Definition - What does Pipeline Coating mean?
A pipeline coating is a cost effective and viable solution to maintain pipelines' integrity. This coating provides a constant protective lining that helps save pipelines from the damaging effects of corrosion. Pipeline coating is one of the most reliable corrosion prevention methods used by industries today.
Corrosionpedia explains Pipeline Coating
Pipeline coatings are typically applied to counter the negative effects of corrosion on pipeline operation, capacity and costs.
Uncoated pipelines that are submerged in seawater are prone to corrosion. Although the corrosion debris from these pipelines can be removed, the disposal of these fragments can be detrimental to the environment. Therefore, strict regulations have been implemented, including the practice of applying pipeline coatings. This prevents the formation or reformation of corrosion. Pipe coating application is considered a standard practice and provides the following benefits:
- Improved gas flow - A smoother surface results in enhanced flow capacity. Various studies have demonstrated that flow capacity of coated pipelines is far better than uncoated ones.
- Faster inspection and commissioning - Coated pipework dries faster than uncoated pipes. This means that commissioning can be faster and easier on the line. Any type of robotic inspection is also simplified with the enhanced mobility of equipment through a coated pipeline.
- Decreased cost of energy - This is especially true in terms of compressors and pumping stations. Pipelines that are internally coated could create a vast difference in lowering the costs of compression and pumping over the pipe’s lifespan. This can possibly increase financial payback in three to five years, which means significant savings.
Other than these benefits, pipeline coating can also reduce the need for inhibitors and promote clean delivery of the product. Thus, this can serve as a cost-effective and low-maintenance option for corrosion control that offers ample and reliable protection.
