An Expansion Joint is a flexible seal. The flexible element is an engineered product designed to absorb thermal growth and movements in a piping or ducting system. The specific application frequently dictates the use of either a metal or fabric element.

The advantages of metal expansion joints:

• Can be designed for liquid or gaseous media

• Can withstand large temperature extremes, including cryogenic

• High pressure capability

• Non-Combustible

• Completely gas and liquid tight

• Two-ply testable capability

• Cost efficient for small piping systems when movement is minimal

• No maintenance

The advantages of fabric joints:

• Cost efficient for large ducting systems

• Large movement capabilities

• Lower initial design costs

• Ability to absorb torsion

• High corrosion resistance

• Vibration isolation

• Negligible spring force

• Accommodates large misalignments in ducting systems

• Easy replacement of just the fabric element

Applegate Industrial Materials offers a complete line of both
metal and fabric expansion joints in a wide range of shapes and styles to fit most any application.
