Additional Info

Stainless steel raised face threaded flanges screw onto threaded pipe. One of the main advantages of using a threaded flange is that it can be installed and removed without welding. Threaded flanges aren't used with pipes with a thin wall thickness because of the threads needed to connect the pieces.
