Poly Pigs and Steel Body Pigs , Pig Tracker
Foam pigs are an inexpensive and versatile type of pipeline cleaning device. They are used for drying, cleaning, batching, and product removal operations in the oil and gas, municipality, food and beverage, mining, chemical and petrochemical, cosmetic and pharmaceutical industries. Because they are lightweight and flexible, foam pigs are able to negotiate uncommon piping, fittings, and valves. Standard sizes range from 2" to 60", with industry-standard densities of foam ranging from 2-pound, 5-pound, and 8-pound per cubic foot. Common configurations include bare, criss-cross, wirebrush, plastic bristle, and silicon carbide. With various design options such as double-dish, double-nose, special coating patterns (single-spiral, turning pattern, totally coated, etc.), various lengths and diameters, pulling/handling ropes or cables, bypass jets, transmitter cavities.
Steel pigs are a more long-term, long-life pig. They consist of a steel mandrel body with easily replaceable sealing elements (cups and discs). Various brush types (spring-loaded, circular, wrap-around) can be utilized for removing deposits on the interior pipe wall. Standard configurations include cup, disc, multi-disc, conical and hybrid combination styles with various options such as adding or substituting a cup or disc, special lengths and diameters, gauging plates, articulated joints, transmitter cavities and magnet packs. The advantage of steel pigs is the ability to replace the wearing components (cups, discs, brushes, etc.), thereby rendering it a new pig.
Brush cleaning pigs are used during pre-commission and on-stream cleaning where rust, millscale, sand, wax, organic growth, mud, oxides, and other foreign matter exist. Sizes range from 2" through 48", with brush configurations including wire wheel, split-ring, wrap-around, and spring-loaded
Pig Trackers and Pingers consist of a signal-emitting transmitter and hand-held receiver with signal-pickup wand. The receivers utilize both audio and visual means to alert the operator of the pressence of the pig. The receivers allow the operator to make adjustments for signal strength as well as reducing outside interference. These are used to track the progress of a pig during a pig run, or can be used to locate a pig within a run of pipeline in land or water applications, above or below ground. Units are available for both purchase and rental.
