Info

Pigs are placed into lines by means of a launcher and a receiver, as shown in Figures 7-4a and b. They are moved down the line by means of pressure. Both the launcher and the receiver have bolted, swinging doors to install or remove the pigs. In the case of very large diameter pigs, a rail hoist is part of both units. Pigs are usually ~/8" larger than the inside diameter of the pipeline for a good tight fit. At intersections of pipelines, Scraper Bar Tees (Figure 2- 15) are used to keep the pig in line. The pig moves right through bends and turns until it reaches the receiver. Near the end of its trip and at checkpoints on the way, the pig passes over a device known as a "pig signal," and raises h i', ,, i L.~:/~ ~,.~ ~i-; ~ ---- .... ~--~. .-.: Figure ?-4A.

Pigs are tracked in lines by a radioactive isotope which gives off a radio signal and can be monitored from the air, ground, or a sat- ellite tracked by an electronic transmitter. The most common pig is the polyurethane style used for pigging lines up to 60 inches. These pigs are used for product or crude oil pipelines, chemical process piping, water systems, offshore condensate removal, and many other variations of pigging. 139
