A pipe loosening device and methods are shown. In one example, the pipe loosening device enables a method wherein a pipe to be replaced is deformed but not burst, and a portion of a sidewall of the pipe is forced outward into the surrounding soil to compact a local region of the surrounding soil and loosen the existing pipe. The pipe may then pulled from the ground along an axis of the pipe.

A rooftop support system including at least one support block. The support block includes a base configured to rest on the rooftop, and the base has a first base section and a second base section separated by a U-shaped recess that defines a first gripping feature. The support block includes first and second sidewalls unitary with the base and extending along a length of the support block, and the first and second sidewalls each define a second gripping feature. The support block also includes third and fourth sidewalls unitary with the base and extending along a width of the support block, and the third and fourth sidewalls each define a third gripping feature. An upper surface of the support block defines an elongate channel, and a pair of apertures are formed in the elongate channel with a coupling feature embedded therein.

A method of providing a transportable line pipe and distribution hose supply crossing assembly for use in supplying natural gas fueled drilling rig engines or fracking equipment with natural gas, electricity and pressurized air from mobile storage and vaporization facilities. A skid frame and ramp assembly are transported then assembled in end-to-end configuration for a continuous pipeline with a crossing ramp.

A segmental tube section structure having a length and a circumference, the segmental tube section structure including a plurality of tube segments extending the length in a longitudinal direction of the segmental tube section structure and extending in a circumferential direction of the segmental tube section structure, wherein each tube segment of the plurality of tube segments extends in the circumferential direction to span an equal arc of the circumference of the segmental tube section, and wherein each of the plurality of tube segments are connected to adjacent tube segments of the plurality of tube segments in the circumferential direction to form the segmental tube section structure.

The present disclosure provides a system for vertical deployment of leaching lines onto a slope of a mine leach pad. The system includes an elevated guidewire having a first end disposed at a top of the slope and a second end disposed at a bottom of the slope; the elevated guidewire being elevated above a surface of the slope; a deployment apparatus moveably coupled to the elevated guidewire and having one or more attachment mechanisms disposed thereon; and one or more leaching lines coupled to the attachment mechanisms; wherein movement of the deployment mechanism from the top of the slope to the bottom of the slope pulls the one or more leaching lines down the slope and deploys the one or more leaching lines vertically onto the surface of the slope.

A system for forming a pipeline including fused pipe having straight pipe elements and one or more non-linear pipe subassemblies positionable at respective preselected locations on a predetermined path. The system includes a straight pipe processing subassembly and a finishing subassembly. The system also includes a second fusing module for fusing the non-linear pipe subassembly with a selected one of the straight pipe elements to include the non-linear pipe subassembly in the fused pipe, the second fusing module being attachable to the finishing subassembly.

A rooftop support system including at least one support block. The support block includes a base configured to rest on the rooftop, and the base has a first base section and a second base section separated by a U-shaped recess that defines a first gripping feature. The support block includes first and second sidewalls unitary with the base and extending along a length of the support block, and the first and second sidewalls each define a second gripping feature. The support block also includes third and fourth sidewalls unitary with the base and extending along a width of the support block, and the third and fourth sidewalls each define a third gripping feature. An upper surface of the support block defines an elongate channel, and a pair of apertures are formed in the elongate channel with a coupling feature embedded therein.

The disclosure relates to a saddle support for use in above-ground pipeline construction in severe geological conditions, such as permafrost. The support provides structural stability and redistribution of a load from a pipeline to a pile foundation. The saddle support includes the spool coupled to four adjustable stands through electric insulating units. The stands can be adjusted to change a height and slope angle of the support and are fastened to a single-level pilework that supported by the pile foundation via flanges. The spool is a pipe having an external case and a heat-insulating layer. Longitudinal ribs are fastened to the spool to fasten the spool to the stands. The load-bearing structure of the spool resists axial and side movements of the pipeline and transfer the load absorbed by the spool to the pilework foundation via the electric insulating units on the adjustable stands.

A method of and apparatus for the rapid deployment of a fracturing water transferring system, along with the rapid picking up and storage of such system after use. In different embodiments the method in includes the use of a tensioning system to retrieve one or more segments of lay flat hose.
