What is Intergranular Corrosion and How Does it Occur?
Intergranular corrosion is one of many fascinating forms of corrosion in the world around us. In the oil and gas industry, intergranular corrosion is a potential threat like no other. This form of corrosion is caused by the presence of impurities within a substrate. When an alloy experiences the process of solidification, it creates grain boundaries. This is exactly where intergranular corrosion begins to form. What happens next is potentially harmful. Intergranular corrosion takes shape adjacent to the grain boundaries and when this occurs, any mechanical properties that are present are negatively affected. What do these negative affects look like? Intergranular corrosion will leave behind pressure cracks and grooves. Luckily, there are some sure proof ways of defending against intergranular corrosion.
How to Prevent Intergranular Corrosion
There are several methods to keep intergranular corrosion from harming infrastructure and equipment. Regular cleaning of surfaces is a cornerstone method of warding off this type of corrosion. In addition to keeping a regular cleaning schedule, surface preparation represents another method of corrosion prevention. Surface preparation allows for coatings to maintain their integrity and longevity. Drying agents, coating barriers, and backfill layers are a few more of the proper routes of defense against the harm that intergranular corrosion can bring.
