FAQS on 8 inch duct flange

Q: What materials are compatible with 8 inch duct flanges?

A: 8 inch duct flanges typically work with galvanized steel, stainless steel, or aluminum ductwork. They are designed to connect seamlessly with rubber duct expansion joints for vibration absorption. Material selection depends on temperature and corrosion requirements.

Q: How to install rubber duct expansion joints on an 8 inch duct flange?

A: Align the rubber duct expansion joint between two 8 inch duct flanges and secure with matching bolt patterns. Use gaskets to ensure airtight sealing. Avoid over-tightening to prevent deformation of the rubber joint.

Q: Can 4 inch exhaust flanges be adapted to 8 inch duct systems?

A: Yes, using a reducer flange or concentric adapter. Ensure proper sealing and mechanical support during conversion. This is common in hybrid systems connecting smaller exhaust components to larger ducts.

Q: What's the pressure rating for 8 inch duct flanges?

A: Standard 8 inch duct flanges typically handle 2-5 PSI in HVAC applications. Pressure capacity varies by material thickness and gasket quality. Confirm specifications with manufacturers for high-pressure systems.

Q: Do rubber duct expansion joints require maintenance with flange systems?

A: Inspect annually for cracks or hardening, especially near 8 inch flange connections. Replace if surface weathering exceeds manufacturer guidelines. Regular cleaning prevents debris accumulation in flange joints.
