ABSTRACT:
Pipe fittings are prepared for re-use by accurately re-beveling the pipe edges which are subsequently to be re-welded. A rotating table is provided with concentric rings which build up in height toward the center in order to accommodate the open end of various size fittings. A hand-crank is coupled to the rotary table to permit controlled rotation of a fitting being reconditioned. A vertically adjustable bracket is adapted to support a cutting torch directed at a predetermined angle, according to the bevel desired, proximate the upper end of the fitting. The table is then rotated with the crank through a full revolution in order to bevel the surface at which the torch is directed. As needed, the fitting may be inverted to refurbish a second end, and adapters may be provided to accommodate tees, elbows and the like.
