Types of Flanges

Flanges are used to connect pipes, valves, pumps, and other equipment in various industrial applications. There are several types of flanges available, including:

1. Weld Neck Flange: This type of flange is designed to be butt-welded to the pipe. It has a long tapered hub, which helps to reduce stress on the pipe and provides a smooth transition for the flow of fluid.
2. Slip-On Flange: This type of flange slides onto the pipe and is then welded in place. It is a popular type of flange because it is easy to install and is less expensive than some other types of flanges.
3. Socket Weld Flange: This type of flange is designed to be welded to the pipe using a socket weld connection. It is similar to a slip-on flange but has a socket at the bore to receive the pipe.
4. Blind Flange: This type of flange is used to seal off the end of a pipe or valve. It is typically used in applications where future expansion or maintenance may be required.
5. Threaded Flange: This type of flange has a threaded bore, which allows it to be screwed onto the pipe. It is commonly used in low-pressure applications and is easy to install and remove.
6. Lap Joint Flange: This type of flange is designed to be used with a stub end, which is a short piece of pipe that has a welded-on flange. The lap joint flange slides over the stub end and is then bolted in place.
7. Orifice Flange: This type of flange is used in applications where the flow of fluid needs to be measured or regulated. It has a special hole in the center that is designed to hold an orifice plate.

These are just a few of the most common types of flanges. There are many other specialized flanges available for specific applications, including high-pressure and high-temperature applications. It’s important to select the right type of flange for your specific needs to ensure a safe and reliable connection.
