Threaded Flange: What You Need to Know

As a business owner, you know the importance of staying ahead of the competition. You also know that sometimes you have to make tweaks to your processes in order to do so. If you’re looking for a way to make your process more efficient, consider using threaded flanges.

Threaded flanges are a great way to join two pieces of metal together, and they’re very easy to use. In fact, you can probably use them without any help from an engineer or technician. Plus, they’re much more durable than traditional welds, which means they’ll last longer even under heavy stress.

In this article, we’ll take a closer look at threaded flanges and how they can benefit your business. If you’re interested in learning more about threaded flange standards, keep reading! We’ll explain what they are and how to use them.

1. Threaded Flange Definition and Its Uses

Threaded flanges are a type of flange that has a threaded hole in the center. This hole allows you to attach a bolt, which then holds the flange in place. Threaded flanges are usually used to join two pieces of metal together.

Threaded floor flange is very easy to use. In fact, you can probably use them without any help from an engineer or technician. Plus, they’re much more durable than traditional welds, which means they’ll last longer even under heavy stress.

Threaded flanges are often used in conjunction with threaded fittings. They provide a means of connecting two threaded pipe flanges, while also providing a seal that prevents leakage.

Additionally, threaded flanges can also be used to create a union between two threaded flange pipes, which allows for the easy removal of one of the pipes without having to disconnect the entire assembly.

Threaded flanges are great because they can be used for so many different purposes. Some threaded flange uses include:

  • joining two pieces of metal together
  • creating unions between threaded pipes
  • creating threaded flange joints that can be taken apart later without damaging the threaded flange itself.

The threaded flanges fabrication has been the most important need of today’s industries and it will remain so in future as well.

2. Parts & Construction of Threaded Flange

Several parts make up a threaded flange: the flange itself, the bolt, and the nut.


The flange is the part that attaches to the pipe flange or other piece of metal. The flange is usually made out of cast iron, steel threaded flange class, or stainless steel threaded flange. The flange has threaded holes and raised surfaces that correspond to where the nut and bolt will go.

The threaded flanges have a round metal edge with threaded bolt holes in the center. They’re designed to be attached to the end of a pipe or another material that needs to be connected to another part or section. The threaded hole allows you to screw in a bolt, which holds the threaded flange in place.

Nut Screw

The nut is externally threaded plate flanges as well, with a hexagonal portion at the bottom for tightening it onto the bolts. One side of this hexagon has been flattened off so you can easily tighten it onto your bolts without any issues.

The screwed flange part of the nut allows it to thread into your threaded flange. You also need a flat washer to prevent metal from seeping through the hole in the flat side of your nut screw. This keeps your threaded flange from leaking. 

3. The Manufacturing Process of a Threaded Flange

The manufacturing process for threaded flanges is very simple. Threaded flanges are already finished when they’re sent out to customers, which means you can get to work right away.

Below are the steps that threaded flanges go through during the manufacturing process:

Step #1 Mix the Materials

The materials used to make threaded hub flange are very simple. In fact, most threaded flanges only have three ingredients: cast iron, steel, and zinc. Sometimes you’ll see threaded flanges made out of copper or aluminum as well.

Step #2 Mold and Cool the Mixture

Once all of your material is mixed together, they’re set into a mold. This gives them their shape while they cool down.

Step #3 Clean the Flange

The final step in this process is to clean off your threaded flange so it’s ready for use. Machinery applies an electrochemical bath that cleans your flange without damaging the material.
