Pipe Coating

Pipe coating is the process of applying a layer of protective coating on the surface of a piping system. Piping systems in the industry usually have to transport a large amount of fluid, ranging from water and oil to gasses like waste gas from industry. Hence the nature of the fluid, as well as the dynamic friction caused during the flow of the fluid in the piping system, will eventually alter the surface quality of the pipes and may lead to rusting metal. Corrosion in pipeline systems such as pitting corrosion and crevice corrosion often occurs due to electrochemical reactions in the presence of electrolyte and the rate of corrosion directly relates to the external and internal factors. The external factors are the working environment of pipes like moisture in the soil whereas internal factors are reactivity of fluid and oxygen content. What actions could be taken to prevent the deteriorating state of the piping systems after a time period?

That is the reason why pipeline coating is applied on the surface of pipelines to prevent rusting and corrosion from happening, thus saving you unnecessary cost to replace them. Both landed pipelines as well as underground pipelines are required to be coated as they are prone to chemical reactions. Besides, internal and external surfaces of the pipelines have to be applied coatings too to the different working environment will cause a different level of harm to your pipelines. The benefits of giving your piping systems the right amount of protection through pipeline coatings are:

• Improvement in fluid flow inside the pipelines. Coated internal pipelines will have a smoother surface and hence enhance the flow capacity of the fluid, ranging from oil to water.
• Faster drying process. Pipelines coated with appropriate coating materials will dry faster compared to uncoated pipelines. This will also make the inspection of and testing of the pipelines easier to be carried out to search for leaks and cracks, typically stress corrosion cracking.
• Reduced cost of energy. Since coated piping will allow higher flow capacity of fluid, the cost of compression and pumping will also reduce as well increasing cost efficiency.

Various types of pipeline coatings could be applied to protect your pipeline systems for example coal-tar enamel coatings, plant-applied tape systems, epoxy, metallic spray coatings, polyolefin with butyl adhesive and others where each of the coatings has their pros and cons depending on the purpose and time period the coating is applied.
