Types of Expansion Joints
1. Rubber Expansion Joints
Rubber expansion joints are used in suitable piping and equipment applications to accommodate movement and help isolate vibration. Their suitability depends on the elastomer, reinforcement, temperature, pressure, and fluid compatibility.
2. Metal Expansion Joints
Metal expansion joints, often manufactured with bellows, are designed for specified movement and operating conditions in piping, exhaust, and process systems.
3. Fabric Expansion Joints
Fabric expansion joints are commonly used in suitable ducting, ventilation, and flue-gas systems. Their construction is selected according to temperature, gas composition, pressure, and movement requirements.
