Alloy Steel and Carbon Steel Blind Flanges are solid flanges used to seal the end of piping systems, valves, or pressure vessel openings, providing complete isolation of flow.
These flanges have no bore and are designed to withstand internal pressure, making them essential for system shutdown, pressure testing, and future pipeline expansion.
Carbon steel blind flanges are widely used for general applications due to their cost-effectiveness, while alloy steel versions are suitable for high-pressure, high-temperature, and critical service conditions.
