Abstract: A pipe cutting apparatus has a rigid annular frame adapted to be coupled to a pipe to be cut. A cutting blade for cutting the pipe is removably associated with the annular frame. A mechanism is included to move the cutting blade with respect to the annular frame about an axis of revolution designed to coincide with a longitudinal axis of the pipe.

Abstract: A container for heating plates for butt welding pipes has one or more walls forming at least one receptacle for containing a heating plate; an insulation means surrounds the receptacle and is adapted to thermally insulate the receptacle from the surrounding environment.

Abstract: A pipe cutting apparatus has a substantially rigid annular frame adapted to be coupled to a pipe to be cut. Means for cutting the pipe is removably associated with the annular frame. A mechanism is included to move the cutting means with respect to the annular frame about an axis of revolution designed to substantially coincide with a longitudinal axis of the pipe.

Abstract: A chuck for gripping and moving cylindrical bodies, in particular fittings and pipe segments, including a main body defining an axis of rotation and a plurality of jaws fastened to the main body; the jaws are movable between a position of maximum closure, in which they are at the minimum distance from the axis of rotation, to a position of maximum opening, in which they are at the maximum distance from the axis of rotation; the chuck has an adjuster means for adjusting the positions of maximum closure and maximum opening and a movement means for moving the jaws between the positions of maximum closure and maximum opening; the chuck includes a fixing means adapted to allow the axial fixing of the chuck to a support member and the connection of the chuck to the support member so that they are angularly rotatable with respect to each other.

Abstract: A pipe processing apparatus, for forming branches on pipes made of thermoplastic material, including a base adapted to be fastened to the outer wall of a pipe and a supporting structure which extends from the base; a support member is slidingly associated with the supporting structure and is adapted to receive an interchangeable processing/handling means configured to interact with the pipe; the apparatus also includes a movement means which engages the support member in order to move it on command along a processing axis. The supporting structure includes a single elongated structural element.
