The pipelines beneath the ground are crucial to the functionality of a town’s waste management and water systems. Corrosion is a common issue in metal pipes. It threatens the integrity of the metal, which could cause the town’s pipe network to fail, stop, or potentially harm anyone working with or using the pipeline. Listen to our advice to ensure you’re preventing corrosion on the pipelines in your town.
It might seem difficult to keep the pipes clean when liquid or water constantly runs through them. Some of these substances carry corrosive bacteria, which causes microbiologically-induced corrosion.
Cylinder-like devices known as “pigs” can help clean the inside of pipes to clear away bacteria and ensure optimal flow. Pigs come in many types, such as utility, gel, and inspection versions. Ensure you’re finding the right one for the job you need. For instance, gel pigs are ideal for normally “unpiggable” lines.
Various protective features, such as coatings or linings inside the pipeline, can help protect the metal from premature corrosion. For example, if electrochemical corrosion is an issue, try cathodic protection. This uses an electrical current to replenish lost electrons in the metal. You might also use fusion-bonded epoxies to prevent chemical corrosion. Adding an extra layer of protection inside the pipeline is one of the best ways to prevent corrosion.
The more friction and rubbing against surfaces a pipe endures, the more quickly it will begin to wear and corrode. Using U-bolts, clamps, straps, etc., you must keep the pipes stable beneath the ground to prevent friction and vibrations.
Furthermore, some metals don’t mix well together when they’re touching. When one metal pulls electrons from another, it’ll encourage galvanic corrosion. Consider insulating the pipe to place a buffer between the two types of metals to prevent them from touching and corroding.
When you’re working on a pipeline and notice a large area of corrosion, this could be a sign that you need emergency pipeline services. The best way to prevent corrosion is to stop it at its source. Don’t let it set in. Clean the pipeline regularly, add protection with coatings, and insulate pipes to prevent metal-to-metal contact.
