In the course of maintaining pipelines, certain measures are taken. One of them is called pigging. This is whereby specially designed devices called pigs are used to execute various upkeep operations, without necessarily disrupting the normal flow of whatever product is inside the pipeline. Loading a pig into pipeline is usually used in activities such as cleaning as well as inspecting it.
Pigging, from a piping perspective, can be described as typically a process where pigs are used in performing various functions such as leak detection, inspections and cleaning. The pigs are inserted inside oversized sections called pig launchers or launching stations, and thereby reducing to regular diameter. The launchers are subsequently closed, and afterwards pressure-propelled flow of whatever medium inside the piping pushes the pigs through the pipes, all the way to the receiving traps.
For umpteenth years, pigging has usually been used in oil industries and other large plants to clean conduits especially those with large circumferences. Currently, there has been an upsurge in usage of smaller circumference pigging systems, across various batch plants and oil firms. This has been deemed as a move to revamp efficiency and also reduce overhead costs.
The pigging methodology can be used in basically myriad stages of batch processes, for instance blending, storing as well as filing and re-filling. Research has revealed that the process is majorly opted in industries dealing with diversified products or substances, the likes of oils, paint, chemicals, food, toiletries and many more.
There are other pigging devices that are used in inspecting conduit pipes, for the sole purposes of mitigating any possible leaks which may ultimately result in explosions and other hazardous ramifications. They do not hinder production in any way, but nonetheless, some of the product may be lost after the pigs are extracted. Pigging can also be done when separating different components in multiproduct conduit pipes.
It should be noted that pigging measures should not be undertaken recklessly, carelessly or with people that have scanty knowledge on the intricacies involved. This is because cases of deaths and severe injuries resulting from mishandling the systems have been on the rise. Caution and experience is therefore paramount. There are many mistakes that may result in catastrophes, though the commonest one is whereby the closure openings are open and at the same time the vessel is under intense pressure.
Another advantage is that pigging ensures the product is saved as much as possible, as well as time. This is because during the tail end of transfer process, the line can be easily cleared out in either directions, forth towards reception point, or back towards the source. Line flushing is therefore of no importance.
All the above mentioned causes are majorly related to unorthodox and improper operations of process valves as well as closure doors. Adding valve interlocks is a very clever idea of combating these woes. Adherence to all safety procedures are core during this process, and therefore make sure that you carry out all various activities involved in the process very cautiously and knowledgeably. This is to ensure you remain safe, from the start to the end.
