Daniel Junior Single-Chamber Orifice Fitting

Daniel

Field-proven Daniel™ Junior™ Single-Chamber Orifice Fittings deliver reliable, predictable differential pressure flow measurement of gas and liquids in accordance with AGA 3, API 14.3 and OIML 5167 at high-volume metering stations and other sites requiring measurement on larger line sizes. The fitting's rack-and-pinion configuration saves users time and money by making plate inspections and changes safe, quick and simple. The plate can be safely removed from the fitting without spreading the flanges to eliminate the possibility of costly gas leakage or spillage of liquids, and all parts can be replaced onsite with no need to remove the fitting from the line to expedite maintenance and reduce downtime.

Features

  • Save time and money with rack-and-pinion design that simplifies plate inspections and change-outs
  • Replace parts as needed onsite with no need to remove the fitting from the line
  • Remove the plate without spreading the flanges to mitigate the possibility of costly gas leakage or liquid spillage
  • Eliminate damage with design that prevents fitting from being sealed until the carrier is fully seated and centered
  • Achieve a more secure seal between the orifice plate and body seat with the optional DSC plate sealing unit
  • Improve safety with manufacturing in accordance with ASTM and ANSI flange connection specifications
  • Ensure performance in accordance with ASME with optional hydrostatic testing to 1.5 times operating pressure
  • Choose corrosion-resistant and other optional casting materials for sour gas service and other harsh applications
