Orifice Flanges

Benefits

• Integrated Diagnostics and Tapping Ports: Features pre-drilled, precision-tapped holes that allow direct connection of differential pressure transmitters without modifying the pipe walls.

• Streamlined System Maintenance: Equipped with dedicated jack-screws that allow operators to separate the flange face mechanically, enabling quick replacement of internal orifice plates during shutdowns.

• Exceptional Pressure Containment: Heavy-duty forged construction provides reliable joint sealing and structural stability under severe hydraulic pulsations and high line pressures.
  
  

  Applications

  Orifice flanges are widely deployed across heavy industries to manage continuous flow measurement and telemetry diagnostics in processing networks. In oil and gas refining operations, Carbon Steel orifice flange pairs are utilized within high-pressure hydrocarbon transport headers to measure crude oil and gas flow rates accurately under intense line pressures. Chemical processing plants leverage Stainless Steel and High Nickel Alloy orifice assemblies to monitor the transmission of aggressive chemical reagents, relying on the premium alloys to prevent rapid pitting and localized corrosion. For power generation facilities, specialized high-temperature Alloy Steel orifice flanges are integrated into superheated steam loops to facilitate continuous mass-flow calculations without suffering structural creep. Additionally, marine engineering platforms employ erosion-resistant Cupronickel orifice flanges in onboard desalination loops and seawater cooling mains to maintain absolute measurement precision despite continuous exposure to highly corrosive chloride environments.
