ABSTRACT:
A renewable wear-proof elbow is disclosed which can be connected to a pipe and become a part thereof for transporting particles of powdered material via compressed air. The renewable wear-proof elbow comprises a main elbow portion and a buffer chamber. The main elbow portion comprises: (a) an inlet at one end of the main elbow portion having a first flange for connection with a first section of the pipe; (b) an outlet at another end of the main elbow portion having a second flange for connection with a second section of the pipe; (c) a first side opening formed on a side wall of the main elbow portion opposite the inlet; and (d) a third flange formed around the first side opening. The buffer chamber has a second side opening, a central axis, and a fourth flange, which is formed around the second opening and is engageable with the third flange so as to allow the buffer chamber to be removably affixed to the main elbow portion at the first side opening thereof. The main elbow portion further comprises a bent pipe wall section near the first side opening thereof so as to allow the buffer chamber to be affixed to the main elbow portion in a manner such that the central axis of the buffer chamber is offset with respect to the central axis of the inlet.
