Dispositif de confinement secondaire pour les applications de tuyauterie de pétrole brut Plan 66A
The SCB Secondary Containment Bushing is a standardized, dual-bushing arrangement intended for use in conjunction with API Plan 66A. It is used as the back-up to a primary seal and is usually incorporated into the cartridge. This seal is specifically targeted at crude-oil pipeline pump seals, such as the 8648VRS.
