Fire System Project High Quality DN25-350 Grooved Flexible Couplings

Grooved flexible coupling is a mechanical pipe joint that allows pipes of different diameters to be joined while providing a degree of flexibility. These couplings consist of two grooved end fittings and a flexible gasket or sleeve that is installed on the pipe. Grooves on the pipe ends provide a strong mechanical connection when the fitting is tightened.

Flexible coupling is also called clamp, open expansion joint, steel flexible pipe joint. It is a kind of pipe connection, reliable performance, easy to install products. At low pressure, by the elastic deformation of the sealing ring, to achieve the purpose of sealing; When the pressure increases, the medium acts on the sealing ring to play the role of self-sealing, and there is a gap between the pipe ends to compensate for the displacement and deflection of the pipe caused by thermal expansion and cold contraction.


This kind of coupling is specially desinged for the pipe bearing high pressure and mainly used in the application like mineral, electric plant, chemistry, etc. It joins roll or cut grooved pipe, grooved fittings, valves, and accessories. It provides a flexible pipe joint designed to accommodate a limited amount of linear and/or angular movement. 


HVAC (Heating, Ventilation, and Air Conditioning): Used to connect ducts in HVAC systems where flexibility may be required due to thermal expansion and contraction.

Fire Protection Systems: Typically used in fire sprinkler systems to connect pipes of different sizes while allowing for movement due to temperature changes.

Water and Wastewater Systems: For water and drainage systems where flexibility and ease of installation are important.

Industrial Piping: Used in industrial applications where grooved coupling systems are favored for their simplicity and speed of installation.


Flexible Couplings

Definition and Function:

Flexible couplings allow for some degree of misalignment between the connected shafts or pipes.

They can accommodate angular, parallel, or axial misalignment, providing more flexibility in installation and operation.

Misalignment:

Typically, flexible couplings can handle misalignment up to 5° in various directions (parallel, axial, or angular).

This feature reduces the need for precise alignment, simplifying installation and reducing maintenance costs.

Torque Transmission:

While they also transmit torque, some power loss may occur due to the flexibility inherent in the design.

Suitable for applications where slight misalignments are common or where vibration damping is required.

Applications:

Commonly used in environments where equipment misalignment, vibration, or frequent starts and stops are prevalent.

Examples include conveyor systems, fans, compressors, and automotive applications.
