Selecting the correct type of expansion joint is critical for system performance, safety, and long-term durability. The most common comparison in industrial applications is between fabric expansion joints and metal expansion joints.
Flexibility and Movement Absorption
Fabric expansion joints provide significantly higher flexibility compared to metal expansion joints. They can absorb axial, lateral, and angular movements simultaneously with very low reaction forces on connected equipment.
Temperature and Chemical Resistance
While metal expansion joints perform well under high pressure, fabric expansion joints offer superior resistance to corrosive gases and large temperature fluctuations. This makes them more suitable for flue gas and exhaust systems.
Maintenance and Service Life
- Fabric expansion joints: lower maintenance, lighter weight
- Metal expansion joints: higher stress on piping systems
Cost Efficiency
Fabric expansion joints are generally more cost-effective due to simpler installation, reduced structural loads, and longer service intervals.
Which One Should You Choose?
For applications involving high temperatures, vibration, and corrosive media, fabric expansion joints are often the preferred solution. Vanox, as an experienced fabric expansion joints manufacturer in Turkey, provides expert engineering support to help select the most suitable expansion joint type.
By understanding the differences between fabric and metal expansion joints, engineers can optimize system performance and reduce operational risks.
