The UFDPSE solid-cast pig is a brand new design that was developed by Pigs Unlimited. The pig is constructed of high-grade abrasion and chemical resistant solid-cast polyurethane material. It is capable of negotiating tight-radius bends as well as varying internal diameters of nominal pipe. What sets this pig apart from others on the market is the square edge design of the discs. We have combined the cleaning power of a square edge disc with the flexibility and functionality of a solid-cast pig. The multiple sealing surfaces provide an optimal seal and the square edge design provides reliable cleaning performance. Primarily used for product removal, batching, hydrostatic testing, and paraffin, debris or other buildup removal. Because they are lighter in weight than steel-mandrel pigs, this allows for longer and more efficient runs. Options include varying durometers (hardness), transmitter or pinger cavity, and magnets.
