About This Product
Orifice Flanges
GS MetalFit supplies orifice flanges designed for piping systems where a suitable flange arrangement is required for flow measurement using an orifice plate. These flanges provide the required connection points for installing and accessing an orifice plate and associated measurement components within the piping system.
Orifice flanges are commonly used in applications involving measurement of liquid, gas and other process fluids where controlled flow measurement is required. The flange arrangement can be supplied with suitable pressure classes, face configurations, sizes and material grades according to specified project requirements.
Our orifice flange range is available in stainless steel, carbon steel, alloy steel, duplex and super duplex steel, nickel alloys and copper-nickel materials.
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.
