Abstract:
An alignment device for assistance in bending a pipe having an end segment with a longitudinal axis at one or more pre-determined angles and in one or more pre-determined planes, the device comprising:a mounting section, said mounting section being securely attachable to the end segment, wherein a longitudinal axis of said mounting section defines a longitudinal guide axis of the device that is parallel to a longitudinal axis of the end segment, a gauge section rotatably coupled to and co-axial with said mounting section, said gauge section including a plumb arm pivotably suspended on a plumb mounting pin distal to said mounting section, wherein a longitudinal axis of said plumb arm defines a plumb axis and a longitudinal axis of said plumb mounting pin defines a plumb-mounting axis, and means to observe and determine angular movement of the pipe in a third plane so as to enable bending and measurement of the pipe at compound angles, wherein said longitudinal guide axis, said plumb axis and said plumb-mounting axis intersect one another and are orthogonal with respect to one another, thereby defining three degrees of rotation of the device to enable bending of the pipe at one or more angles in one or more bend planes.
