Intro
The world of piping and fittings can be complex and overwhelming, especially when it comes to selecting the right flange size for your project. Flanges are a crucial component in piping systems, as they provide a secure connection between pipes, valves, and other equipment. However, with so many different flange sizes and types available, it can be difficult to determine which one is right for your needs.
In this article, we will provide a comprehensive guide to flange sizes, including a printable chart that you can use as a reference. We will cover the different types of flanges, their sizes, and how to choose the right one for your project.
What is a Flange?
A flange is a type of piping component that is used to connect two pipes or a pipe to a valve or other equipment. Flanges are typically circular in shape and have a flat face with bolt holes. They are used to create a secure connection between two components, allowing for easy installation and maintenance.
Types of Flanges
There are several types of flanges available, each with its own unique characteristics and applications. Some of the most common types of flanges include:
- Slip-on flanges: These flanges are slipped over the end of a pipe and welded in place.
- Threaded flanges: These flanges have threads that allow them to be screwed onto the end of a pipe.
- Weld neck flanges: These flanges have a neck that is welded to the end of a pipe.
- Socket weld flanges: These flanges have a socket that is welded to the end of a pipe.

How to Choose the Right Flange Size
Choosing the right flange size can be a complex task, as there are many factors to consider. Here are some steps you can follow to ensure you choose the right flange size for your project:
- Determine the pipe size: The first step is to determine the size of the pipe you are working with. This will help you narrow down your options and choose a flange that is compatible with your pipe.
- Choose the flange type: Once you have determined the pipe size, you can choose the type of flange you need. Consider the application and the type of connection you need to make.
- Check the flange size chart: Use the flange size chart to determine the correct flange size for your pipe. Make sure to check the diameter, thickness, bolt circle, and bolt holes to ensure compatibility.
- Consider the pressure rating: Flanges have different pressure ratings, so make sure to choose a flange that can handle the pressure of your application.
