ABSTRACT:
A pipe square apparatus and method for facing off the rough cut ends of a pipe. The pipe square apparatus comprising a planar reference surface; and alignment member for aligning the planar reference surface perpendicular to an axis of the pipe. An alternative embodiment of the pipe square apparatus includes an additional arrangement for pivoting the planar reference surface relative to the alignment member, the planar reference surface being locked in any one of a plurality of pivotal positions. The method for facing off the rough ends of the pipe includes cutting the pipe so that the pipe has an axial end; placing the pipe square apparatus on the pipe, the pipe square apparatus having a planar reference surface and alignment member for aligning the planar reference surface perpendicular to an axis of the pipe. The apparatus positioned so that the alignment member is parallel to the axis of the pipe and the planer reference surface abuts the axial end of the pipe. After the pipe square is in position, the person inspects the gaps and variations between the axial end of the pipe and the planer reference surface and then trims the axial end until there are no gaps.
