The Flue Gas Butterfly Damper features a compact circular single-disc design for fast flow control or shut-off in round ducts. Suitable for flue gas, hot air, and clean gas up to 400°C, it offers manual, electric, or pneumatic actuation and Class IV–VI sealing.

The Double Louver Bypass Damper is designed for boiler flue gas bypass systems. Double-layer blades and an air-sealed chamber minimize leakage through compressed-air purging. Ideal for SCR and air-preheater bypasses, it handles dusty gas up to 420°C.

The Guillotine Damper provides tight shut-off isolation for flue gas, hot air, and dust-laden gas pipelines. Its sliding knife plate achieves Class VI zero leakage, making it ideal for boiler maintenance. Manual, electric, pneumatic, or hydraulic drives are available for temperatures up to 550°C.

Fabric expansion joint is a kind of non-metallic expansion joint. It adopts multi-layer composite fabric membrane, which can absorb axial, lateral and angular displacement with no internal pressure thrust. It has good vibration and noise reduction performance, widely used in boiler flue, hot air and dust removal ducts. Custom shapes and high temperature resistant materials are available.

PTFE expansion joint is made of polytetrafluoroethylene bellows. It can absorb axial, lateral and angular displacement, damp vibration. It has excellent resistance to almost all strong acids, alkalis and organic solvents. Widely used in chemical corrosion pipelines, pharmaceutical and food clean systems. Custom sizes and anti-static PTFE are available.

Rectangular bellows expansion joint is specially designed for rectangular and square ducts. It can absorb axial, lateral and angular thermal displacement, reduce vibration and noise. Widely used in boiler flue gas, hot air and dust removal duct systems. Custom dimensions and various corrosion-resistant materials are available for high temperature and dusty gas conditions.
