Abstract:
A clamping structure configured to be secured about at least two pipes to securely hold the pipes adjacent each other during a pipeline assembly operation is disclosed. The device can be further used to adjust the relative positions of the two pipes and maintain the relative positions while the pipes are caused to be permanently affixed to each other. Some embodiments can include a clamping structure with a plurality of hingedly engaged clamp members and at least one spatial adjustment mechanism extending therefrom, the configurations of which may provide weld-access points that are conducive to the pipeline assembly operation.
Abstract:
Device for fitting two connectors at the end of two conduits, particularly in an aircraft, with a view to subsequent mutual connection of the connectors by a connecting pipe, including a body; a first support including temporary connector retainers that define an associated connector axis; an opposite second support including temporary connector retainers that define an associated connector axis; structure for moving the first support in translation relative to the body parallel to the associated connector axis, between a retracted position and a deployed position. A method of establishing fluidic communication between two conduits in an aircraft, including fitting two connectors at the end of the two conduits by such a device.
Abstract:
A support assembly for constructing and staging a pipeline for installation in a trench. The support assembly includes one or more stacks of support segments. A support segment for the support assembly. Method of using and making the support segments.
Abstract:
An alignment device is configured to receive, in a generally aligned configuration, workpieces which are to be joined together. In addition, the device is further configured such that, in use of the device, a joining line between the two workpieces is visible for checking alignment, and such that, in use of the device, each workpiece can be marked at a predetermined distance from the joining line. The device and a method of alignment using the device are particularly suited to the joining of pipes in the construction of marine vessels.
Abstract:
A laser target assembly, which doubles as a pipe plug, has an outer sheath with a first end that fits within the end of a cut section of pipe, and a second, larger-diameter end that fits into the bell of an uncut section. A circular interior panel, made of tough plastic, is positioned in about the middle of the sheath perpendicular to its central axis. A lower half of the panel, which functions as the target, is opaque; the balance is transparent. A target scale, having evenly-spaced linear markings, is provided on the opaque portion of the panel. A bubble level, positioned within the larger-diameter end adjacent the panel, enables a pipe layer to position the target scale in a vertical orientation. Interior handles are used to adjust axial alignment of target assembly and remove the target assembly when it is installed within a bell.
Abstract:
A pipeline support for use in severe geological conditions such as permafrost provides stability, strength and immovability of the pipeline support under relatively high pressure and that that allows an adjustment of a height or slope of the pipeline support. A method of using the support includes controlling the height or slope angle of the support during operation of the pipeline support. A spool of the support is installed and fixed on two support axes that are transverse beams installed in support frames and that can be moved along with the support spool. After that, movable power-operated mechanisms are positioned under each support axis. These mechanisms lift or lower the spool and support axes to the desired height and slope. The support axes are then fixed in frames at the desired height and spool slope angle.
Abstract:
A device 20 used to join two pipes 22,22′ positioned end to end. The device comprises two parallel jaws 24,24′ holding the pipes mounted in combination with means of rods 28 linking the two jaws. One jaw is fixed 24 while the other jaw is mobile 24′; at least one rod is provided with means of rack wherein means of pinions 34 are moved while pulling the mobile jaw 24′ towards or away from the fixed jaw until the pipes are connected. Each jaw is provided with means of spacing 42 their claws for adjusting their opening with the section of the pipes. Those means of spacing claws comprise a transversal bar 44 mounted between the claws and adapted to move, transversally along longitudinal slots made in the claws, thus spacing or moving closer the claws and then determining a sufficient opening corresponding with the pipe section.
Abstract:
An attachment that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break-out (i.e. disconnection or disassembly) from another section of pipe and/or make-up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.
Abstract:
A pipe laying machine is disclosed. The example pipe laying machine includes a platform configured to move continuously relative to the ground and a pipe connector section configured to slide along a portion of length of the platform relative to the platform. The pipe connector section includes an upstream stopper and a downstream pipe connector section configured to slide along a portion of a length of the pipe connector section relative to the pipe connector section. The upstream stopper is configured to prevent a bell mouth of a bell end of an upstream pipe from passing through. The downstream pipe connector section includes a downstream clamp, which is configured to grip a spigot end of a downstream pipe. The downstream pipe connector section is configured to slide toward the upstream pipe to connect the upstream pipe with the downstream pipe.
Abstract:
A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.
