Petrotech Orifice Plate Assemblies are made to AGA/ASME recommendations and are reliable means to flow measurement. Assemblies to other international Standards viz. ISO, BS, DIN etc. are also available.Orifice flanges cover complete range of sizes pressure rating upto ASA 2500 of ANSI B16.36 as standard and dimensions as per other major international standard viz. – APL, MSS, BS and DIN etc. are also available on request. These flanges are available in various types such as Weld neck, Slip on, Screwed with facing FF, RJ, TG etc various types of tapping available are viz. Flange, Corner and D-D/2. Orifice Bore calculation can be carried out as per ASME MFC-3M, ASME 19.5 ISO 5167/BS1042, R.W. MILLER and L.K. Spink etc.Flange Assemblies are supplied ready to install in pipelines complete with Studs, Nuts, Jack Bolts, Gaskets and Drain Plugs. 

Petrotech Orifice Flanged Meter Run Assemblies are designed for use on many different process applications and accurate flow measurement.These devices are carefully designed and manufactured to achieve an optimum flow metering uncertainty, ensuring that installation of the orifice plate, adjacent pipe work and tapings are compliant with ISO 5167 and AGA.

The Daniel Senior Orifice Meter is a dual-chamber device that reigns as the most widely used means of measurement for natural gas. The Senior Orifice Fitting permits plate-changing under flowing conditions, which translates into no operation shutdown.Since its original development, the Senior Orifice Fitting product line has grown enormously to serve customers with applications for pipeline sizes from 2 inches to 48 inches, and pressure ratings up to 10,000 pounds per square inch. In addition, the use of corrosion resistant and other special materials makes this product suitable for sour gas service and other special applications. Daniel's most popular Senior Orifice Fitting, the "Flangnek®," has a weldneck inlet and a flanged outlet. Daniel fittings meet or exceed API Chapter 14, Section 3, Part 2 (14.3/AGA 3) requirements.Simplex Orifice Plate Holders:Daniel Simplex Orifice Plate Holders are single-chamber fittings that house and accurately position an orifice plate for differential pressure measurement. These fittings allow the removal or insertion of the orifice plate quickly and economically. The single chamber design allows for inspection and replacement of orifice plates without removing the Simplex meter from the flow line. Since Simplex fittings use one piece bodies, there is no spillage in liquid service, no rusted stud bolts, no nuts to remove, no flanges to spread apart and no line strain. The Simplex is designed and manufactured in strict accordance with all applicable ANSI, ASTM, API 14.3 and ISO 5167 specifications.
