What Pipe Coating is Needed for Oil & Gas Pipelines?

oilandgasThe current protective coating technology for oil and gas pipelines is viewed to have technical and economic disadvantages. Several factors contribute to the complexity of designing efficient pipeline coating formulations, including climate, properties of the substrate traveling through the pipeline, product flammability, as well as the rate of flow. It must be taken into consideration that if the pipeline is underwater, or either underground or above ground, the coating must be formulated to provide long term internal and external durability. Some factors contributing to the complexity of pipe coating are addressed below:

  • Climate, temperature, and physical location of the pipeline. A company needs to be sure they acquire pipe coating that can be applied, function, and withstand diverse climates. As mentioned previously, pipelines can be run underground, underwater, or above ground, and each installation application presents its own unique pipeline coating challenges.
  • The physical state of fluid transported through the pipeline. Liquid and gaseous fuels are not harvested in a clean state; meaning impurities are present during harvesting. When flowing at high speed through a pipeline, these particulates become abrasive. Professional pipe coating companies will offer highly resistant formulations to the corrosive nature of a variety of particulates at high flow rates or to liquefied natural gas, which is transported at cryogenic temperatures.
  • Efficient pipeline coatings need to be appropriate for a wide range of fluid viscosity.
  • Both the fluid in the pipeline and the coating material before curing might be extremely flammable. Many current coating methods require application of open flame, subsequently creating a potential fire hazard at the work site. A company in need of pipe coating should try to find nonflammable formulations.

Pipe coating for oil and gas pipelines must be divided into two separate categories, each with its own unique and demanding requirements – internal and external coatings. Concerning internal coatings, oil and gas fluids contain solid particulates. Some of the particulates will dissolve in the fluid, while some will remain in suspension. Traveling through pipelines at considerably fast speeds, these particulates become aggressively corrosive projectiles. Coatings designed for internal pipeline application must be engineered to withstand the high impact created by these fast moving particulates. Pipe coatings designed for external pipeline applications must be engineered to withstand the wide variety of environmental conditions previously mentioned. Many outside elements present formidable challenges to the performance of external pipe coatings; therefore, external coatings also need to be resistant to practically any extraneous force, including the chemicals and solvents used in the processing of the hydrocarbons.

Because the provided information likely sounds quite complex, it is recommended you seek the assistance of a professional company offering pipe coating for oil and gas pipelines.
