Project Configuration
Mingchao can customize the product configuration based on the technical information, operating conditions and dimensional data you provide. Final configuration can be reviewed and manufactured to the approved project drawing.
VSSJAFG (CF) Single Flange Dismantling Joint Overview
The Mingchao VSSJAFG (CF) is a single-flange loose-sleeve force-transmission joint for pipeline installations requiring a flanged connection on one side and a project-specific pipe connection on the opposite side. The adjustable assembly supports installation and maintenance positioning, while the restrained fastener arrangement forms the required force-transmission configuration after final alignment.
Final selection depends on pipe outside diameter, face-to-face length, connection geometry, flange drilling, operating conditions and the approved project drawing.
How the CF Configuration Works
The CF assembly uses a flanged connection on one side and a project-specific pipe or interface arrangement on the opposite side. Its loose-sleeve geometry supports positioning during installation. After alignment, the restrained fastener arrangement establishes the required force-transmission configuration.
Final pipe outside diameter, connection geometry, flange drilling and installation envelope are controlled by the approved project drawing.
Materials & Construction
Material selection must be reviewed against the medium, operating conditions and approved project drawing.
