Knowledgeable Things In Relation To Pigging A Pipeline

By Kenneth Sullivan


Petroleum products, various types of gasses and steam among other products are the commonly known products to be transported through piping. The method is the most efficient one for the transportation of these fluids since large volumes of products or goods can be transported within a shorter period than any other of methods or means available. The method is as well very important in reducing the risks and accidents during the transportation. More to this, the method is also very prone to damages and therefore, for this reason, the entire pipeline system requires to be regularly inspected to fix any kind of possible damages. Such a method has been the commonly used method for such kind of inspection. In relation to this, there is the great need of the knowledge on some tips related to pigging a pipeline.

Utility pigs have been one of these methods. This specific method has been used to do away with any unwanted materials including wax and scum from the pipeline system. The pigs work by being inserted into the pipe and with the recent technology the unwanted materials are removed.

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.

There are quite a number of pig techniques used all with the main aim of maintaining the smooth running of all pipeline products. Some of these methods include the inspection pigging, utility pigs, gel pigs as well as specialty pigs.

To sum up the above-mentioned information, the various methods can be combined to ensure a smooth running of the products in the system. They as well come with varying diameters to cater for the various sizes of pipes used in the system. Therefore, all you need is the knowledge on how to initiate the process of pigging the pipelines.
