PIGS COMPONENTS

Pigging Valves

An economical alternative to conventional launchers and receivers.  Available in sizes from 2" and above, it is capable of launching and receiving foam, steel, and solid-cast pigs in both cylindrical and spherical shapes.  They are designed for use as end-of line units or within closed loop systems.

Launchers and Receivers

Launchers and receivers are used to properly launch and receive pigs in the pipeline.  The basic design consists of an oversized barrel, a reducer to mate to existing pipe, and a closure door for access, as well as other connections for components.  Units are available for purchase or rental.

Closures

Closures allow access to a launcher, receiver or main pipeline.  They are used in lieu of a flange to blind-flange arrangement.  The two basic types are threaded and quick opening and are available in a wide range of sixes and pressure ratings.

Pig Detectors

Used to detect the passage of a pig.  the two basic categories are intrusive and non-intrusive.  An intrusive detector is permanently attached to the pipe and is equipped with a probe that intrudes into the pipeline.  The non-intrusive type does not intrude into the pipeline and is either magnetic, transmitter/ receiver, or ultrasonic.  Detectors can be equipped with electric signals to control the functioning of valves, pumps and compressors.

Pig Trackers and Pingers

Used to track pigs during pigging operations.  Operators are able to physically walk the line and pick up the signal emitted by the transmitter.  The difference between trackers and pingers is that transmitter are equipped with an on/ off switch and pingers are activated once they come in contact with a liquid.  Units can be purchased or rented.

Pig Tracking

Pig tracking can be performed on any pigging application from 2" to 48" pipelines with no limit to length or terrain.  Detailed reports are supplied after the job, with information such as pig speed and pressure charts that are key in pointing out possible problem areas in the pipeline.
