Precision Flow Control via Jack Screw Orifice Flange

Release time：2026-02-03    Click：20

　　In high-pressure piping systems requiring accurate flow measurement or restriction, the jack screw orifice flange provides a robust, accessible solution for installing and retrieving orifice plates without full line shutdown. Integrated with a pair of flanges and a set of radial jack screws, this assembly allows technicians to separate the flange faces just enough to slide the plate in or out—critical in oil & gas, power generation, and chemical processing plants.

　　The jack screw orifice flange eliminates the need for spool pieces or extensive disassembly. Typically forged from carbon or stainless steel to match pipeline specs, it complies with standards like ASME B16.36 and includes pressure taps for differential pressure transmitters. The jack screws—usually four evenly spaced—apply uniform force to prevent gasket damage and ensure resealing integrity after maintenance.

　　Unlike weld-in or carrier-style orifices, this design supports frequent calibration or fluid changeovers. Safety is enhanced by reducing hot work and confined-space entry. When combined with smart sensors, the jack screw orifice flange becomes part of a real-time monitoring ecosystem—proving that even century-old metering principles thrive with modern mechanical ingenuity.
