Double studded adapter flanges are commonly utilized to connect and adapt flanges with different nominal sizes, pressure ratings, and configurations. We also produce and supply other types API 6A flanges, such as threaded flanges, spacer spool flanges, blind flanges, companion flanges, target flanges, test flanges, and adapter spools for all client needs
