A flanged metallic exhaust hose, also often referred to as a flexible exhaust expansion joint, is a critical component designed to manage thermal expansion, vibration, and mechanical movement in high-temperature gas exhaust systems. Constructed from heat-resistant alloys such as stainless steel 321 or 310, it features a corrugated flexible body welded to sturdy flanges at both ends.

The flanged design allows for a robust, bolted connection that can withstand the high pressures and extreme temperatures encountered in exhaust applications. Its primary functions are to isolate vibration from engines, turbines, or generators; absorb the thermal expansion and contraction of rigid piping; and compensate for minor misalignments.

These components are essential in preventing stress damage to expensive equipment and rigid ductwork. They are widely used in power plants, marine engine exhausts, industrial furnaces, and HVAC systems, ensuring system integrity, safety, and longevity.
