Blind Flanges
Blind flanges, also known as blanking flanges, are frequently employed in high-pressure applications. The terminal of a piping system is often sealed with a blind flange to stop the flow of liquids or gases. Once a piping system has been closed, blind flanges make it simple to access it. Our blind flanges come with female threads, raised or RTJ faces, or both. Blind flanges can be provided with or without a hub, depending on the needs of the customer. Companies in a variety of industries, including shipbuilding, power generation, petrochemical facilities, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants, and turnkey projects, can purchase blind plate flanges made at our facility.
