The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

The invention relates to a deep hole drilling method for producing a pipe with an inner profile which has at least one recess extending helically along the inner side of the pipe, wherein with a deep hole drilling machine a tool, comprising a basic body extending along a longitudinal axis and at least one cutting edge arranged on an outer circumference of the basic body, is pulled or pushed through the interior of the pipe while being turned about its longitudinal axis, so that the cutting edge completes a cut along a helical cutting line on the inner side of the pipe.

A pipe end machining device configured to machine an end of a pipe includes an outer housing having a spindle rotatably mounted therein, tool carriers are mounted on the spindle, a hub assembly attached to the outer housing, a vertical adjustment assembly attached to the hub assembly and to the outer housing, and a drive assembly configured to rotate the spindle and tool carriers. The vertical adjustment assembly adjusts the upward and downward position of the cutting tools relative to the pipe. The hub assembly mounts the device to the pipe and fixes the relative upward or downward position of the cutting tools relative to the pipe, thereby preventing vibration and chatter when the device is cutting a planar surface on the end of the pipe.

A pipe lathe includes a shaft; a cutting head supported on the shaft for movement with the shaft; a mandrel positionable on an outboard end of the shaft for supporting the shaft along a machining axis; and a first external pipe clamp and a second external pipe clamp, the first and the second external pipe clamps supported for external pipe engagement substantially concentrically about the machining axis. Multiple spaced apart engagement sites provided by the mandrel within the pipe and the external pipe clamps on an outer surface of the pipe support the pipe in a linear and centered position for machining by the cutting head, even when the pipe is non-linear, flexible and possibly with a cross section that is on-circular.

Cutting tools for pipe cutting frames are disclosed. Example split frame pipe cutting tools include a frame and a slide tool configured to position a cutting edge in contact with the workpiece to performing cutting or boring on the workpiece, the slide tool comprising: a radial advancement mechanism configured to provide radial advancement of the cutting edge based on circumferential advancement of the slide tool by the frame; and an axial guide rail; a recirculating bearing carriage configured to slide in an axial direction along the axial guide rail and to couple the cutting edge to the axial guide rail; an axial advancement mechanism configured to advance the cutting edge in the axial direction with respect to the workpiece by translating radial advancement by the radial advancement mechanism to axial advancement based on a cutting template coupled to the radial advancement mechanism.

A cutting tool which includes a cutter operable to cut a hole defining a first diameter; and a drill bit mechanically coupled to the cutter, the drill bit operable to cut a hole defining a second diameter which can be smaller than the first diameter, the drill bit further includes a tool body having a recess and a detent member mechanically coupled to the tool body which can include a leg extending from the tool body and sized to be received within the recess upon one of deformation and movement of the leg, the leg biased in a radially outward direction by one of a wall of the recess and a biasing element of the tool.

A method of using a tool can include obtaining a tool which comprises a tool body having a recess and a detent member coupled to the tool body having a leg extending from the tool body, receiving the detent member of the tool body within the recess of the tool body upon one of deformation and movement of the leg by pushing the leg in a radially inward direction against a biasing of the leg in a radially outward direction with an edge of a hole formed in a portion of a pipe, passing the detent member through the hole formed in the pipe, catching the detent member in a removal direction, and moving a pipe coupon with the tool

A deburring tool includes a deburring head and a shaft portion connected to the deburring head. The deburring head includes a conical hollow body, a primary cutting edge and a secondary cutting edge both formed on the conical hollow body. The conical hollow body has at least one flute extending between interior and exterior conical surfaces of the conical hollow body, and at least one recessed cutout defined in the interior conical surface. The primary cutting edge is formed at a junction of a wall surface of the flute and a bottom surface of the recessed cutout. The secondary cutting edge is formed at a junction of a wall surface of the recessed cutout and the interior conical surface.

A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.

A pipe facing machine (PFM) system includes a PFM and a hydraulic power source having a single hydraulic pump arranged to provide a hydraulic oil flow to the PFM via single hydraulic circuit. The PFM includes a body defining an axis and a cutting head arranged to rotate and translate relative to the axis. Drive systems are arranged to drive clamping of the PFM on a workpiece, rotation of the cutting head about the axis, and translation of the cutting head along the axis. A hydraulic controller includes a plurality of control elements and hydraulically connects the drive systems. The hydraulic controller is arranged to direct and regulate hydraulic oil flow between the drive systems and the hydraulic controller based on signals from the control elements and a computer control system.
