Pipeline corrosion alone costs the U.S. economy more than $9 billion each year. There are four main types of corrosion for which oil and gas plants have to be on the lookout: weight loss corrosion, corrosion fatigue, galvanic corrosion caused by currents (which occur due to a mixture of metals), and stress corrosion (cracked pipes). But what can be done to help avoid corrosion in oil and gas pipelines?
Stainless Steel Flange Fittings
Less prone to corrosion than other materials, stainless steel flange fittings are a great first line of defense against many types of corrosion. Stainless steel flange fittings can be used in a variety of situations. This flexibility also makes them a good choice for the construction phase of preventing corrosion in oil and gas pipelines.
Oils and Greases
Using lubrication on the inside of pipes can help prevent the build-up of rust and the subsequent corrosion of metal. Many of the oil-based rust removers available are also safe for plastics and rubber, so there’s no need to worry about over-spray. That said, it is important to make sure that the lubricant you’re using is safe for use with the gas or oil you’re exporting.
Epoxy is a high-quality coating material that is ideal for coating steel pipelines. Corrosion can occur when pipelines are exposed to warm temperatures, as well as to the soil and water found in natural environments. A coating provides a barrier between the pipe’s surface and the elements. This is an especially strong option if your pipes are going to be used in diverse areas.
Inspection and monitoring are critical to maintaining the structural stability and overall safety of oil and gas pipelines. While numerous lines cannot be realistically inspected in-person on a routine basis, inspection systems do exist which employ an array of piezoelectric sensors to detect any issues with the pipelines.
Ultimately, the prevention of corrosion comes down to not only construction and inspection, but to rigorous testing of all equipment used, as well. Utilization of the ideal parts for the job can only help.
