What are Flanges?
Flanges are essential in piping systems, providing a secure and leak-tight connection between pipes and other equipment. They are used in various applications, from chemical and petrochemical to food and pharmaceutical industries.
Types of Flanges
There are several different flanges, each with unique features and benefits. Some of the most common flanges include slip-on flanges, weld neck flanges, Blind Flanges, threaded flanges, socket weld flanges, and lap joint flanges.
Slip-on Flanges are designed to be slipped over the end of a pipe and then welded in place. They are easy to install and are often used in low-pressure applications.
Weld neck flanges are similar to slip-on flanges but have a neck that extends from the flange body. This neck welds the flange to the pipe, providing additional strength and support. Weld neck flanges are often used in high-pressure and high-temperature applications.
Blind flanges seal off the end of a pipe or a pressure vessel. They have a solid disc that blocks fluid flow through the pipe or vessel.
Threaded flanges are designed to be threaded onto the end of a pipe, similar to a nut and bolt. They are often used in low-pressure applications where easy installation and removal are important.
Socket weld flanges are similar to slip-on flanges, but they have a socket used to weld the flange to the pipe. This provides a strong, leak-tight seal.
Lap Joint Flanges are used in along with lap joint stub ends. They have a radius at the base of the flange that allows them to be slipped over the stub end and then tightened into place using bolts. This provides a secure, leak-tight seal.
Conclusion
In summary, many different types of flanges are available, each with its unique features and benefits. By understanding the different types of flanges and their uses, you can make an informed decision about which type of flange is best suited for your specific application.
