Grooved Pipe Fittings

Flexible Coupling XGQT02

Grooved Flexible Coupling

Grooved Flexible Coupling allows for some movement at the joint. That is, Grooved Flexible Couplings are designed to transmit torque while allowing for some radial, axial and angular misalignment.  They can accommodate angular misalignments of up to a few degrees and some parallel misalignments.general purpose, mining, irrigation and compressed air where 5% or less deflection is required. Services include machinery and pipelines, process pipelines, mining and oilfield pipelines.

Flexible couplings are designed to transmit torque while permitting some radial, axial and angular misalignment. They can accommodate angular misalignment up to a few degrees and some parallel misalignment. The flexible couplings allow some angular misalignment and axial movement, which means that they can be used to create smooth bends and absorb thermal expansion a contraction in the piping system. In some cases, traditional expansion joints, loops, and other expansion devices may even be completely excluded from the system with the use of flexible couplings. When assembling stretched rubber gasket that is slightly smaller than the pipe diameter of the two pipe ends and creates the first seal. The coupling halves are then placed around the gasket which adapts to them. The coupling halves are bolted together to further improve the sealing. When the piping system is pressurized, a ”pressure reserve” is created due to the profile of the gasket. The sealing lips are pressed at the increasing pressure harder down against the gasket seating surface which creates the third seal and makes the connection completely leak-proof and airtight. The working temperature of the gaskets is -34°C to +110°C.
