In pipeline transportation, pigging is the practice of using devices known as pigs or scrapers to perform various maintenance operations.

This is done without stopping the flow of the product in the pipeline. A form of flow assurance for oil and gas pipelines and flowlines, pipeline pigging ensures the line is running smoothly. The maintenance tool, pipeline pigs are introduced into the line via a pig trap, which includes a launcher and receiver. Without interrupting flow, the pig is then forced through it by product flow,. Pipeline Pigging Products is a manufacturer of Internal Pipeline Cleaners referred to in the trade as “Poly Pigs.

Constructed of a flexible open cell polyurethane foam and various external wrappings, Poly Pigs have the ability to negotiate short radius bends, ells, tees, multi-dimensional piping and reduced port valves. Pipeline pigging is a concept in pipeline maintenance that involves the use of devices known as pigs, which clean pipelines and are capable of checking pipeline condition. All pipelines shall be suitable to pass pigs , even if pig traps are not permanently installed.

Pigging should be used for the pre-commissioning, commissioning and decommissioning of pipelines, cleaning and corrosion control (removal of wax, debris and stagnant liquids, batch inhibition),. Pigs may be used in hydrostatic testing and pipeline drying, internal cleaning,. The accuracy of location and measurement of anomalies by.

Pig launchers and receivers. Pigging facilities and considerations should be incorporated into. Flexible foam construction allows our pigs to negotiate short radius bends, reduced port valves and multi-dimensional pipe from below to over in diameter.

Pigs Unlimited International, Inc. We not only strive to meet the expectations of our customers, but exceed them. Canadian manufacturer of Urethane pipeline cleaners, known to the trade as Pipeline Pigs or Poly Pigs.

Pigs can maintain pipelines without disrupting the flow of fluids through them.

For existing operational pipelines pigging is normally performed without stopping the flow of the product in the pipeline. In natural-gas pipelines, pigs are used to manage liquid accumulation and keep the pipeline free. Pigs are used to empty the pipelines into the product tanks. The pigging process introduces this pig into the pipeline and pushes it through the pipe.

Inline Services offers pipeline pig parts which consist of cups,.

Sometimes it is introduced manually but more commonly automatically. After pigging , liquid is then collected or continues being processed.
