Companion angle rings are installed on end connections when a smooth interior surface is required in a heavy duty application. These are most commonly installed on spiral pipe and fittings, or welded pipe and fittings. Often used in heavy duty dust collection, companion rings add rigidity and a rock solid connection to your ductwork. Standard angle rings are manufactured from mild steel but can be custom ordered in galvanized, aluminum, and stainless steel. Companion Rings may be installed in the factory or field via full weld, tack weld, or vanstone connection.
