‘Advanced solutions for
flexibility in process piping
applications !

‘Fourwents’ Ball Joint Swivel Pipe Connector is engineered solutions for high-pressure applications, allowing movement in piping systems and connected equipment without compromising the seal or increasing mechanical stress. It incorporates a durable seal built to endure extreme temperatures and pressures, and it can be conveniently maintained via an injection port located on the connector’s casing. This connector is wellsuited for both static and dynamic applications, including steam systems, oil and gas, petrochemical plants, process industries, and marine operations. The ‘Fourwents’ Rota Ball Joint provides 360° continuous bidirectional rotation, while the Flexi Ball Joint offers the same full-range rotation along with an additional gimbal mechanism, enabling up to 30° of multi-directional pivot.

FOURWENT'S FLEXI BALL TYPE BALL JOINT APPLICATIONS

Ball joints can be used to absorb pipe movement in a variety of applications, including thermal expansion or contraction of pipe, tank, or building settlement, seismic movement, equipment movement such as solar panels and platens, and repetitive motion on bridges, oil platforms, and ships. The ability of ball joints to absorb motion is dependent on the OFF-SET Method, regardless of the source of the motion.
