A device and associated system for threading, cutting, and reaming pipe ends are described. The device and system utilizes a brushless DC electric motor. The devices also include on-board electronics and operator interface(s) to provide sophisticated control and information as to the various operations. Also described are methods of operating the devices and several different modes for performing various operations.

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.

A machine for cutting or beveling a pipe. A cutter unit rotates around the pipe while cutting any surface of the pipe after gripping and fixing the pipe. The machine includes: a main body which a pipe passes through the center portion thereof to be fixed; and a cutter unit coupled to the main body unit rotates around the fixed pipe to cut or bevel the pipe. The cutter unit may have a rotating unit on one side to pull the cutter unit aside and a locking unit on the other side to restrain or release the cutter unit. An entry control unit operating the cutter unit includes: a lever gear-engaged with an outer side surface of an entry control plate; and a clutch formed on a rotation shaft of the lever such that the restraint is released when the lever is lifted or pressed in the axial direction.

A device for preparing the end of a pipe includes a non-rotatable mandrel one end of which is attachable to the pipe. A motor rotates a sleeve around the mandrel and the sleeve retains an arm perpendicular to the mandrel for cutting the pipe. A cam surface on the rotating sleeve moves a cam follower. Movement of the cam follower is converted to rotational movement for turning a feed nut threaded on the mandrel. The rate at which the sleeve is advanced by the feed nut is controlled by limiting the movement of the cam follower.

A rotating machining device for machining a work piece includes a body having a support housing and a headstock rotatable relative to the support housing. A tool module is mounted to the headstock that includes a tool feed system and an actuating assembly is attached to the support housing. The actuating assembly is arranged to collide with and actuate the tool feed system at a collision point. The radial position of the collision point is adjustable relative to the tool module such that the collision point is repositionable independent of the tool module.

A rotating machining device for machining a work piece includes a support housing adapted for mounting on the work piece and a headstock rotatably mounted on the support housing about an axis. The headstock including an internal gear. A drive module is arranged to drive rotation of the headstock about the axis and at least one gear connection is formed between the internal gear and the drive module. The at least one gear connection is positioned radially inside of an outer diameter of the support housing to protect an operator from a pinch point associated with the at least one gear connection.

Pipe machining apparatuses are provided. In some aspects, a pipe machining apparatus may include a hinge to allow two sections of the pipe machining apparatus to move relative to one another. In another aspect, a support member may be provided to support a pipe machining apparatus on a surface. In a further aspect, a support member may be provided that allows lifting of a pipe machining apparatus in either a horizontal position or a vertical position.

An apparatus for cutting a pipe has a base comprising a pipe support having at least one set of lower rollers and an upper frame supporting a cutting apparatus and at least one upper roller. The upper frame is moveable relative to the base between an open position in which the pipe may be inserted between the at least one set of lower rollers and the at least one upper roller, and a clamping position in which the pipe is in contact with the at least one set of lower rollers and the at least one upper roller. The cutting apparatus comprises a grooving member configured to provide an annular groove on an outer surface of the pipe, a cutting member configured to cut the pipe, and a chamfering member configured to provide a chamfer on the outer surface of the pipe between a location of the annular groove and a location of the cut in the pipe.
