A pipe cutting tool having: a plurality of rollers; a clamping member moveable between an open position in which a pipe is insertable between the plurality of rollers and a clamping position in which the pipe is secured between the rollers; a cutting apparatus having first, second, and third cutting members configured to optionally sequentially engage the pipe when positioned between the plurality of rollers; a drive motor drivingly connected to at least one of the rollers; and an actuator operatively connected to the drive motor.

Beveling tools having a variety of features are described. The tools can utilize a combination of handles, a protective external frame, guide rollers that are positionally adjusted by swing arms with timing lobes, or by an alternative guide bar mounting system, a helical knurled drive roller, guide rollers that have a convex or crowned face, skewed guide rollers, a positive clutch assembly for governing force applied to the guide rollers, a hand crank assembly for moving the tool when mounted on a workpiece, position adjustment provisions for varying the position of a milling head, and indicators providing visual feedback to an operator.

A bearing assembly includes a first race having an arcuate configuration and a first set of bearing elements. The first set of bearing elements is arranged to dynamically contact the first race and recirculate within the bearing assembly in a first direction. A second race has an arcuate configuration and is removably secured to the first race. A second set of bearing elements is arranged to dynamically contact the second race and recirculate within the bearing assembly in a second direction opposite the first direction.

A tube scraping apparatus comprises a body having a passageway for receiving a piping component; and a first blade and a second blade. The first blade and second blade each: are mounted to the body and shiftable between a first condition and a second condition; and having an engagement portion positioned to engage an outer diameter (OD) surface of the received piping component in at least one condition, the first blade engagement portion comprising a cutting edge for removing material from the OD surface. The second blade engagement portion comprises a partial thread for engaging the piping component to convert a rotation of the piping component relative to the body to an axial movement of the piping component relative to the body.

Pipe machining apparatuses, tool supports, and methods of operating pipe machining apparatuses are provided. In one aspect, a pipe machining apparatus includes a frame, a tool carrier coupled to and movable relative to the frame, and a tool support coupled to and movable with the tool carrier relative to the frame. The tool support is adapted to support a tool and move the tool in a first direction toward a pipe at a first increment and move the tool in a second direction away from the pipe at a second increment. The second increment is larger than the first increment.

An apparatus and method of using an apparatus for refacing a tubular connection is provided. In one example, the apparatus has a mandrel connectable to a threaded portion of a tubular connection and two face plates bearing cutters for refacing surfaces of the tubular connection. In this example, the cutting is controlled by an engaging nut moving along a threaded portion of a drive shaft, and the two face plates may be spaced apart at a fixed distance to maintain the distance between the torque-stop surface and the primary surface after refacing. Also, the apparatus uses a locking pin to assist in tightening or loosening the mandrel into place using the remainder of the apparatus. An air-oil system is provided to supply air and oil to the cutting surfaces as the apparatus refaces the shoulders of the connection. An exemplary pin refacer and an exemplary box refacer are both disclosed.

The invention relates to an anti-vibration plug for machining tubes and to a method for placing said plug inside a tube, wherein the plug comprises a central body (2) with arms (3) that open radially outwards intended to come into contact with the inside of the tube (1), a blocking screen (4) being arranged between the central body (2) and the arms (3), which blocks the inside of the tube (1) in the open position of the arms (3), whereas the central body (2) has an axial hole (5) wherein there is housed a piston (6) which movably acts on a peripheral part (8) which surrounds the central body (2) and generates the movement of the arms (3), the peripheral part (8) being subjected to a pushing force exerted by an elastic element (10) in the opposite direction to that in which the piston (6) pushes.

Disclosed is a chamfering machine which enables a smooth cutting operation by allowing a workpiece to be fixed to a position corresponding to an optimal cutting condition. The chamfering machine comprises a cutting position groove, which is formed in the bottom surface of an upper guide, and into which a part of the outer circumferential surface of a workpiece is inserted, wherein the central part of the cutting position groove is formed to correspond to the cutting end of a chamfering cutter. The machining method is configured such that the chamfering cutter enters perpendicular to a centerline direction of a circular material and, after entering while cutting, to a point where the cutting end of a cutting tip is in line with the centerline, rotates a tubular material or revolves the chamfering cutter around the tubular material and thus can cut the surface of the circular material.

In one aspect, a tool support for a pipe machining apparatus includes a support arm defining a groove therein and configured to support a tool, and a guide member at least partially positioned in the groove to allow movement of the support arm in a first direction and inhibit movement of the support arm in a second direction. In one aspect, a tool support includes a one-piece unitarily formed body member defining a cavity there through, and a tool support arm at least partially positioned in the cavity and configured to translate within the cavity. In one aspect, a tool support includes a first translating member configured to translate a tool toward and away from a pipe, and a second translating member configured to translate the tool toward and away from the pipe. The second translating member is coupled to and moveable relative to the first translating member.
