Table Of Content
Slip on orifice flange are used with orifice flow meter that is why it is called orifice flanges. The purpose of orifice meter is to measure the flow rate of either liquids or gasses that pass through the pipe without losing its charm. Orifice flange blind are always used in a set of two. Orifice flanges are available in various classes from Class #300 to Class #2500. At DINESH INDUSTRIES, class #300 flanges are available in threaded, slip-on and weld neck end types whereas, class# 600 and above flanges are available in only weld neck type end connection. Weld neck orifice flange dimensions of these flanges are covered in ASME B16.36.
Orifice plate weld neck flange are widely used in conjunction with orifice meters for measuring the volumetric flow rate of liquids and gases through a pipe. Two weld neck orifice flanges are called an orifice flange union. Each carbon steel orifice flange comes with a pipe tap for measuring the pressure drop of the flow through an orifice plate.
Orifice flange class 150 are basically the same as standard weld neck, slip-on and screwed flanges except for the provision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack screws to facilitate separating the flanges for inspection.
In choosing the type of orifice flange class 300, the considerations affecting the choice of weld neck, slip-on and screwed standard flanges apply with equal force. They are made in pressure classes 300#, 600#, 900#, 1500# and 2500# in carbon steel, stainless steel and alloy materials and either in raised faced or ring joint.
Orifice flange weld neck are installed in a straight run of pipe in order to avoid turbulence at the plate. As a rule of thumb, an orifice flange has ten diameters of straight pipe upstream and five diameters of pipe downstream. There are guidelines set out in (American Gas Association) AGA Report #3 which is the Orifice Metering of Natural gas.
When installing the orifice flange slip on the pressure taps need to be at the same elevation to each other. Pressure taps should not be installed facing down as the taps could become plugged with debris in the line.
