Blind Flanges are solid discs used to seal the ends of piping systems, pressure vessel openings, or valves. They are the most stress-resistant flange type due to the bending moment from bolting and internal pressure, making them critical components in pipeline testing and maintenance.
Key Features:
• Effectively seals pipe ends and pressure vessel openings
• Highest resistance to bending stress among all flange types
• Ideal for pressure testing and system isolation
• Easy to remove for future pipeline access
