Rubber Expansion Joints by Easyflex , Design Selection and Fabrication
Introduction
A Rubber Expansion Joint is a flexible element fabricated of natural or synthetic elastomers, fabrics and reinforcements for this purpose.
They help to –
- Compensate for Thermal Expansion & Contraction
- Absorb movements, pressure & vibration
- Prevent damage to Equipment & Pipelines
- Extend lifespan of Piping Systems.
Flexible Connections
Piping systems experience thermal expansion & contraction caused by temperature variations and pressure generated by flowing mediums running through them. Without expansion joints, these thermal movements can lead to high-stress levels in the piping system, potentially resulting in leaks, cracks, or even complete system failure.
Expansion joints absorb these movements, thereby protecting the integrity of the pipes and ensuring the system operates efficiently under varying thermal conditions
For this reason, Rubber expansion joints are used in various systems including: HVAC (heating, air-conditioning and ventilation systems); Waste Water & Sewage Treatment Plants; Power Plants; Refineries and Petroleum industry; Chemical plants, Laboratories and Research facilities; Ship-Building and many other industries.
