There are some hypotheses for why the process is called ‘pipeline pigging’, though none have been confirmed. One theory is that ‘pig’ stands for Pipeline Intervention Gadget. Another states that in the past, a leather-bound tool was sent through the pipeline, making the sound of a squealing pig as it passed through.
Another theory is that after opening a pig trap, the tool lies in a pile of mud, in the same way a pig does.
Regardless of the preferred hypotheses, ‘pipeline pigging’ or ‘pigs’ refers to several tools, usually propelled through the line, to perform a specific action inside the pipeline.
While build-up of foreign materials in a pipeline can cause a reduction in flow, it can also cause a rise in energy consumption due to high pressures, or even plug the pipeline. In the worst case it can cause cracks or flaws in the line with disastrous consequences, such as spills and the many associated dangers.
We will find or build the best pig for the job.
From the construction phase until abandonment, all pipelines require pigging at certain moments. The pigging experts at Intero Integrity Pipeline Services are specialists in selecting the best pig for the job. We choose only the best quality pigs from our suppliers, however for more challenging, critical jobs, we build our own pigs to the required specifications in order to guarantee the best possible service.
For pipelines without launchers and receivers, we also provide temporary installations, which will ensure a safe pipeline pigging process. The following pigs will pass through a pipeline at some stage during its life span.
