SENIOR, JUNIOR ORIFICE FITTING & PLATE

The Daniel Senior Orifice Fitting is a dual-chamber device that reigns as the most widely used means of measurement for natural gas. Designed to allow operation by one person, this differential technology meter saves time and money in many ways. The Senior Orifice Fitting permits plate-changing under flowing conditions, which translates into no operation shutdown. By maintaining flow during plate changes, the fitting also avoids the burden of bypass piping. In addition, the Senior Orifice Fitting is field-repairable. That means no downtime and other costs associated with shipping to a repair site. This fitting also offers special trims and an optional soft seat.
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.
