Pig Traps

All industrial processes will leave residue inside pipe line walls. Overtime pipelines must be cleaned. Cleaning a pipeline means inserting a cleaning device, commonly known as a pig, at one end of the pipeline and allowing pipeline pressure to carry it to the other end of the pipeline. The pig travels through the pipe and scraping its sides to remove any buildup of unwanted material. Special tools and equipment are required to complete the pigging process.

There are different types of pig available for different cleaning application and “smart pigs” to monitor and record the integrity if the pipeline. Information gathered manually or from the “smart pig” is recorded and kept as historical data for future pigging jobs.

Each pigging job will have general as well as specific HSE considerations and requirements. All safety and environmental procedures must be followed when opening process lines.

Once a pigging job has been planned proper procedures must be followed by trained technicians in order to execute the pigging job. With the use of special tools and proper procedures the pigging job will usually be successful. Since operating the pig requires opening the process line there are specific safety issues that must be addressed.

This course is mainly targeted to process operators, process technologists laboratory and maintenance personnel. The course can also be applicable to employees working with equipment and materials purchasing, equipment procurement, job planning as well as immediate supervisors to the working technicians.
