Expansion joints

Expansion joints are vital components in most industrial plants. They are installed as flexible connections in air and flue gas pipe and duct systems to take up or compensate for thermal expansion, vibration and misalignments. Today, advancements in processing and generating technologies are being combined with high demands for efficiency. This, along with a clear orientation towards environmental protection, puts high demands on expansion joints design. When selecting the right expansion joint for the application, a number of important factors must be considered:

• Operating conditions
• Chemical or thermal resistance
• Pressure resistance, noise suppression
• Movements
