Project specific
How it works
Provides a highly durable, leak-proof, and corrosion-resistant conduit for transporting harsh chemical fumes and high-temperature exhaust from the process source to the abatement system.
- 01Custom fabrication
- 02Anti-corrosion coating (if required)
- 03On-site welding and assembly
- 04Leakage testing

- Corrosive chemical exhaust
- High-temperature flue gas
- Outdoor exposed ductwork
- Cleanroom extraction
- Proper expansion joints must be engineered for high-temperature runs.
- Weight of thick-walled ducts requires robust structural supports.
