Rectangular Angle Flange Duct
Rectangular Angle Flange Duct
Rectangular Angle Flange Ducts are a prevalent choice in HVAC (Heating, Ventilation, and Air Conditioning) systems, offering a robust and efficient method for connecting rectangular duct sections. This flange system utilizes angle flanges—metal angles welded or bolted onto the duct ends—to create secure joints, ensuring airtight seals and structural integrity.
Angle Flanges: Typically made from mild steel, galvanized steel, or stainless steel, angle flanges are welded or bolted to the ends of rectangular ducts.
Standard Sizes: Angle flanges come in various sizes, commonly ranging from 3″ to 72″ in diameter.
- Material Options: Available materials include A36 steel, T304 stainless steel, and galvanized steel.
