Product Description

What are Grooved Flexible Couplings?

Grooved flexible couplings are mechanical connectors used to join pipes in a variety of systems, from plumbing and HVAC to fire protection and industrial applications. Unlike traditional rigid connections, these couplings incorporate a flexible element, typically made from synthetic rubber or elastomer, which allows for controlled movement and absorption of vibration, shock, and thermal expansion.

The design purpose of Flexible Couplings

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.

How Grooved Flexible couplings work?

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.

Advantages of Grooved Flexible Couplings

1. Versatility:One of the standout features of grooved flexible couplings is their adaptability to different pipe materials, including steel, stainless steel, ductile iron, and even PVC.

2. Easy Installation:Grooved flexible couplings are designed for swift and straightforward installation, reducing labor costs and project timelines.

3. Enhanced Durability:The flexibility of grooved couplings not only accommodates movement and misalignment but also mitigates stress on piping components, reducing the risk of leaks, fractures, and system failures.
