 Thermal Spray Coating – For metal-based coatings like zinc and aluminum.

👉 Surface Preparation is very important: Proper cleaning, abrasive blasting, and priming ensure strong adhesion and long-lasting performance.

5. Inspection, Maintenance & Best Practices

Regular inspections and maintenance ensure that coatings and linings remain effective:

✔️ Kiểm tra thường xuyên – Use ultrasonic testing, magnetic flux leakage, and visual checks.
✔️ Cathodic Protection (CP) – Works alongside coatings to prevent electrochemical corrosion.
✔️ Recoating Schedules – Plan maintenance to reapply coatings before deterioration begins.
✔️ Emergency Repairs – Fast-curing polyurea coatings provide quick, effective fixes.

MỘT proactive maintenance approach helps maximize asset longevity, reduce costs, and improve operational reliability.
