In addition to fabric expansion joints, U.S. Bellows is a major designer and fabricator of ducting. Design Integration is the design, manufacture, and shipping of expansion joints integrated into the ducting as a complete unit directly from U.S. Bellows. This enables U.S. Bellows to offer optimum system design and the lowest installed cost.

What does installed length refer to in a fabric expansion joint?
We can also do fabric expansion joints but that would be for a very low-pressure application.

What fabric is used in manufacturing expansion joints?
The fabric joints do not have stiffness values as the metallic bellows do.

The number of layers or plies is dependent upon the design conditions and we usually limit non-metallic expansion joints to two or three layers.
