The term Vanstone flanged duct refers to a technique where flanges are placed onto the pipe, with the lip turned back at 90 degrees and left loose for a secure metal-to-metal connection when the flanges are pulled together and the Vanstone lips are connected. This allows for easy alignment of the centerline of the components.
