Flanges are circular hubs that are used to connect two pipes together. They are also used to connect a pipe to a pressure vessel or a valve. There are several types of flanges, each with a different design and application. Here are some common types of flanges:


1. Weld Neck Flange(WN flange): Weld Neck Flange is a type of flange that is designed to be welded to the pipe. It has a tapered neck that connects to the pipe, which helps to distribute stress more evenly. This type of flange is commonly used in piping systems.


2. Slip-On Flange(SO flange): Slip-On Flange is a type of flange that can be slipped over the end of the pipe and secured in place with bolts. It is a simple and commonly used design.


3. Blind Flange(BL flange): Blind Flange is a type of flange that is used to close off a pipe or a vessel. It is a flat plate with holes for bolts and a center opening that matches the pipe size.


4. Socket Weld Flange(SW flange): A Socket Weld Flange is similar to a weld neck flange, but it also has a socket that the pipe slides into before being welded shut. This type of flange provides a very secure connection.


5. Threaded Flange (TH flange): A Threaded Flange is a type of flange that uses threads to connect the flange to the pipe. It is less common for piping systems but is sometimes used for smaller lines or in certain industrial applications.


6. Lap Joint Flange(LJ flange):A Lap Joint Flange is a specific type of flange designed to facilitate the creation of a lap joint in piping systems. In a lap joint, the ends of two pipes are overlapped and welded together, creating a strong connection. The flange provides the necessary support and sealing for the joint.


7. internal Flange (IF flange): IF Flange is a type of flange that is commonly used in industrial piping systems. It stands for "internal flange," which refers to a type of flange that is installed inside the pipe, rather than on the outside. This type of flange is typically used for connecting pipes of different diameters or for connecting a pipe to a pressure vessel or valve. It provides a secure and leak-proof connection, and can be used with various types of sealing materials and gaskets.


8. Plate Flange(PL flange): A Plate Flange is a type of flange that is a flat plate with holes for bolts. It is commonly used in piping systems for connecting two pipes together. When installing a Plate Flange, the pipe is inserted through the center of the flange and then secured with bolts. This type of flange is simple and cost-effective, and is commonly used in various industrial applications.
