Conical Cup Pigs
Conical cup type batching pigs are used for standard pigging operations such as filling and dewatering during hydrostatic testing, routine batching operations, and product removal. They are available in sizes from 2″ through 48″ with standard designs of 2-cup, 3-cup, and 4-cup. Conical cup pigs can also be equipped with brushes, blades, or gauging plates, allowing it to perform all the duties of batching, gauging, hydrostatic testing, product removal, pre-commissioning and on-stream cleaning.
The conical cup design allows for negotiation of varying internal pipe diameters and up to 15% reductions or deformations in nominal same size pipe. Conical cup pigs can be easily configured with discs in lieu of cups, or adding guide, sealing and spacer discs for additional sealing capabilities.
