Imperial Bleed Rings are designed for installation within the bold circle of raised face flanges. One ½" fnpt tap is provided in each ring. Standard material is carbon steel but other materials are available on request. While primarily used to bleed gas or liquid from a line, they may also be manufactured with a full flange diameter for a substitute for orifice flanges. Prices for these units are available on request.
