Threaded flange is screwing connected with NPT or BSP pipe thread, it is connected to other threaded piping components.

Threaded Flanges are used for special circumstances with their main advantage being that they can be attached to the pipe without welding(in low pressure, non-critical piping system) . Sometimes a seal weld is also used in conjunction with the threaded connection.A threaded flange or fitting is not suitable for a pipe system with thin wall thickness, because cutting thread on a pipe is not possible. Thus, thicker wall thickness must be chosen.
