About This Product
Blind Flanges
GS MetalFit supplies blind flanges designed to provide a secure closure for piping systems, valves, pressure vessels and other process equipment. Unlike flanges with a central bore, blind flanges are solid and are used where a piping section needs to be closed, isolated or prepared for future connection.
Our blind flange range is available in stainless steel, carbon steel, alloy steel, duplex and super duplex steel, nickel alloys and copper-nickel materials. Products can be supplied in different sizes, pressure classes, face configurations, material grades and dimensions according to specified project requirements.
Blind flanges are commonly used in piping systems where reliable pressure isolation and controlled access to the pipeline are required.
The range includes slip on, SORF and slip on plate flange configurations available in stainless steel, duplex, super duplex, carbon steel, alloy steel, nickel alloys and cupro nickel grades. Products can be supplied in different sizes, pressure classes, face types, materials and dimensions according to specified project requirements.
