摘要： Disclosed herein is a rotational roller apparatus for use with a pipeline unit. The pipeline unit is received in a pipeline for welding and/or inspection. The rotational roller is attached to and is able to support at least a portion of the weight of the pipeline unit. The rotational roller unit also includes an extension member and a reduced friction base. The reduced friction base is attached to an end of the extension member so that the rotational roller has a retracted and an extended configuration. In the extended configuration, the reduced friction base contacts an interior of the pipeline and supports at least a portion of the weight of the pipeline unit and thereby allows the unit to be rotated about a longitudinal axis within the pipeline.

摘要： A pipe expander assembly for replacing an existing pipe with a new pipe. The expander assembly has a slitter disposed about a wire rope and abutting an expander at a spherical joint. The expander comprises a cone to expand a slit pipe and is internally connected to the wire rope by jaws that expand and contract about the wire rope due to threading of a jam nut into the cone. A pipe puller is connected to the back of the expander at a clevis and is adapted for connection to a new pipe, either through a jaw system, an adaptor, or fusion to the pipe.

摘要： An internal caisson/jacket leg cutter and method provides a frame having upper and lower end portions. The upper end portion has rigging that enables the frame to be lifted. Extensible arms are movably supported upon the frame. The arms extend and retract along generally radially extending lines. Extension of the arms enables them to contact the inside surface of a caisson/jacket leg and thus center and anchor the frame within the caisson/jacket leg interior. A cutting mechanism at the lower end portion of the frame includes one or more rotary cutters or milling devices that cut the caisson/jacket leg wall as these cutters traverse an arc shaped path, tracking the caisson/jacket leg wall.

摘要： A tube cutting apparatus includes an inner blade (3), a drive shaft (1), a coupling shaft (2), a planetary gear (5), and a ring gear (6). The outer blade (4) has an inner peripheral surface which contacts an entire circumference of an outer periphery of a work W so as to cover a predetermined axial range of the outer periphery. The drive shaft (1) is rotatably supported inside the work W coaxially with the work W and defines a bore (11) therethrough at a position decentered by a predetermined amount within the drive shaft (1). The coupling shaft (2) is rotatably supported in the bore (11). The inner blade (3) is rotatably retained on an eccentric shaft (22) decentered at a front end portion of the coupling shaft (2) and is positioned inside the work W. The planetary gear (5) is positioned outside the work W and fitted on a rear end portion of the coupling shaft (2) coaxially and meshes with the ring gear (6). As the drive shaft (1) rotates, the inner blade (3) rotates while radially displacing the position of a portion of an outer periphery of the inner blade (3) which projects most outwardly in a radial direction of the work W.

摘要： The invention relates to a deburring tool for deburring abutting edges at orthogonally and obliquely extending transversal boreholes having a diameter of less than 10 mm in a component, such as an engine block, an injection system for combustion engines, a valve block and a camshaft or transmission shaft. The deburring tool is moved in a rotational and/or translatory manner and comprises a tool shaft (1), which is provided with a clamping end (2), and a tubular shaft part (5), characterized in that said tubular shaft part holds one or several cutting bodies (11) with a cutting blade (3), the cutting bodies being mounted in a movable manner in a passage (10), and in that a substance that is pressed under pressure into the through-bore (7) of the tool shaft (1) displaces the blade(s) to the exterior. The deburring tool is configured as a single piece and can be produced at low cost. Different blade geometries remove the burr by means of high speed deburring. The deburring tool can be introduced into the main borehole (HB) and the transversal borehole (QB). The technological requirements for the use of said deburring tool in intermittent assembly lines are therefore met.
