The Importance of Pipeline Coating in Corrosion Prevention

Here are two facts worth noting:

One: Corrosion is the number one enemy of metal pipes.

Two: Pipeline coatings are the number one defense against corrosion.

According to the website Corrosionpedia, pipeline corrosion is the deterioration of pipe material that takes place as a result of its interaction with the working environment. Corrosion of most pipelines occurs due to an electrochemical reaction that takes place in the presence of an electrolyte.

Every pipeline system is susceptible to corrosion threats. Even a brand-new system can show signs of corrosive wear in as little as two years after installation if it is not coated. Therefore, choosing the right coating is crucial because it will help prevent corrosion and maintain pipeline integrity over the long-term.

An effective pipeline corrosion coating will have the following properties:

  • Good metal surface isolation - sufficiently isolates metal from the environment;
  • Excellent adhesion to the pipe – provides resistance to cathodic disbondment;
  • Water resistant - won't allow water to seep through to the metal surface;
  • High impact resistance - protects against and resist buffeting from boats and floating debris;
  • Flexibility - won't crack under the distortion of pipe bends or twists;
  • High electrical resistance - inhibits electrolytic corrosion and resists electrical current flow;
  • Bio-fouling résistance - isolates metal from marine life, fungus and scale attack.

Our pipeline coating product, SplashTRON, is an anticorrosive system based on advanced polychloroprene technology. It uses a high-density elastomer that resists weathering, fungus, marine life and most oils, and works with both onshore and offshore pipelines. It has particularly useful application for providing splash zone protection.

SplashTRON® consists of three layers that are vulcanized to the steel pipe surface.

  1. The first layer is a primer coat that provides the pipe surface with a film that resists chemical attack and cathodic disbondment.
  2. The second layer bonds the first layer and top coat.
  3. The third layer provides both anticorrosive and mechanical protection.

The system can be bonded to pipe of practically any length in diameter, and to virtually any degree of thickness, 1/4", 1/2", and 1" being the most common.

SplashTRON® completely and permanently bonds to the metal surface and won't crack or disbond as pipes bend, expand, and contract.
