Orifice Flange

Stainless Steel Orifice Plate Flange Manufacturer, View Dimensions of ASME B16.36 Orifice Flanges

A flange is used to connect pipes, tubes, valves, together. They are available in various shapes, materials, and sizes. The material used to manufacture them also varies as per the end application. Orifice Flange is one such disc-shaped flange that is made with a ring type joint or a raised surface. Parts such as bolts, nuts, gaskets, jacking screws, plugs, and a pair of flange are used traditionally to assemble this flange. Stainless Steel Orifice Plate Flange provides easy maintenance and cleaning of these flanges. To measure the flow rate of liquids, and gases that flow through the pipe an orifice meter is used.

Carbon Steel Orifice Weld Neck Flange and Duplex Jack Screw Flange Supplier in India

Jis Precision Orifice Plates contain a small hole that is drilled in each flange. This helps in measuring the pressure built inside the pipe. The jackscrew helps in separating the 2 flanges while during the inspection and deep cleaning. Duplex Jack Screw Flange is used in wafer check valves, orifice plates, and spectacle blinds. They are used in paper, nuclear, steel, petrochemical, and power generation industries. Apart from this, they are also used in sewage treatment, oil production, and refineries. The main function of ASME B16.36 Orifice Flanges is to reduce the pressure and restrict the flow of the gases and materials inside the pipe.

The main purpose of this flange is to measure the rate of flow through the piping system. Carbon Steel Orifice Weld Neck Flange should be installed in horizontal pipes and should be at a considerable distance. When compared to welded joints, the flange joints are easy for inspection and easy to clean. However, there are chances that a flange joint may leak. One of the drawbacks of this is that more space is needed to connect 2 pipes with flanges and insulation of these flange pipes is said to be expensive.A182 Gr F316 Orifice Flange Unions do not require painting and blasting. A number of piping pools can be made without welding.

What Is An Weld Neck Orifice Flange?

An orifice flange is used to measure the flow of the fluid transfered by the pipeline via a flow nozzle positioned on the flange itself. orifice flange assembly consists of a pair of nuts, gaskets, flanges, bolts, orifice plate, jacking screws and plugs.
