We are a government approved largest Manufacturer, Supplier and Exporter of ASME 16.5 Blind Flanges / BLRF Flanges. Blind flanges is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. Blind Flanges are commonly used in petrochemical, pipe engineering, public services & water works. This flange is used to blank off pipelines, valves and pumps, it can also be used as an inspection cover. These are available in wide variety of sizes and applications. To make these products highly suitable for various industrial applications, we are offering them in customized designs.
