The TDW Foam Pig Line is an economical and effective pig for several applications. Their resilience enables them to negotiate short radius elbows, miter bends, and major diameter reductions. The Foam Pig Line is used for light cleaning, air removal prior to hydrostatic testing, water evacuation and drying. One version is bidirectional, which allows the pig to run in either direction.
The TDW Foam Pig Line is offered in five different configurations:
REDSKIN™ Swab Pig (RS-7)
REDSKIN™ Bristle Pig (RBR-7)
REDSKIN™ ROUGHRIDER® Pig (RRR-7)
REDSKIN™ Bidirectional Pig (RSBD-7)
WHITESKIN™ Pig (WS-2)
The WHITESKIN™ Pig is available in sizes 2” through 42” and is recommended for shorter runs for air or water service. Consult the factory for other WHITESKIN™ Pig applications.
Each REDSKIN™ pig is made from TDW’s tough, abrasion-resistant polyurethane foam with honeycomb surface texture, which effectively scrapes and wipes the pipeline wall. Wire brushes with bypass grooves provide full pipe coverage for effective cleaning and removal of hard deposits. The urethane cleaning wrap with bypass groove is effective for removing soft deposits such as paraffin. This increases the throughput, reduces pumping costs, and helps prevent corrosion. The oversized diameter ensures a tight fit and effective seal regardless of pipe wall thickness. The REDSKIN™ Pig is especially effective for line filling and dewatering associated with hydrostatic testing. The TDW Foam Pigs are packaged in plastic bags and shipped in cardboard boxes which extends shelf life in high-temperature, high-humidity regions.
