Pipeline corrosion is one of the biggest challenges that oil and natural gas pipelines have to face lately. For any mechanical project company, maintaining corrosion poses a tough challenge that can potentially cost a lot of money.

What are pipelines?

Pipelines are, in a way, similar to the arteries and veins in our human body. They are present underground and carry oil and several natural gases for several kilometers at a stretch! And, just like damage in any of our artery or vein will severely harm our body, corrosion (or damage) in a pipeline is just as bad for oil pipelines, damaging their working principle thoroughly.

What causes corrosion?

Corrosion is a natural process of degradation to an embedded pipeline. The main reason why it happens is the transformation of refined and unstable steel to its natural iron ore state, after the reverse has happened, which requires a lot of energy.

Corrosion also happens due to two metals (e.g., steel and copper) with different potential connecting in a common environment, causing a current to flow. Moreover, stress causes corrosion, too, when any and every small pit turns to metal under stress. Another cause of corrosion is hydrogen embrittlement, when atomic hydrogen produces cracks in steel.

How to maintain them?

For piping construction companies in India, there are certain ways to maintain pipeline corrosion. Some of the tried and tested, successful methods for controlling corrosion are coating, cathodic protection, electrical isolation and overall proper maintenance of the pipeline. All these methods are done beforehand, while construction, to delay the inevitable damage of the pipeline for as long as possible, especially by electrical isolation.
