What is pigging a water line?
In pipeline transportation, pigging is the practice of using pipeline inspection gauges or gadgets, devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline.
Why is it called a pipeline pig?
Early pigs were made from materials such as straw, barbed wire and leather and made a squealing sound while traveling through the pipes – for this reason, they were eventually called “pigs”. The name eventually became an acronym for “Pipeline Inspection Gauge” or “Pipeline Intervention Gauge”.
How does a pigging system work?
HOW PIGGING WORKS. In its simplest form, a pigging system consists of a solid projectile or plug (the ‘pig’) with a diameter slightly larger than the pipeline or tubing that is transporting the liquid. Pigging works by introducing this pig into the pipeline and pushing it through the pipe.
What is a plumbing pig?
Similar to cleaning your plumbing line, utility pigs are used to clean the pipeline of debris or seal the line. Debris can accumulate during construction, and the pipeline is pigged before production commences. Also, debris can build up on the pipeline, and the utility pig is used to scrape it away.
What is pigging and Decoking?
USA DeBusk offers pigging and decoking services for refining and chemical processing applications. This mechanical cleaning service removes fouling that accumulates on the inner walls of furnace coils, boilers and piping systems.
How much does a pipeline pig cost?
Defining a Smart Pig Pipeline A single pig can cost up to $1 million. PIGs have sensors and magnets for data transmission. In the past, they were known as pipeline inspection gadgets but are now pipeline integrity gauges. Smart pigs are part of that comprises of a pig launcher and pig receivers as well.
What is pig in pipeline pigging?
Pigging in the oil and gas industry is a form of flow assurance where pipeline pigs are used to purge, clean, and/or inspect pipelines to keep them running smoothly. Since the operation is hazardous, pigging must only be carried out by experienced professionals.
What is pig receiver?
A pig receiver is a device that “catches” the cleaning device (“pig”) after it has passed through the pipeline.
What is a pigging facility?
Facilities positioned within a pipeline network to launch and recover “pigs,” which are devices inserted into a pipeline to clean the inner walls of the pipe and monitor for critical conditions that could compromise pipeline integrity or operational efficiency, such as cracks, corrosion, or pipe deformations.
What is a pipeline pig receiver?
Pig Launchers and Receivers are pressure containing vessels or sections of piping within a pipeline system that are utilized for pipeline maintenance, cleaning, and inline inspection.
What is the purpose of pigging?
Pigging is an in-line inspection (ILI) technique in which devices referred to “pigs” are inserted into pipelines to perform cleaning and inspection activities. Pigging can be conducted on a variety of pipelines sizes without having to stop the flow of material through the line.
What is Caliper pigging?
Caliper pigs are used to measure pipeline internal geometry. They have an array of levers mounted on the body of the pig. The levers are connected to a recording device in the pig body.
