Put some oil on the thread first, because the broken end is very short, so it can't be screwed with wrenches, pipe tongs and the like. You can use a sharp tool, such as a steel drill, a small steel drill or a hard steel nail, to knock the fracture counterclockwise with a hammer, and it will turn out a little at the same time. If you can't move, the vibration around you will be loose, and then you can come out counterclockwise. If the pipe is made of iron, it can be burned first and then beaten.
