Types of Flanges

Businesses in a variety of industries rely on flanges to join pipes or components together or to keep equipment secured to a surface.

Different Types of Flanges

What is a Flange?

Before we discuss the various types of flanges on offer, it’s important to understand the purpose of a flange. A flange is a connecting piece of material that is designed to join together pipes and components or to secure equipment. You’ll find they are usually round or square in shape and are used in a huge number of applications and businesses. The flange face and the flange connection holes work together to create the flange. You will mount the flange face onto the surface and the flange connection holes are used to connect to another surface or to another flange. One of the most common applications for a variety of flange types is within pipe systems to support fluid sealing and pressure sealing. They may also be used within assembly lines to secure equipment in place and avoid incidents.

What are the Benefits of Flanges?

A flange is used to securely connect together valves, pumps, pipes and other pieces of equipment. Flanges all you to connect various components in a reliable manner, so that you don’t damage any part of the equipment or have other challenges during your work processes. As we start to discover the various types of flanges and ring type joints on offer, you’ll notice they are made from very durable and hardwearing materials. Most flange types offer high resistance to temperature, pressure and forces and can be used in a wide variety of processes. A flange works to seal joints together and prevent leaks with gases or liquids which could cause major issues for your business. It’s a useful tool to improve your business operations and offer protection for the environment.

One thing business owners are often surprised about when looking at the types of flange for the first time is just how easy they are to assemble and maintain. They are quick and easy to use and when you do need to make any type of repair to your equipment, you’ll find they can quickly be taken apart and put back together again. This helps to save time and offer good continuity for your business. All flange types come in a variety of different sizes, so you can find a suitable option for the materials and pipe diameters you are using. Pipe flanges and ring type joint gaskets are extremely versatile and are commonly used in the oil and gas industry, industrial plants, and water treatment plants.

Common Types of Flanges

The flange type that you need will depend on the work you are completing and many other factors that will help you decide on the design of the pipe flange and RTJs. A slip-on flange provides you with a large diameter flange that is then slipped over your pipes and welded into its place. These are one of the easiest types of flange to use for the first time and are best for low-pressure applications. Weld neck flanges have a long hub that is tapered and will be butt-welded to your pipe. It is very strong and resistant under pressure and can be used in both high temperature and pressure settings.

Threaded flanges include internal threads in their design that will allow them to be screwed to the pipe. If you need to assemble your connection on a regular basis and then pull it apart, this is a good option, but keep in mind they can’t be used with high pressure. Lap joint flanges have a backing flange to go with the flat face flange. Finally, blind flanges offer you a solid disc that will block the end of your piping system and are a great choice for inspection covers and applications where future maintenance might be required.

By choosing the right type of flange for your unique needs, you can ensure that you reduce the chances of incidents within your workplace. There are many different types of flange on offer today and that means you’ll have no trouble finding a solution for your company’s needs. Of course, we know choosing the right option can be overwhelming, which is why we are here to support you with that choice.
