The standard method for joining spiral duct sections is with male couplers. Verroloc jointing flanges may be used when easier removal of duct sections is required for maintenance or cleaning.
A flange joint includes two flange rings, attached to the duct ends with screws or rivets, and a closure ring fitted over both flanges. Gasket tape is placed between the flanges to ensure a proper seal.
The main benefit of these flanges is the ability to remove and replace duct sections easily, rather than simplifying installation. They are especially useful for large or high-level ducts. If ducts do not need to be removed periodically, male couplers are sufficient.
