Four Steps of Progressive Pigging
Mitigate unnecessary losses and maximize pipeline throughput.
TDW engineers its batching pigs to provide a highly reliable barrier between dissimilar products in the pipeline, such as jet fuel and gasoline, protecting pipeline owners and operators from the significant costs associated with product mixing and contamination.
Pigs equipped with proprietary RealSeal® discs and cups, for instance, have achieved a product contamination rate of less than 1 percent. A vast array of additional options is available as well. Examples include:
Batching pigs also make highly effective tools for filling lines with water and liquid displacement.
Best used for: all product types, including gas and liquids, and for all line types.
The UNISPHERE™ pig, a seamless, liquid-cast polyurethane ball, is designed for easy loading in an automated pig launcher for batching and displacement jobs. Gravity makes the automated launching and receiving of these spheres an easy process.
TDW manufactures foam pigs, including the REDSKIN™ line, with an oversized diameter. The resulting tight fit helps ensure an effective seal, regardless of a pipeline’s wall thickness, making it an extremely effective batching tool.
Whether pipeline operators want to install cups for highly effective batching or blades and brushes for cleaning, OptionAll™ pigs can be assembled into multiple configurations for a variety of applications.
The ULTRA™ pig, a mandrel-type pig, is designed for highly effective batching. This pig can be used with TDW RealSeal® urethane cups with multi-lip sealing grooves, which further enhances its sealing capabilities.
Pipeline owners and operators can use the X-Pig® utility tool for nearly any pigging function, including batching, cleaning, gauging and liquids displacement, which significantly adds to this pig’s overall value.
All-urethane VANTAGE®+ pigs, engineered with a two-cup configuration, provide excellent sealing capabilities for batching.
The BiDirectionAll Series III batching pig, available in diameters from 16 inches to 60 inches, can run in either direction within the pipeline if an application requires it.
The VANTAGE® V pig, featuring a steel mandrel body, has proven effective in batching, cleaning, and pipeline gauging — with little to no configuration modifications. Because the pig is designed to work with the same cups and discs as the OptionAll™ pig, it simplifies spare parts requirements.
