What is pig device?
A “pig” in the pipeline industry is a tool that is sent down a pipeline and propelled by the pressure of the product flow in the pipeline itself. There are four main uses for pigs: Internal cleaning of pipelines. Inspection of the condition of pipeline walls (also known as an Inline Inspection (ILI) tool)
What is pig launching?
A pig launcher is a device which uses a pressurized container to shoot a cleaning device (“pig”) through the pipeline to perform a variety of functions including cleaning, monitoring, and maintaining of the pipe.
How many types of pigging are there?
There are four basic types of spheres: inflatable. Solid. Foam.
How do you start a pipeline pig?
Close the drain valve and slowly fill the trap by gradually opening the kicker valve, allowing venting through the vent valve. Once it is filled, close the vent valve and allow pressure to equalize across the isolation valve. Once you open the isolation valve, your pig is ready to be launched.

What is the use of pig launcher?
A pig launcher is a system used to send a PIG through a pipeline. It uses pressure to propel the PIG out of the launcher barrel and sends it through the pipeline system. These come in a variety of sizes depending on the pipeline size.
What does pig Stand For?
What is intelligent pigging?
Intelligent Pigging is an inspection technique whereby an inspection probe, often referred to as a “smart” pig, is propelled through a pipeline while gathering important data, such as the presence and location of corrosion or other irregularities on the inner walls of the pipe.
What is a pipeline pig trap?
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. This process is done without necessarily interfering with the flow of product in the pipe.
What is a smart pig pipeline?
Smart Pigs are inspection devices that record information about the internal conditions of a pipeline. They may measure several different things from inside of the pipeline, including restrictions and deformations of the pipe, as well as metal loss. Here a smart pig is being readied for insertion into the pipeline.
What kind of launcher does a pigging system use?
Most pigging systems use bidirectional launchers and receivers that can work in either direction. This is important to allow the PIG to be retrieved by the launcher if there is a blockage in the pipeline which prevents it from reaching the receiver.
Where is the pig indicator on a pig launcher?
The pig indicator on the launcher should not be installed on the launch barrel but downstream of the mainline bypass tee. The pig indicator on the receiver should be installed on the line size pipe near the reducer on the receiver barrel.
What kind of steel are pig launchers made out of?
These pig launchers were manufactured from carbon steel. They have a 16 major barrel, 12 minor barrel and measured 121 long. The pig launchers and receivers are used for cleaning piping systems. In addition, the pig launchers and receivers were designed for pressures of 512 PSIG at 100F.
How big of a barrel does a pig launcher need?
2) Size – A typical designation for pig launchers/receivers would be: This would indicate a launcher for a 10-inch pipeline with a 12-inch oversize barrel that allows the operator to slide the pig into launch position. The maximum operating pressure could be 740 psi.
