Various Types Of Methods Used In Pigging A Pipeline

By Kenneth Sullivan


Pipelines have been basically major means of transport of some liquids. The method has been very effective in reducing the number of accidents that may occur when any other means of transport is used for the same. Some of major products or goods transported via this means include petroleum products, steam, RPG gas and water amongst others. The method is as well very prone to a number of damages if the entire channel or system is not maintained. Some problems or issues related to these damages include corroding and bursting. This vital method has been one of the best methods that have been recently used to avoid such damages and therefore, for this reason, there is the great need for the knowledge on the various types of used in pigging a pipeline.

In the description, pigs are devices that are commonly inserted in the pipes to detect and correct the various damages that may affect the smooth functioning of transportation pipes. There are different types of pigs that can be used that are used differently but with the main aim of keeping the pipeline system in a good running condition.

The method of pigging was invented with the purpose of cleaning the inner side of such pipes alongside scraping out any kind of deposits and rust that has accumulated on the inner side of pipes. With the recent technology, the method has as well been used to measure out the diameters of many pipes, detecting leakages and also detecting any part of the pipes that has been worn out.

Secondly, pigging can also be used to clean the inside part of such pipes. Scale and rust are some of those most common debris that may form on the inside of pipes. The wax may as well build up in the transportation of paraffin and other petroleum products. In the transportation of gasses, they may condense as it cools and therefore, reducing the efficiency in the flow of some gasses. For this reason, the pipes require being regularly cleaned to help facilitate a smooth running of the various products.

The above-mentioned method work by the combination of a magnetic flux leakage and ultrasonic that helps to gather information from the pipe. They both work differently to generate the information with the magnetic flux working to detect any leakage and collection from the pipes. The ultrasonic on the other hand work to detect and measure the thickness of the pipes.

To help propel the pigs inside these pipes, they are loaded in a pig launcher. With the help of pressure of flowing fluid being driven into these pipes, the launchers are driven to the receiving end where they are collected having collected the entire information in the pipes.

Gel pigging is as well very efficient in the pipeline system. The type of method works to separate the various products from the pipeline. It can also be used to remove debris as well as any stuck pig inside the pipes.

The various pigging method has as well been designed for all the diameters of the pipes. All that is needed is to have the knowledge on the best method that will help fix a specific damage in pipes.
