Orifice Plates & Flange Unions

These orifice plates  and flange assemblies offered by us comes in complete range of sizes and pressure ratings standard and dimensions as per the major international standards. They are available in various types such as weld neck, slip on, etc. screwed with facing FF, RF, RTJ and TG. We offer various types of tapping in our orifice flange assemblies. These are supplied to our clients as ready to install in pipelines complete with studs, nuts, jack bolts, gaskets and drain plugs. Our range of orifice flange are manufactured in a broad variety of materials to ASTM standards like carbon steels, alloy steels and stainless steels.

The concentric square edge orifice plates we offer are most commonly used devices for flow measurement of clean liquids, gases and low velocity vapor flows. These plates have a sharp, square edged hole bored in a flat thin plate with or without bevel at the outlet depending on size & usage. They are widely used for restricting flows and dropping pressures.

These segmental orifice plates we offer are most useful where there are substantial entrained water or air and also if there are suspension in the fluids. This avoids build up in front of the orifice plate. The orifice hole is placed at the bottom for gas service and top for liquids.

These eccentric orifice plates we offer are most useful where there are substantial entrained water or air and also if there are suspension in the fluids. This avoids build up in front of the orifice plate. The orifice hole is placed at the bottom for gas service and top for liquids.

These conical entrance orifice plates are used for low Reynolds number (generally below 10,000) and give more constant or predictable discharge coefficient. At lower reynolds numbers, the discharge coefficient of square edge orifice plate may change by as much as 30%. These are more usable for viscous service.

These Quadrant Edge Orifice Plate are used for low reynolds number and give more constant discharge coefficient. At lower reynolds numbers, the discharge coefficient of square edge orifice plate may change by 30%.

Our Multi Stage Restriction Orifice Assembly have several orifice plates welded or assembled into one assembly for controlled stage wise pressure drop. The assembly comes with either butt weld or flanged ends.
