For Industrial and Institutional Corrosive Fume Exhaust and Drain Applications

REINFORCEMENT

Due to Harvel PVC Duct’s inherent rigidity, additional system reinforcements or flanges are not required for 6" through 24" sizes (.187" average wall or higher) up to 100°F and 10" of negative internal static pressure, provided proper support spacing requirements are followed. Reinforcements are not required for systems under positive pressure when standard support spacing requirements are followed.
