摘要： A rod pushing and pulling machine includes at least one hydraulic cylinder having a front end thereof engagable with a reaction surface at an entry opening of an existing pipeline or borehole, a spindle assembly, and a dual vise assembly. The spindle assembly includes a frame, a spindle shaft rotatably mounted in the frame, a distal end of the spindle shaft being threaded for engagement with a mating thread of a rod, a drive system for rotating the spindle shaft in threading and unthreading directions, the spindle frame being secured to a rear end of the hydraulic cylinder for pushing or pulling of a rod string engaged to the spindle shaft upon extension or retraction of the hydraulic cylinder, and a support assembly for the spindle shaft. The support assembly includes a set of roller bearings rotatably supporting the spindle shaft, a radial flange on the spindle shaft, and a load flange secured to the spindle frame positioned to engage the radial flange, whereby the radial flange comes into engagement with the load flange during pulling operation to prevent rotation of the spindle shaft during pulling operation, and leaves engagement with the load flange during pushing operation so that the spindle shaft may rotate during pushing operation supported by the roller bearings. The dual vise assembly has two pairs of separately actuable jaws positioned to grip a rod nearest the spindle shaft and a rod adjacent the rod nearest the spindle shaft.

摘要： A mount for traveling within a pipe to center a tool, such as a camera, within the pipe. Inner and outer concentric cylinders are slidably nested. Pivoted leg pairs have one end connected to the outer cylinder and another end connected to the inner cylinder. The pivoted leg pairs move radially inward or outward as the inner and outer cylinder move axially with respect to each other. A spring biases wheels attached to the distal end of the pivoted leg pairs radially outward. The mount centers the inner and outer cylinder within the pipe and automatically adjusts to different diameters of pipes. The mount overcomes obstructions within the pipe and is easily retrievable. The interior of the pipe may be inspected or worked upon.

摘要： A puller is provided with a number of advantages. Pullers are described that have a high power to weight ratio, and a high power to volume ratio. Examples of pullers and pulling systems include harmonic drive gear reduction elements and configurations that provide high cable friction in a small device volume. Examples of pullers and pulling systems also include constant force pulling which is desirable in particular for small diameter pipe replacement. Using pullers and pulling systems as described, minimally invasive pipe replacement operations are possible. Reversible pullers are also provided that decrease the amount of time needed to burst or split multiple segments of pipe.

摘要： The present disclosure relates to a method for repairing a partially collapsed pipe. The method comprises fitting a mesh stent around the outside of an actuation assembly of a pipe repair apparatus, and positioning the pipe repair apparatus within a portion of the pipe, at least a part of the portion of the pipe being partially collapsed. The method also comprises causing actuation between a retracted configuration and an extended configuration such that the partially collapsed part of the pipe changes from a partially collapsed form towards a non-collapsed form. The method also comprises removing the pipe repair apparatus from the pipe and leaving the mesh stent in the portion of the pipe.

摘要： An in-line inspection (ILI) tool 20 for use inspecting pipelines includes a plurality of collapsible guide centralizers 100 configured and sized to correspond to the inside diameter of the pipeline being inspected. The guide centralizes 100 include wheels 102 roll along the inside wall of the pipeline being inspected to maintain the guide centralizers “centered” within the pipeline. A collapsible exciter unit centralizer 200 is positioned between collapsible guide centralizers 100 to “center” the exciter unit centralizer relative to the interior of the pipeline. The exciter unit centralizer 200 generates signals in the form of an alternating magnetic field that travel along the wall of the pipeline which in turn generates eddy current signals. The eddy current signals undergo a change if a discontinuity in the pipeline is encountered by the inspection tool 20, which signal change or deviation is detected by a collapsible detector unit centralizer 300 positioned between the collapsible guide centralizers 100.
