Metallic Expansion Joints
Expansion Joints are used in piping systems to absorb thermal expansion or terminal movement where the use of expansion loops is undesirable or impractical. Expansion joints are available in many different shapes and materials.
Metallic Expansion Joints
These types of Expansion Joints are completely sealed units assembled in numerous ways with different types of fittings as per specific requirements for various applications such as Axial, Universal, Gimbal, Hinged, Pressure Balance and others. We have the expertise to design and to suit the requirement.
We have an efficient engineering team with upgraded manufacturing and testing facilities to match the requirements of EJMA. These allow greater control of quality in every stage of production. The device containing one or more bellows is used to absorb dimensional changes such as those caused by thermal expansion or contraction of a pipe line or duct or vessels.
Non-Metallic Expansion Joints
Rubber Expansion Joints are a flexible connector fabricated from natural or synthetic elastomers and fabrics with metallic reinforcements designed to provide stress relief in piping systems due to thermal changes. When flexibility for this movement cannot be designed into the piping system itself, an expansion joint is the ideal solution. Rubber expansion joints compensate for lateral, torsional and angular movements preventing damage and undue downtime of plant operations.
The special construction of the rubber joints can solve problems like:
- Vibration, Noise, Shock, Corrosion and Abrasion
- Stresses, Load Stress and Equipment Movement
- Environmental Engineering
- Vibration, Pressure Pulsation and Movement in a Piping System
Fabric expansion Bellows: Non-metallic Expansion Bellows are flexible connectors designed to provide stress relief in ducting systems by absorbing movement caused by thermal changes particularly for low pressure applications. It also acts as a vibration isolator, shock absorbers and in some instances to make up for minor misalignment of adjoining with most of the metals. Hence fabric compensators can be an optimal solution.
