2" - 14" Brush cleaning pigs
(split-ring, hub-type brushes for 6" - 14" or wire-wheel brushes for 2" - 8" for cleaning debris and buildup)
Description:
Sturdy carbon-steel body equipped with easily replaceable cups or
discs, and circular brushes or brush components mounted on wear-compensating springs, providing 360o coverage of internal pipe surface. 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 pre-commission and on-stream cleaning of crude oil, refined product, and natural gas
pipelines where rust, millscale, sand, wax, organic growth, mud, oxides, and other foreign matter exist. Equipped with gauging plate, pig is used to prove roundness of pipe and to ensure excessive weld
penetration or debris does not exist. Also used to prove minimum bend radius prior to intelligent pig use.
Options:
Carbon steel, stainless steel, or aluminum body; cups manufactured from polyurethane, neoprene,
viton, epdm, buna-n or other elastomer compounds for special services; carbon-steel, stainless steel, prostran brushes or urethane blades; leaf or flat spring design; aluminum or steel gauging plate of
varying thickness, with or without slots; two-cup, three-cup or four-cup pig design; transmitter or pinger cavity; magnets; configurations can be modified to include discs for increased sealing
capabilities or bi-directional use on certain models; customized dimensions for special pigging applications.
