Corrosion Resistant Coatings.

By Philip Dawson MBA, Technical Advisor, Northpoint Ltd

Why Choose FBE and ARO Coatings?

FBE and ARO coatings are two corrosion-resistant coatings that are used to protect pipelines in various industries. Corrosion is a significant issue for pipelines as it can lead to structural damage, leaks, and failures. Therefore, FBE and ARO coatings are used to protect pipelines against the corrosive effects of water, chemicals, and gases.

FBE, or fusion bonded epoxy, is a coating that is applied to the surface of the pipeline through either a fluid bed dip process or electrostatic powder spraying process. The coating provides excellent corrosion resistance by creating a barrier between the pipeline and the surrounding environment. The coating is resistant to abrasion and chemicals, making it suitable for transportation of substances such as crude oil, gas, and water. FBE coatings have been widely used for pipelines in the Oil & Gas, Chemical Processing, Water Transmission and Marine Industries.

ARO, or Abrasion Resistant Overlay, is a coating that is applied to the FBE coating to provide additional protection against abrasion. ARO coatings are preferred for pipelines in industries like mining, timber, and construction drilling where there is a higher risk of mechanical damage to the pipeline. Unlike FBE, ARO coatings are made of liquid epoxy, which is sprayed onto the FBE coating to create a layer that is resistant to wear and tear.

Both FBE and ARO coatings offer excellent corrosion and abrasion resistance, making them an ideal choice for pipelines in various industries. The two coatings can also be used together for pipelines that require high levels of protection against both corrosion and abrasion.

In summary, FBE and ARO coatings are two types of coatings used for pipelines in various industries. While FBE provides excellent corrosion resistance, ARO provides additional protection against abrasion. Pipeline owners should seek professional advice to determine which type of coating best suits their pipeline’s needs.

What’s the Process?

The process for applying fusion bonded epoxy (FBE) and Abrasion Resistant Overlay (ARO) coatings to pipelines and fittings typically involves several stages. Here I give you an overview of the basic steps involved in the coating application process:

  1. Surface Preparation: Before applying the coatings, the pipeline surface must be prepared to ensure proper adhesion of the coatings. This involves removing any contaminants, such as rust, oil, or dirt, using mechanical cleaning methods or surface blasting.
  2. Preheating: The pipeline is preheated to a specific temperature to ensure proper adhesion of the coatings. This step involves heating the pipeline and fittings by heat soaking them in an oven.
  3. FBE Coating Application: FBE coating is applied to the heated pipeline or fitting surface using a fluid bed dip process or an electrostatic spraying process.
  4. Curing: After application, the FBE coating is cured by the residual heat in the part or heating the part to a specific temperature for a set period. This step ensures that the coating forms a stable and durable bond with the pipeline or fitting surface.
  5. ARO Coating Application (Optional): If additional abrasion resistance is required, an ARO coating can be applied after the FBE coating is cured. The ARO coating is applied using a plural-spray gun, and the pipeline or fitting is heated once again to ensure proper curing.
  6. Testing: Once the coatings are applied and cured, the pipeline or fitting is tested to ensure that the coatings meet the required standards for thickness, adhesion, and corrosion resistance.


Applying FBE and ARO coatings to pipelines and fittings requires specialised equipment, trained personnel, and strict adherence to quality, safety, and environmental regulations. It is essential to work with a coating supplier and applicator who have experience with these coatings’ application processes to ensure that the coatings are applied correctly and provide the required protection for the pipeline and fittings.

If you’re looking for a corrosion protection applicator with the experience, equipment and expertise then get in touch. From April 2024, Northpoint will be in a position to offer on pipes and fittings up to 12 m randoms, DN 300 – DN 2000 (larger by agreement).
