Batching, Gauging & Displacement Pigs

BGC-3
2" - 48" Batching pig with 3 cups
(used for evacuating air or liquid before and after hydrostatic testing and routine batching and displacement)

Description:
Sturdy carbon-steel body equipped with easily replaceable cups and discs.  Capable of being fitted with gauging plate machined to specifications.  2" through 14" are center-rod type and 16" through 48" are bolting pattern configuration.

Design Function:
Primarily used for evacuating air and liquid before and after hydrostatic testing, routine batching operations, and product removal.  Equipped with gauging plate, pig is used to prove roundness of pipe and to ensure excessive weld penetration or construction debris does not exist.  Also used to prove minimum bend radius prior to intelligent pig use.  With the addition of brushes or blades on the MDB model, this pig is able to perform all operations of pigging, including filling, dewatering, batching, cleaning, gauging, and product removal.

Options:
Carbon steel, stainless steel, or aluminum body; cups and discs manufactured from polyurethane, neoprene, viton, epdm, buna-n or other elastomer compounds for special services; aluminum or steel gauging plate of varying thickness, with or without slots; two-cup, three-cup, four-cup, two-disc and four-disc pig design; transmitter or pinger cavity; magnets; configurations can be modified to include cups and discs on single-pig configuration for increased sealing capabilities; customized dimensions for special pigging applications.
