Orifice Flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. We ensure to test our range on well defined parameters at our own premises to deliver flawless products. They are used for all intensive purposes, similar to weld neck and slip-on flanges with extra machining.
These Flanges are used in various industrial applications and are available in various sizes and materials.
