The rubber expansion joints are a type of flexible connectors fabricated out of synthetic or natural elastomers. The manufacture of Rubber Expansion Joints in India designs them after keeping in mind the specifications. Some of the products have internal metallic reinforcements. This helps with stress relief in the piping systems. Eventually, it improves thermal movement and vibrations.
Based on the usage of rubber expansion joints, a wide array of material selections is done. These types of joints can undertake large movements over short distances. They assist with directional movement, be it angular, lateral, axial or torsional. It happens mostly due to external conditions. Besides, the rubber expansion joints reduce wind and shock loading and take control of seismic movement.
Areas of Application
You can use the rubber expansion joints for the following applications.
- Heating and cooling devices
- Desalination plants
- Cement industry
- Refineries
- Shipbuilding
- Steel mills
- Chemical industry
- Glass industry
- Materials handling technologies
- Water pipes
- Blower and fans
- Compressors
- Railed vehicles
- Pulp and paper industry
- Sugar industry
Advantage
The rubber expansion joints or spherical joints have a notable advantage over all other types. They are easy to use for corrosive applications. During installation, it maintains a sturdy structure without damage. Hence the joints come with a high life cycle.
The contour of this joint prevents sediment accumulation. It causes less turbulence and pressure drop as compared to the spool joints. It comes with a seal bead that eliminates the need for gaskets between the flanges. You can also install spheres on the flat face or raised face flanges.
Features of the Rubber Expansion Joints
- Temperature: Rubber joints made with standard material and construction can go up to a range 110°C. Some special types of joints can go up to 200 °C.
- Pressure: Depending on the diameter, rubber joints can withstand pressure up to 15 bar with a full vacuum rating.
- Movements: Rubber expansion joints allow smooth movement along the axial plane. It is during both compression and extension. However, the rubber joints can also absorb lateral movements with equal pressure.
- Spring Rates: Rubber joints display similar characteristics in the axial plane. This applies to standard face to face dimensions. Metal joints are stiff when subjected to lateral motion.
- Acoustical Impedance: Rubber joints reduce any undesirable transmission in the piping systems. It has an elastomeric composition that acts as a dampener. This way, it absorbs more perceptible noise and mechanical vibration.
Since you know all about rubber expansion joints, you can buy them from reputable manufacturers for an assured outcome.
