Pipelines can be found in the foundations of almost any kind of infrastructure, they help in carrying liquids of all kinds from one place to another, but there is a lot more to a pipeline then simply connecting pipes and filling them up with substances. There is a wide range of pipelines out there, all of which have their own uses and work in their own way, some of the more complicated types of pipelines includes pressurized pipelines, these are pretty common since they allow for transportation of materials in a fast and effective manner.
However, there are various factors that one needs to keep in mind in order to ensure that a pressurized pipeline keeps on operating in an efficient manner, one of the biggest problems that a pressurised pipeline faces is when air bubbles start collecting inside of it. Trying to air proof a pipeline is expensive and often unfeasible due to various reasons, so you simply cannot stop air from creeping into the pipes every now and then. As air enters a pipeline it starts collecting in the form of air bubbles, this displaces the materials being transported and causes positive pressure to increase inside the pipes.
As a result, it becomes harder for pumps to push materials through the pipeline, making it less energy efficient and more prone to wear and tear due to the excessive strain being put on the equipment. In some cases, large amounts of air build-up can even result in a pipeline sprouting leaks or even bursting, this is why we have air release valves; they act as pressure release points that allow air to escape from the pipeline without causing any disruptions. Air release valves work in a very simple yet very effective manner and can be found on almost any kind of heavy duty pipeline that is used to transport large amounts of materials.
An air release valve consists of a buoy connected to a gate that shuts the valve’s vent, this buoy stays afloat when the pipeline is free of air bubbles, as air bubbles begin to collect in the pipeline, they start collecting inside the valve and push the liquid out of the valve. As the liquid level in the valve lowers, the buoy gradually begins to go down and after a certain point, it causes the valve vent to open and lets air escape from the pipeline.
Air release valves are placed in high points in a pipeline and in order to make the effective, their size needs to be picked correctly, a valve that is too big will not open at the right time and a valve that is too small might not be able to handle the pressure inside of the pipeline. Air release valves also need to be of highly durable and made with precision, like the industry leading Apco air release valve lineup that is well-known for its range and its superior performance that ensures release valves that can be counted on.
