Rubber expansion joints, also known as rubber bellows, are key players in a variety of applications, offering a crucial solution for managing movement, vibration, and misalignment in pipelines and ducting systems. Easyflex rubber expansion joints are designed to absorb movement in piping and ducting systems. They are the dynamic components that flex, stretch, and compress to compensate for the forces generated by thermal expansion, pressure fluctuations, and mechanical vibrations. These joints are made from high-quality rubber compounds, making them resilient, cost-effective, and highly versatile.

Rubber expansion joints offer several key advantages

• Flexibility: Their rubber construction allows them to handle various types of movement, including axial, lateral, and angular.
• Vibration Isolation: They effectively dampen vibrations, protecting the integrity of your system and reducing noise.
• Corrosion Resistance: Rubber expansion joints are highly resistant to corrosion, making them suitable for a wide range of environments, including chemical and industrial applications.
• Cost-Effectiveness: They provide an economical solution for managing movement in systems compared to rigid alternatives.
• Easy Installation: Rubber expansion joints are relatively simple to install and require minimal maintenance.

Construction

Rubber Expansion Joints are designed and manufactured in various polymers according to the need of the application and as per client specifications. If required, Easyflex can design according to any design code specified. The design and construction of the Rubber Expansion Joint is based on the application, flowing media and operating conditions – and also taking the following factors into consideration: chemical resistance of internal layers, weather, ozone and UV-resistance of external layers, temperature and pressure resistance and movement absorption capabilities.

Rubber Expansion joints are build up by an outer cover and an inner cover which is medium resistant and then reinforcement which is pressure resistant. Depending on the design data further accessories such as: vacuum supporting rings, inner sleeve, tie rods, gimbals etc. can be applied.
