ANSI B16.36 Stainless and Low Alloy Carbon Steel Precision Orifice Plates manufacturer in India, view ASME B16.36 Flange Dimensions and Standard
Similar to most flanges, the primary function of an orifice flange is to assist the worker in cleaning, modifying as well as inspecting a piping system. Yet, the ASME B16.36 Orifice Flange is used in combination with an orifice meter. This set up is useful while measuring the flow rate of media in the pipeline. The pipeline could have media that is either liquids or gas. There are pairs of pressure Tappings present on the orifice flange. These tappings are located mostly on 2 sides of the ANSI B16.36 Weld Neck Orifice Flange. They are directly opposite each other, and the tappings are machined into the component. Depending on the application it is to be used for, the manufacturer can produce any of the following facing types i.e., Raised Face Weld Neck Orifice Flanges, Ring-Type joint weld neck orifice flanges, Raised Face Slip-on Orifice Flange as well as Corner tap orifice flanges. In addition to measuring the flow of media in the pipeline, the Stainless Steel Orifice Flanges also is used to reduce its pressure. Furthermore, they also work well to restrict the flow of media.
Many Orifice Flange manufacturer provide a Weight Chart for the buyer’s reference, making it easier for them to select and purchase the correct component. ANSI B16.36 is a standard that includes aspects such as size, pressure rating, material, testing method, tolerances as well as Alloy Steel Orifice Flange Dimensions. Materials like stainless steel, Hastelloy, nickel alloys, Inconel, Monel, alloy steel as well as Carbon Steel Orifice Flanges ANSI B16.36 are common in the oil and gas industry.
