 The "STANDARD" FLANGE FLOW NOZZLE style is the most commonly used Flow Nozzle. It is designed to be inserted between pipe flanges. A special machined shoulder on the back side of the flange assures the proper alignment of the nozzle with the pipe I.D. This style Flow Nozzle utilizes pipe wall taps whose location is determined by the Beta Ratio.
 The "TAPPED" TYPE FLANGED FLOW NOZZLE is
similar to the "FLANGE" style,
but includes a downstream tap (usually a 1/2" connection) provided in the flange of the nozzle. This style nozzle is recommended in smaller line sizes where the downstream tap
may interfere with the pipe weld or downstream
mounting flange.
 The "WELD-IN" FLOW NOZZLE style is designed to be installed permanently in a pipe section. This nozzle has a specially machined step on its outside diameter that is used to align a beveled inlet and outlet bored pipe section. This type nozzle is widely used where high temperature and pressure applications prohibit the use of pipe flanges such as in power plant and feed water installations. Pipe wall taps are utilized with this style.
 The "HOLDING RING" FLOW NOZZLE style is designed so that the welding of dissimilar materials is eliminated, A special holding ring and locating pins are made of the same material as the pipe that the nozzle Is to be installed in. This allows for the nozzle to be offered in a wide range of materials. This style
is not recommended for line sizes below 4 Inches.
