Abstract:
A selectable angle pipe elbow comprising:two parts, each part having an inside and an outside surface and a proximal and a distal end,the first part comprising an arcuate segment having an outside cross-sectional dimension D and a constant axial radius of curvature R on its distal end, and means on the proximal end of the first part adapted to connect to a pipe or pipe fitting,the second part comprising an arcuate segment having a wall which has an inside cross-sectional dimension D and a constant axial radius of curvature R on its proximal end, means on the distal end of the second part adapted to connect to a pipe or pipe fitting, and an internal boss between the distal and the proximal ends of the second part, the boss having a first end proximal to the arcuate segment of the second part and a second end distal from the arcuate segment of the second part, the boss projecting inward from the inside surface from the wall, the outside cross-sectional dimension of the second part between the first and second ends of the boss being equal to the outside cross-sectional dimension of the arcuate segment of the second part.
