VSSJAFC (CC2F) Detachable Double Flange Dismantling Joint Overview
The Mingchao VSSJAFC (CC2F) is a detachable double-flange loose-sleeve force-transmission joint. Its extended removable assembly distinguishes it from the standard compact C2F configuration and supports project layouts that require a detachable pipeline or equipment interface.
Final selection depends on DN, face-to-face length, flange drilling, detachable geometry, maintenance clearance, installation envelope, operating conditions and the approved project drawing.
What Makes the CC2F Configuration Detachable
The CC2F uses an extended double-flange assembly with a distinct removable connection section. This architecture provides a detachable interface for project layouts where installation envelope and maintenance clearance must be considered.
The sleeve, follower, gasket and stud arrangement must be selected as one CC2F configuration. Final detachable geometry and clearance are controlled by the approved project drawing.
