Types of Flanges

Types of Flanges

A flange is usually a technique or method to connect pipes, channels, valves, and other kinds of equipment to form a piping system. It is a protruded lip, rim, or ridge whose shape is familiar to that of a disk. The flange is basically welded or screwed into channels, valves, etc., and, after that, it is joined with the help of a fastener. It provides simple access for identification, modification, and cleaning. Plus, it allows flexibility while maintaining the piping system because of its easy disassembly and enhanced access to the system components. A Flanges supplier in UAE is dedicated to providing high-quality and durable flanges for different purposes.

Flanges are commonly used by people in different countries for connecting different sections of pipe or for connecting pipes to different equipment. There are many suppliers of flanges in the world. The flanges suppliers in UAE are known for making high-quality forged steel rings or simply flanges.

Flanges, especially pipe flanges, are manufactured in different types of materials such as stainless steel, aluminum, cast iron, brass, bronze, plastic, etc. However, the most used material is forged carbon steel, which is the reason they work for a long time and further give immaculate wrap-up. Also, the material of a flange is chosen as per the material of the pipe. The pipe and the flange are both made of the same material.

Different Types Of Flanges

There are various types of flanges available in the market and utilized for various purposes. Below, we have listed some of the common flange types available.

Threaded Flanges

Also referred to as the screwed flange, it features thread within the flange hole, which easily positions with the matching male thread present on the hose. Simply check the threading on the hose you want to connect to. The main advantage of this flange is that it can be connected without the need for welding. Also, it is simple to attach and remove.

Socket-weld Flanges

This type of flange is considered suitable for smaller diameter pipes in low-pressure and low-temperature scenarios. It has a connection to position the pipe into the flange and then simply fix the link with a sole multi-pass fillet weld. This makes this flange straightforward to install than any other welded flanges.

Slip-on Flanges

These flanges are available in a variety of sizes to fit with different systems with high flow rates and performance. It is overused in numerous fluid pipelines. Basically, check the flange size with the external broadness of the pipe you wish to connect. The installation can be slightly tricky as you will be required to weld each side to properly secure the flange with the pipe. Moreover, slip-on flanges are thinner than other flanges, stronger, reliable, and cost-efficient.

Slip-on Flanges

Lap joint Flanges

Having a two-piece style, this flange is generally utilized with a Taft or stub end that is tail-welded to the pipe with another flange loose behind it – lap joint. These are used in structures with limited space that need cleaning frequently.  Plus, because they are simply assembled and aligned, they are used in low-pressure applications. They look very familiar to slip-on flanges, with the only difference being the rounded interior edge of the face of the flange.

Weld-neck Flanges

Similar to lap-flanges, the weld-neck flanges need butt welding for fitting. However, they are considered a good option for process piping because of their integrity and capability to employ them in high-temperature as well as high-pressure systems. They are typically joined to the neck of the pipe. Plus, they are wielded in such a manner that their thickness is identical to the measurements of the pipe the flanges are used with.

Weld-neck Flanges

Blind Flanges

Basically, utilized for separating or terminating piping systems, these flanges are boltable empty disks. When installed appropriately and integrated with the right gaskets, they offer a strong seal that is effortless to uninstall. They are further used to protect the end of the piping system and stop the flow.

Blind Flanges

Spectacle Blind Flanges

They are used for simply connecting pipes to each other or for permanently splitting pipe systems. A spectacle blind is simply a steel plate that is cut into two discs of specific thickness. These two discs are then connected to each other by a steel part. One of the discs is a strong plate, whereas the other is a ring that has a flange inner diameter.

Specialty Flanges

The flanges which have been discussed above are some of the common types. Still, there is a wide variety of extra specialized flanges available out there to match a variety of uses. These include expanding flanges, nipo flanges, orifice, reducing flanges, and long weld neck flanges.

Faces Of Flanges

Flange type is not the only thing that you need to consider while selecting the perfect flange for the piping structures. The face type of the flange is another factor you need to check as it will have a profound impact on the end result. Some of the common face types are as follows.

Flat Face (FF)

Just like its name, this flange features an even, flat surface which is integrated with a full-face liner that touches most of the surface of the flange.

Raised Face (RF)

This flange comes with a small elevated section around the flange hole with an interior hole circle gasket.

Ring Joint Face (RTJ)

It is employed in high-temperature and high-pressure processes; this also has a groove that features the metal gasket to sustain the seal.

Tongue and Groove (T&G)

This kind of flange comes with similar grooves and elevated sections. It helps in installation as the style helps to keep the flanges self-align.

Male and Female (M&F)

They also employ a similar set of grooves and elevated sections to protect the gasket. But, unlike T&G flanges, they reserve the gasket on the female side to provide precise placement and more material gasket options.

On the whole, flanges offer a reliable way to form a piping system by connecting pipes, valves, pumps easily and securely. But this will only be possible if you invest in a top-notch quality flange.
