What is Orifice Flanges?

Understanding Orifice Flanges: A Comprehensive Guide

 
Orifice Flanges are a crucial component for fluid control and measurement system. They are essential in many industrial settings which allow precise control and measurement of flow. In this article, we will discuss the different types of orifice flanges, their classifications, specifications and applications, with a particular attention paid to the raised face flange and the related ideas.

What is an Orifice Flanges?

An orifice flange can be described as an especial type of flange that is designed to hold an orifice cylinder, which is utilized to gauge the rate of flow of gases and liquids in pipelines. Orifice plates are small, flat disc that has an opening in its center. It is placed between two orifices flanges to make a difference in pressure. The difference in pressure is helpful in determining the flow speed of the pipeline.

Types of Orifice Flanges

1. ASME B16.36 Orifice Flanges
These ASME B16.36 orifice Flanges have been designed in line with standards of the American Society of Mechanical Engineers (ASME) specifications. They ensure the compatibility and uniformity across different pipes systems. They're specifically designed to fit orifice plates, and offer accurate measurements.

2. Orifice Blind Flange
An orifice blind flange is designed to block off flow paths within a pipeline, where measurement is required. It functions as a barrier blocking the pipeline from flowing of the fluid. The flange type is vital for inspection and maintenance purposes.

3. Orifice Flange Types
There are a variety of kinds of orifice flanges that include:
Raised Face Flange with a protruding face which provides a seal face for the plate to ensure a perfect sealing and precise measurements.

Flat face Flange with flat surfaces that could be utilized in certain applications dependent on the seal requirements.

Key Standards and Codes

1. ASME Code for Orifice Flange
It is the ASME code for orifice flange defines the specifications and guidelines to manufacture orifice and flanges. They ensure that the flanges are made to industry standards and provide stability and reliability in measurement applications.

2. ASME Orifice Plate Standards
The ASME orifice plates standards define guidelines for the construction, design and assembly of orifice plate. The standards guarantee that orifice plates are compatible in conjunction with orifice flanges keeping accurate flow measurements.

Applications and Uses

1. Orifice Flange Use
Flanges for orifices are utilized in many industries like petroleum and gas as well as chemical processing and water treatment. They are crucial to monitor and control flow of liquids, and facilitating effective operation and maintenance of pipelines.

2. Orifice Plate and Flange
This orifice plate and flange combination is crucial to measuring flow. The orifice plate sits between two orifice flanges providing a controlled flow path that allows for a exact measurement of the velocity and flow.

Conclusion

Orifice flanges play an integral role of flow control and measurement systems. Knowing the various types of flanges, their standards and the applications of orifice flanges including the raised face flange will ensure that you will be able to select the appropriate component for your specific needs. When you follow ASME standards and codes you will be able to ensure precise and reliable performance of the pipeline system you have.
