THREADED BACKING FLANGES 8 HOLES

Threaded Flanges are used for special circumstances with their main advantage being that they can be attached to the pipe without welding. 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. PN = 1 bar pressure, PN16 – 16 Bar Pressure. DN = Size.
