Expander Flange

If you are in the business of selling pipe and other industrial supplies, then you have probably heard of expander flanges. But what are they, and how can you use them to your advantage?

These specialized flanges are used to create a seal between two pipes. Expander flange is little-known but immensely useful equipment and they can be a lifesaver in certain situations.

In this post, we will take a closer look at expander flanges and explain how to use them. So read on to learn more!

1. What Is an Expander Flange

An expander flange is a specialized type of flange that is used to create a seal between two pipes. It is also sometimes called an expander spacer, and it gets its name from how it expands the pipe to create a tight seal.

The expander flange is a little-known but immensely useful tool that can be used in a variety of situations. It is particularly useful for connecting two pipes of different diameters, as it will expand the smaller pipe to match the diameter of the larger one.

This makes it an ideal tool for connecting pipes that have been damaged or are not a standard size. It can also be used to connect pipes that are at different angles, which can be helpful when trying to create a tight seal in difficult-to-reach places.

The expander flange is a simple but effective tool that can save you time and hassle when connecting pipes. If you need to connect two pipes of different sizes, or if the pipes are at an angle, do not hesitate to use an expander flange.

2. Expander Flange Applications

Expander flanges are often used in piping and tubing systems to compensate for thermal expansion and contraction. They can also be used as a seal or closure element for flange connection. Some of the most common expander flange applications include:

• Piping systems
• Tubing systems
• Steam traps
• Process control valves
• Pressure regulators
• Flow control valves
• Heat exchanger

3. Expander Flange Installation

Installation of expander flange can be very simple, but it is important to follow the manufacturer’s instructions closely. Here is how you install an expander flange.

Step #1 Clean the Sealing Surfaces

The first step is to clean the sealing surfaces on both the expander flange and the pipe or tubing. Be sure to remove all traces of dirt, grease, oil, and scale.

Step #2 Apply a Pipe Sealant

Next, apply a pipe sealant to the threads of the expander flange. This will help create a watertight seal when the expander flange is tightened down.

Step #3 Install the Expander Flange

Now it’s time to install the expander flange. Align the expander flange with the pipe or tubing and tighten it down using a wrench. Be sure to use a torque wrench to ensure that the expander flange is properly tightened.

Step #4 Test the Seal

Once the expander flange is installed, test the seal by applying pressure to the system. The expander flange should hold tight and not leak. If it does leak, reseal the joint and try again.

Now that you know how to use an expander flange, you can install it in your piping and tubing systems. It’s a great way to compensate for thermal expansion and contraction, and it can also be used as a seal or closure element.
