Rubber / Fabric Expansion Joints

Rubber Expansion Joints

Rubber expansion joints are flexible connectors made from elastomers, often reinforced with fabric or metal, designed to absorb movements and vibrations in piping systems. They are essential in many industrial applications for their ability to handle thermal expansion, reduce noise, and compensate for misalignment.

Fabric Expansion Joints

Fabric expansion joints are flexible connectors made from layers of heat-resistant fabrics and elastomers, designed to accommodate movements in duct systems. They are widely used in power plants, chemical plants, and other industries where high-temperature gases and movements need to be managed.

Rubber Expansion Joints

Axial Compression

Axial compression in bellows refers to the reduction in length of the bellows along its longitudinal axis when subjected to compressive forces.

Axial Extension

Axial extension in bellows refers to the increase in length of the bellows along its longitudinal axis when subjected to tensile forces.

Lateral Deflection

Lateral deflection in bellows refers to the sideways movement or displacement of the bellows perpendicular to its longitudinal axis when subjected to transverse forces.

Torsional Movement

Torsional movement in bellows refers to the rotational displacement around the longitudinal axis of the bellows, caused by applied twisting forces or torques.

Angular Moment

Angular movement in bellows is the change in angle between the two ends of the bellows when it bends around its center.

Vibration

Vibration in bellows refers to the oscillatory motion of the bellows due to periodic forces or disturbances.
