What is an stainless steel orifice flange and what is its purpose in piping systems?

A stainless steel orifice flange is used for flow measurement and control in piping systems. It has a unique configuration with a centered orifice plate that creates a pressure drop which allows precise flow measurement.

The flange helps regulate fluid flow, determine flow rates and calculate differential pressure. It is used in industries like oil & gas, chemical and water treatment.

Can an orifice plate flange be used for both liquid and gas flow measurements?

Yes, an orifice plate flange can be used for both liquid and gas flow measurements. The design and configuration along with appropriate calculations can help with it. However, proper selection of the plate design, size and specifications is required. They should be based on the properties of the fluid/gas being measured to ensure accurate and reliable results.

What is the purpose of the tapped holes or studs on an weld neck orifice flange?

The purpose of the tapped holes or studs on a weld neck orifice flange is to securely fasten the plate to it. The plate is positioned between the weld neck restriction orifice flange and the raised face. The holes or studs allow for precise alignment and attachment of the plate. This will ensure the plate remains in the correct position.

How does the choice of bolts material affect the pressure rating capacity of a ASME B16.36 orifice flange?

The choice of bolt material for an ASME B16.36 orifice flange can impact its pressure rating capacity. The bolts should possess sufficient strength and corrosion resistance to withstand the operating conditions and pressure requirements. The selection of appropriate bolt material should align with the desired pressure rating and ensure the integrity & reliability of the flange in a given application.
