Deltaflow Solutions Private Limited

Product Overview:
Our IBR Approved Blind Flanges are high-performance solid flanges designed to close off the ends of piping systems securely. Manufactured to meet Indian Boiler Regulations (IBR) standards, these flanges are ideal for high-pressure and high-temperature applications, ensuring safe, leak-proof sealing in demanding environments.

Unlike standard flanges, blind flanges have no central bore, making them perfect for isolating sections of piping, performing maintenance, or pressure testing. They are precision-machined with bolt holes and sealing surfaces to match various industrial standards.
