Why Fusion bonded epoxy Coating Is Essential for Pipeline Protection?
- Superior Corrosion Resistance
· Unlike traditional coatings, Fusion Bonded Epoxy coating forms a non-porous barrier, preventing moisture and chemicals from reaching the steel.
· It is widely used in oil & gas pipelines, water transmission, and subsea applications. - Long-Term Durability
· FBE-coated pipes can last decades with minimal maintenance, reducing lifecycle costs.
· It resists cathodic disbondment, a common failure mode in pipeline coatings. - Environmental & Safety Benefits
· Zero VOCs – Unlike solvent-based coatings, FBE is environmentally friendly.
· No cracking or peeling – Ensures safe operation in high-pressure systems. - Compliance with Industry Standards
FBE coatings meet stringent standards, including:
· ASTM A307 (Mechanical Testing)
· NACE SP0492 (Pipeline Corrosion Protection)
· ISO 21809-2 (External Coatings for Buried/Submerged Pipelines)
Applications of FBE Coated Steel Pipes
Below are the main application fields of FBE coated steel pipes:
- Oil and Gas Industry
FBE coated steel pipes are commonly used in the oil and gas industry for the transportation of crude oil, natural gas, and refined petroleum products. Their excellent corrosion resistance makes them ideal for use in both onshore and offshore pipelines, where they are exposed to harsh environmental conditions such as saltwater, soil, and various chemicals. These pipes are often used for:
Crude oil and gas transportation
Offshore pipeline systems
Subsea pipelines - Water Supply and Wastewater Systems
FBE coated steel pipes are extensively used in the water supply and wastewater treatment sectors due to their ability to resist corrosion caused by water, soil, and chemical pollutants. They are used in both drinking water distribution systems and wastewater transport systems. Applications include:
Drinking water pipelines
Sewer and wastewater pipelines
Stormwater drainage systems - Chemical and Petrochemical Industries
In the chemical and petrochemical industries, FBE coated steel pipes are used for transporting a variety of aggressive chemicals and fluids that may cause corrosion in conventional steel pipes. The coating provides reliable protection, ensuring the integrity of the pipelines. Typical applications include:
Chemical transport pipelines
Refinery process lines
Petrochemical plant systems - Mining Industry
The mining industry relies on FBE coated steel pipes for transporting slurries, minerals, and other corrosive materials. The pipes are particularly useful in harsh mining environments where both physical and chemical corrosion are concerns. Applications include:
Slurry transport pipelines
Mine dewatering systems
Mineral processing pipelines - Marine and Subsea Applications
FBE coated steel pipes are ideal for subsea pipelines used in offshore oil and gas exploration, as they provide superior protection against corrosion caused by saltwater and other marine elements. They are used in:
Subsea oil and gas pipelines
Offshore riser systems
Underwater gas and water transport pipelines - Power Generation Industry
In the power generation industry, FBE-coated steel pipes are used in cooling water systems, steam transport lines, and other areas where corrosion resistance is crucial for the safe and efficient operation of power plants. Typical uses include:
Cooling water pipelines
Steam transport pipelines
Waste heat recovery systems - Infrastructure Projects
FBE coated steel pipes are used in various infrastructure projects, such as urban water distribution systems, district heating systems, and sewage treatment plants. Their ability to withstand corrosion in buried or submerged conditions makes them highly suitable for:
Urban infrastructure
District heating pipelines
Sewage treatment plant systems - Agricultural Irrigation
FBE coated steel pipes are also used in agricultural irrigation systems, providing long-lasting protection against corrosion from soil and water exposure. Applications include:
Irrigation pipelines
Water distribution systems for agriculture
How to Choose the Right FBE Coated Steel Pipe?
- Environmental Conditions
One of the most critical factors in selecting the right FBE coated steel pipe is understanding the environmental conditions to which the pipe will be exposed. This includes:
Soil Type: For underground applications, the soil’s moisture, pH, and chemical composition can influence the corrosion resistance of the pipe. In more aggressive environments, a thicker or higher-quality FBE coating may be necessary.
Exposure to Water or Saltwater: If the pipeline is underwater or exposed to high humidity or saltwater, the coating must be highly resistant to corrosion caused by these factors, ensuring durability and reliability.
Temperature: The pipe’s exposure to high or low temperatures can affect the FBE coating’s performance. High-temperature applications require coatings that can withstand higher temperatures without degradation. - Pipe Size and Thickness
The size and thickness of the steel pipe affect the coating’s application process and the required coating thickness. Larger pipes or those with thicker walls may require specific coating methods or additional layers of FBE to ensure even coverage and adequate protection.
Standard Sizes: Make sure the FBE-coated steel pipe meets the required industry standards and pipe dimensions for the specific application.
Thickness: The thickness of the coating should be chosen based on the expected environmental and mechanical stresses. For more aggressive environments or heavy-duty applications, a thicker coating (typically between 300 to 500 microns) may be needed. - Chemical and Fluid Compatibility
If the pipe will transport chemicals, gases, or liquids, the compatibility between the FBE coating and the transported medium must be considered. The epoxy coating should be able to resist the corrosive properties of the fluid being transported.
Chemical Resistance: FBE coatings offer good resistance to a wide range of chemicals, but for highly aggressive fluids, it may be necessary to use a specific grade of FBE coating designed for that particular chemical environment.
Internal vs. External Coating: For pipes transporting aggressive fluids, an internal FBE lining may be necessary, while external coatings will help protect the pipe from environmental corrosion. - Coating Quality and Standards
Ensure the FBE coated steel pipe complies with the relevant industry standards and quality specifications to ensure its performance.
Industry Standards: Check for adherence to standards such as ISO 21809, AWWA C213, and DIN 30670, which define the requirements for FBE coatings in various applications, including coating thickness, adhesion, and inspection procedures.
Quality Assurance: Verify that the pipe manufacturer follows proper quality control practices, including coating thickness measurements, adhesion testing, and visual inspections to ensure the coating is uniform and free of defects. - Mechanical Stress and Impact Resistance
The pipe should be able to withstand mechanical stresses, such as impacts during handling, installation, or operation. FBE coatings provide excellent mechanical damage resistance, but for applications involving high external forces or heavy traffic areas, additional considerations may be needed:
Impact Resistance: Choose a coating that provides excellent adhesion and can resist cracking or chipping when subjected to external forces.
Abrasion Resistance: For pipelines in areas prone to abrasion, a thicker or modified FBE coating may be needed to prevent damage. - Application Method
The method of coating application is another important consideration when selecting FBE coated steel pipes.
Spray vs. Fluidized Bed: FBE coatings can be applied using different methods, such as electrostatic spray or fluidized bed. The method selected depends on the pipe’s size, the coating’s desired thickness, and the production capacity.
Curing Process: Ensure the pipe is properly cured after coating to ensure the epoxy resin fully bonds to the steel and achieves the required durability. - Cost Considerations: While FBE coated steel pipes offer excellent protection, the cost may vary depending on the pipe size, coating thickness, and environmental conditions. It is essential to balance the need for durability with the budget for the project. In some cases, opting for a thicker or more advanced FBE coating may be a better long-term investment, reducing maintenance and replacement costs.
- Supplier Expertise: Choose a reliable supplier with expertise in FBE coating technology. A good FBE steel pipe supplier can provide guidance on the appropriate coating type, help with coating selection based on environmental conditions, and offer certifications to confirm that the coatings meet the required standards.
