Stainless Steel Jack Screw Flange and Weld Neck Orifice Flange Manufacturer in India
These flanges are available in three types of faces - ring joint type, Corner tap orifice flanges, and Raised Face type. In this setting, the flange is fitted with an orifice meter by orifice flange manufacturers. The main purpose of including an orifice meter here is to check and measure the rate of the flow of a liquid or gas. Amongst all the flanges, it is perhaps the easiest to recognize them because they have a hole that is drilled through the face of the Jis Orifice Flange.
In this arrangement, the face of the flange remains perpendicular to the pipe. These flanges make use of additional bolts, which may be referred to as a jackscrew. Hence, many manufacturers and suppliers have labeled this type of component as an Ansi B 16.36 Jack Screw Flange. The orifice meter consists of three parts. One - the orifice plate, two - an orifice plate housing, and three - a meter tube, all of which collectively form a meter. Each part is responsible for governing some part of an operation. For instance, the A105 Precision Orifice Plates not only measure the rate of the flow but also aid in restricting the flow or reducing the pressure. Flanges are used as a means to determine the flow of materials, and so they are some of the most highly stressed parts in a piping system. Hence, various alloy grades may be used in the production of an Orifice Plate Flange. From stainless steel to carbon steel, or alloy steel, the grade used will depend on the operation it is to be used for. If an application requires high toughness and hardness with moderate tensile strength and no corrosion resistance properties, the Carbon Steel Orifice Weld Neck Flange will work well. However, if both good mechanical properties and varying levels of corrosion resistance properties are desired, it is recommended to use a corresponding grade of Stainless Steel Jack Screw Flange for said application.
