BRANCH CONNECTION WELD FLANGES

Branch connection weld flanges, also known as weld neck branch connection flanges, are a type of flange used in piping systems to create a branch connection to a pipeline. They are commonly used in high-pressure and high-temperature applications.

The branch connection flange is designed with a neck that is welded to the main pipeline, and a separate hub that forms the end of the branch. The hub is connected to the branch pipe with a fillet weld. This design allows for a strong and secure connection that can withstand high pressure and temperature.

The branch connection weld flanges can be of various types, including weldolets, sockolets, and threadolets, among others. Weldolets are branch connection weld flanges that are used for butt-welding to the main pipe. They have a socket that fits over the end of the pipe and a flat surface that is welded to the pipe. Sockolets are similar to weldolets but have a socket that is threaded instead of being flat, and the branch pipe is threaded to fit into it. Threadolets are similar to sockolets, but the branch pipe is threaded at both ends to fit into the threaded sockets of the main and branch pipes.

Branch connection weld flanges are commonly used in industries such as oil and gas, chemical processing, and petrochemicals, among others. They provide a reliable and leak-free connection between the main and branch pipes, and they are available in various materials, including carbon steel, stainless steel, and alloy steel. Overall, branch connection weld flanges are an essential component of many piping systems, providing a strong and reliable connection for branch piping.
