Non-Metallic Expansion Joint
Non-Metallic Expansion Joint
Non-metallic expansion joints are flexible connectors designed to provide stress relief and seal in gaseous media in ducting systems.
They are fabricated from a wide variety of non-metallic materials, including synthetic elastomers, fabrics, insulation materials and fluoroplastics,
depending on the designs.

Expansion Joint Capabilities & Advantages |
Expansion joints provide flexibility in ductwork and are used to allow for 4 main situations: - expansion or contraction of the duct due to temperature changes. | |
Advantages of non-metallic expansion joints include | |
- Large movements in a short length |
◆ Single Layer Construction An expansion joint formed of one consolidated layer, often constructed from elastomers and reinforcement materials or fluoroplastics and reinforcement materials. |
◆ Multi-Layer Construction An expansion joint in which the various plies are of different materials which are not integrally bonded together
|
◆ Belt-Type Expansion Joint Configuration An expansion joint in which the flexible element is made like a flat belt
|
|
◆ Flanged-Type Expansion Joint Configuration An expansion joint in which the flexible element has flanges formed at right angles |
|
◆ Expansion Joint Clamping Configuration An expansion joint that utilizes both belt type and flanged configurations |
