Rectangular Expansion Joints

Rectangular Single Expansion Joints are custom-engineered metal bellows for large, rectangular duct systems (like in power plants, steel mills) to absorb thermal expansion, vibration, and minor movements (axial, lateral) in high-temp/pressure air/gas flows, featuring single bellows, specific corner designs (miter, camera), and often flow liners, designed to absorb movement while needing external anchors to handle pressure thrust.

Square and Rectangular Bellows: Any size with any shape and corner Rectangular Bellows especially used in low pressure ducting to absorb thermal expansion of duct and vibration from equipment. Rectangular Expansion Joint have a single, miter, camera and rounded corner design to absorb axial and lateral movement due to thermal expansion of system.
