Things To Know About Pipeline Pigging
Any buildup in a pipeline potentially causes transmittal slows and even plugging of the pipeline. Flaws and cracks in the pipeline can also be disastrous, and finding ways to mitigate this effectively can readily be appreciated. If you can get some form of slow assurance gas and oil flowlines and pipelines, you can minimize and even eliminate the chances of transmittal slows and plugging. That is where pipeline pigging comes in to enhance the smooth running of the line.
Pipeline pigging is the process of introducing maintenance tools referred to as pipeline pigs into the line through what is called a pig trap. The pig trap is made up of a launcher and receiver. Without interrupting the line flow, the pig is put forcefully through by-product flow. The pig trap can also be towed by a separate cable or device. In most cases, the line pigs are spherical or cylindrical and shape, and they sweep the sides of the pipeline by scraping its sides and taking the debris forward. The pig help in a number of ways along the pipeline, such as clearing the pipeline and inspecting the interior of the pipeline.
There are two notable hypotheses to explain why the process is referred to as pipeline pigging, even though both of them are yet to be proven. Some pipeline experts hold that the word pig is an abbreviation for Pipeline Intervention Gadget. The other theory explains that some leather-bound pig would be sent through the pipeline, and as it passed, the leather around them would squeak against the pipeline sides in what sounded like a squealing pig. The pipeline engineers need to consider a few factors when looking for the right pig for the pipeline they are working on.
To start with, you must define the specific purpose of the pig in the establishment. You should also consider the operating conditions and size of the pig before buying it. The other important consideration when selecting the right pig is the pipeline layout. Every pipeline is different, and most of the time, there is no specific schedule to undertake pipeline pigging. The quantity of the debris collected in the pipe, however, increases the frequency with which pigging is done. These days pipeline pigging is used during almost all phases of the lifespan of the pipeline.
While pipeline pigging was originally used to clear piping systems, the purpose of the procedure has evolved with technological advancement. There are now utility pigs which are designed to be inserted into the pipes to remove all the wax and other unwanted materials in the line. The utility pigs are similar to cleaning the plumbing line as they help in the removal of debris from the pipes as well as sealing the line. There are also inline inspection pigs, whose main purpose is to examine the inside of the pipes. Specialty pigs, on the other hand, are used for isolating specific areas and cleaning them. You will also find gel pigs, which are literally a chemical pigging system. Choose a pipeline pigging that meets your needs.
