摘要： A pipe-tapered-thread machining tap has a thread, four spiral flutes and four cutting edges that include a plurality of thread intersection portions at each of which a corresponding one of the four cutting edges intersects with the thread. The thread intersection portions of the cutting edges have four groups, such that each of the four groups has ones of the thread intersection portions that are portions of a corresponding one of the four cutting edges. Every two of the thread intersection portions of each of the four groups is removed, such that, in each of the four groups, at least one of the thread intersection portions that is removed and at least another one of the thread intersection portions that is not removed are alternately arranged in a direction in which a corresponding one of the four cutting edges extends.

摘要： This invention is concerned with a work holder for a slotted tube to be deformed, preferably by moving the tube to a deforming work station and preventing the tube from rotating. The tube is fitted with an internal mandrel which is held in a fixed position by a vice. The mandrel has an upright blade that extends through the keyway of the slotted tube so that the tube can be slid along the mandrel relative to the deforming work station. In one method, continuous lengths of hollow pipes, tubes and the like can be threaded or otherwise externally deformed by supporting the workpiece internally with the mandrel. By changing the mandrel size, tubes of varying diameter can be accommodated. The deformed workpiece can be used in a variety of applications, one of which is a threaded hollow tube or stem member that has a cap welded to the rim of the tube to provide a pedestal cap of improved strength.

摘要： A refacing tool includes a feed assembly that holds a first set of cutters positioned for refacing the inner shoulder of a pin or box end of a tubular and a second set of cutters positioned for refacing the outer shoulder of the pin or box end. The axial spacing between the first set of cutters and the second set of cutters is fixed and determined by the geometry of the feed assembly. The refacing tool can simultaneously reface the inner shoulder and the outer shoulder, as well as chamfers.

摘要： A centering device on a cutting device using an ultrahigh pressure (UHP) hose carrying UHP fluid is designed to be inserted into a pipe or tube and cut the same from the inside out. In one example, the cutting device is for insertion into a wellbore for cutting the casing of the wellbore from within the wellbore with a revolvable UHP hose. The cutting head which effectuates the cut may be centered by the centering device that is generally conical in shape such that a portion of the centering device remains exterior to the pipe or tube as the UHP revolves during the cutting action.

摘要： A rotatable chuck for supporting a plastic coated workpiece in a power driven threading machine is disclosed comprising workpiece engaging jaws mounted on the machine spindle for rotation therewith and for pivotal movement relative thereto radially inwardly and outwardly of the spindle axis. Each jaw pivotally supports an insert holder provided with a pair of inserts for engaging the outer surface of the workpiece. Each of the insert holders pivotally supports a centering link associated with an adjacent jaw so as to be actuated in response to pivotal displacement of the jaws radially inwardly of the spindle axis to control the attitude of the insert holders so that the inserts are directed radially inwardly of the spindle axis to assure a uniform gripping action by the two inserts of each holder upon engagement with the workpiece. The centering links also displace the workpiece to a centered position coaxial with the spindle axis during inward displacement of the jaws.

摘要： A method of machining pipe at high speeds is disclosed that includes the steps of moving the pipe from a pipe rack onto a conveyor, moving the pipe longitudinally into the chuck of a threading machine or the like, clamping the pipe in the chuck, transferring the pipe from the conveyor to one or more steady rests, and supporting the steady rests on flexible wall air cylinders that will allow the steady rest to move as required to support the pipe which, because it is not straight, will whip and move laterally as it is rotated at the speeds required for high speed machining.
