The 6 Different Types of Flanges Available and Their Uses

Flange is the second most common method used for joining after welding. A flange is a collar or ring that is usually holed for accommodating bolts and welded or screwed at the end of a pipe. The tube or pipe enables objects to get attached. These kinds of pipes are widely used in construction zones, pipelines and plumbing. Flanges are also used when the joints need dismantling. The process also provides flexibility in maintenance of the different materials.  The best part is flanges can be used for any specific need in a project. There are various forged forged Flange Suppliers and forged flanges manufacturers in India.

So, whether you need to remove a flange or change it to accommodate a new pipe, you can do it all. Make sure you choose the right flange manufacturers in India. These pipes are more valuable as they reinforce pipes and also make them stronger than any other metal. So, in this blog, we discuss the different types of flanges available and their uses.

Slip-on Wedge Flanges:

Slip-on Flange has a hole which matches the outer diameter of the pipe, which makes it easy for the pipe to pass. Slip-on flange is placed on the pipe and the fillet is welded from both the sides. This type of flange is ideal for low pressure and temperature applications. The best part is these flanges are also available in large sizes, which helps in connecting to big bore pipes with storage tank nozzles. These flanges can also be forged for construction purposes.

Threaded Flanges:

The second type of flange available in the market is threaded flanges. Also known as screwed flange, threaded flanges have a thread inside the bore of the flange which easily fits into the pipe. This type of joint connection is simple, however, not very suitable for high pressure and temperature applications. Threaded flanges are mostly used for utility services.

Socket-Weld Flanges:

Socket weld flanges are mainly used for moderate services. These flanges were specially developed for small size high pressure piping. The static strength is equal to slip-on flanges. Fillet welding is generally done from outside the pipe. Generally, socket-weld flanges are used in small bore piping and suitable for low-pressure and temperature application.

Lap Joint Flanges:

A lap flange comprises of two components- a stub end and loose backing flange. Stud end is welded to the pipe whereas the back flange helps the pipe to move freely. The backing flange is made of different material than a stub. A back flange is normally made of carbon steel to save cost. Lap flange is ideal for applications that need frequent dismantling.

Weld Neck Flanges:

Weld neck flange is widely used in process piping. Weld neck has the highest level of joint integrity as compared to any other flange. This type of flange is ideal for high pressure and temperature application. However, these flanges are bulky and costly as compared to other types of flanges.

Blind Flanges:

Blind flange is a blank disk with a bolt hole. These flanges are used for another type of flange that isolates the piping system. Blind flanges are mainly used as a manhole cover in vessels.

Last Few Words:

Those were the six different types of flanges available in the market. These flanges can easily adapt to any specific type of project. These flanges are very valuable as these can reinforce pipes and make them stronger.
