Effective pipe coating selection extends the pipeline lifetime

Industrial pipe coating products are developed to protect the interiors and exteriors of pipes without letting the internal lining affect the substance delivered by the pipe. 

Choosing the right coating, which matches the purpose of the pipe and its location, is crucial to guarantee the longest possible lifetime for the line pipes.  Long lifetime and minimum maintenance are important due the fact that the pipes are usually difficult to access.

The 6 properties an industrial pipe coating must have

Industrial pipe coating is ideal for protecting pipelines from corrosion but it is also thermally insulating. Next to these two properties, a pipeline coating should meet the following requirements.

  1. Absolutely resistant to corrosion
  2. Thermally insulating
  3. Allows suitable service temperatures
  4. Adheres well
  5. Is impact resistant
  6. Repairing it is easy

Industrial pipeline coating systems result from multiple coatings

An industrial pipeline coating system is never one coating, rather than a combination of coatings which together protect the line pipes from whatever hazard they may face.

Cathodic protection offers the initial protection

Cathodic protection is an effective way to prevent corrosion on industrial pipelines.

The first coating to be applied on the pipes provides cathodic protection. This means that the metal pipes are coated with another metal that corrodes faster than the substrate. The most common method that provides cathodic protection is galvanizing, which means that the pipe is coated with molten zinc.

Powder or liquid coatings enhance protection

After galvanising the pipes they receive another coating layer, which can be either powder or liquid coating. The powder coatings are usually Fusion Bonded Epoxies which are impact and abrasion resistant and flexible. FBE coatings are suitable for the most challenging operating environments.

The liquid industrial pipe coatings can be made based on various resins including:

  • Epoxy siloxane coatings for thermal insulation
  • Polyurea and polyurethane coatings for fire protection, thermal insulation and corrosion protection

Sometimes industrial pipeline coating is applied as a multi layer system which consists of several coatings. These systems can be based on two resins depending on the application:

  1. Polyethylene (PE) in 3LPE coatings (3-layer polyethylene coating)
  2. Polypropylene (PP)

The choice between these two is usually made based on the required operating temperature durability. In general, polypropylene coatings are more resistant to temperatures.
