	Pipeline inspection gauge - Wikipedia, the free encyclopedia
		Inline inspection pigs use various methods for inspecting the condition of a pipeline.
		Intelligent pigs, also called smart pigs, are used to inspect the pipeline with various sensors and record the data for later analysis.
		These pigs use technologies such as MFL (Magnetic Flux Leakage) and ultrasonics to detect the various aspects of the pipeline.

	GE Infrastructure - Pipelines and Pig FAQ
		After inspection with a magnetic inspection pig, the pipeline is usually left in a state of low level magnetization.
		Even in gas pipelines, the force of drag against the pipewall on a magnetic pig is usually higher than the weight of the pig, so the pig may speed up but does not run away down the riser.
		Pig traps are designed with a branch tee to divert the product flow to the side before the pig touches the end of the pig trap.

	About Pipeline Pigs
		Pipeline pigs are devices that are inserted into and travel throughout the length of a pipeline driven by a product flow.
		Gel Pigs, which are used in conjunction with conventional pigs to optimize pipeline dewatering, cleaning, and drying tasks.
		Gel pigs are a series of gelled liquid systems which have been developed for use in pipeline operations, either during initial commissioning, or as a part of a continuing maintenance program.

	Pipeline Pig Launching and Retrieving Procedures
		Pig launchers are used to launch the pig into the pipeline, and pig receivers are used to receive the pigs after they have made a successful run.
		Since company policies vary regarding whether the pig launcher is left on stream or isolated from the pipeline after the pig is launched, the operator should verify that the trap is isolated from the pipeline and depressurized before commencing any part of the launch procedure.
		Install the pig with the nose firmly in contact with the reducer between the barrel and the nominal bore section of the launcher.

	Dealing with a Stuck Pipeline Pig
		The goals of "pigging" a pipeline include not only running pigs to remove a product or to clean the line, but to do the work without sticking the pig.
		Getting the pig stuck rarely happens in a pipeline which is pigged routinely, but can happen when pigging a pipeline which has been neglected or never pigged before.
		Usually one of two conditions exist when a pig is stuck: fluid bypasses around the pig, or there is a complete blockage of the flow.

	Pipeline Cleaning Pigs, Pigging System, Polly, Foam, Steel, Urethane Pigs
		Pig Detectors are devices with indicator to detect a pig's passage in the pipeline.
		Pig Detectors are primarily located near launcher and/or receiver to confirm successful launching and receiving.
		Pig Trackers and Pingers consist of a signal-emitting transmitter and hand-held receiver.

		Pig: A device placed inside a pipeline that is used to clean or scrape residues from the inner wall of the pipe.
		A pig is pushed through the pipeline by the oil flowing in the pipeline.
		Pipeline operating data is remotely collected from transmitting devices located along the pipeline system.

		Pig cup/disc wear is a problem that effects all types of pigs, regardless of the application that they are used for.
		Wear is becoming of increased importance to the industry especially with the introduction of long distance pigging operations and the use of high differential pressure pigs for isolation purposes during sub-sea tie-ins.
		The pig is then modelled over the length of the pipeline, showing variation in characteristics such as differential pressure, leakage and film thickness as the pig seals wear.

	Pipeline Research Limited Specialist Pigging Concept for pig velocity control
		Control of pig velocity in low pressures gas pipelines is difficult, leading to inefficient pigging, potential loss of inspection data and possible dangers due to high accelerations.
		The higher, driving pressure behind the pig acts on the outside of the seals, pushing the oversized seal away from the pipewall.
		The less pressure required to initiate the pig the better as this is potential energy which is latterly converted to kinetic energy.

		When the pipeline route crosses certain sensitive areas, the wall thickness of pipe will be increased to provide additional protection of the area.
		Extensive steps will be taken to prevent a pipeline spill such as around-the-clock electronic monitoring of the pipelines for possible leaks, a protection system on the pipes to prevent corrosion and periodic internal inspection of the entire pipeline to ensure that there is no damage.
		No pipeline system component may be buried or submerged unless that component has the required external protective coating.

	Pipeline video inspection - Wikipedia, the free encyclopedia
		Pipeline video inspection is a form of telepresence used to visually inspect the interiors of pipelines.
		The PIG (pipeline inspection gauge) has sled-like runners, a body, and a head that may be swiveled.
		For larger pipes, rather than pulling the pig backward with the cable it may instead be mounted on a tracked carrier that pulls the trailing cable through the pipe.

	Polly Pig Pipeline Cleaning Pigs by Girard Industries
		The length of the pig is approximately twice its diameter to reduce the possibility of the pig tumbling in the pipeline.

	T.D. Williamson Newsletter - May 2002
		The life of a pig depends on such things as length, pig velocity, pig design, interior conditions and media in which the pig is running.
		Some pigs are designed to traverse bends with a radius of 1-1/2 D while others traverse a bend radius of 3 D or greater.
		Pig indicators also are used as switches to automatically shut down or start up compressor stations as the pig passes through.

	Pipeline Pigging Operations - ChE Forums
		For those not familliar with pipeline operations, pigging is the practice of inserting a device (the "pig") into a flowing pipeline that will run through the pipeline.
		The pig may be used to scrape off deposits (wax, parafins) from the inside of the pipeline, or to push liquids through a multi-phase pipeline.
		Basically the pig launcher and receivers are connected to the pipeline with bypass and isolation valves that allow fluid to either flow through or around the pig launcher/ receiver.

		For pipelines containing large quantities of debris BJ uses BJ Gel Pig technology as the most efficient and cost effective way to transport this debris out of the line.
		One of the main benefits of a gel train is that it allows us to clean pipelines in a single pass, providing we are able to accurately assess the amount of debris to be removed.
		On complex pipeline cleaning operations, for example where wax or asphaltenes have to be removed in conjunction with heavy inorganic deposits, gel cleaning may be combined with a solvent in one train.
