The Ball Flange Connector (BF) is a metal seal, ball-and-socket connector for bolting together misaligned pipe ends. The connector accommodates up to 10º of angular misalignment and can be rotated like a swivel-ring flange, enabling divers to make a quick and cost-effective connection. The Ball Flange Connector mates directly to a standard RTJ flange to provide a permanent, stress-free connection.
Ball Flange Connectors incorporate a metal-to-metal seal that can be tested and verified. Sealing integrity is maintained at any angle of misalignment, and the seal is unaffected by externally applied bending loads at all operating pressures. Wiper seals protect the metal seal area from contamination.
Ball Flange Connectors are available from stock in 4-inch through 24-inch, ANSI 900 rating. Thousands of these connectors have been installed worldwide, in sizes from 2-inch through 42-inch.

Flange Misalignment Connector is used for connection of subsea pipeline when the pipeline system is deflected. The internal ball component allows up to 10° angular adjustment along the pipe axis for easier alignment to flange face. 360° rotation of bolt holes can ensure the easy assembling and installation of flanges.
