This invention relates to an improved component (10) for replacing pipes, in particular underground pipes. The invention also relates to a trenchless method of removing pipes using the improved component, and a kit of parts for use in removing pipes. The improved component (10) is securable to a cable (14) and has a body (30) with a recess (26) to accommodate the end (18) of the pipe (12) in use, the recess being surrounded by a collar (24). The improved component is a two-part component, the first part (20) being securable to the cable (14) and the second part (22) including the body, the two parts being made of different materials. There is also provided a kit of parts including cooperating alignment elements of standard dimensions, and a method of removing an underground pipe.

A method and apparatus for connecting pipe sections or repairing two separated pipe sections is provided, including for extruded chopped filament pipe (“ECFP”). An apparatus having a sealable connecting jacket is provided, which includes a mold configured to fit around a cut section of ECFP and receive a resin or other material through an input, and a curing system, such as a hot water intake surrounding the mold to heat and cure the resin forming the new pipe section.

A slip coupling tool having an interior surface sized for receiving a pipe. The coupling tool includes a semi-annular collar sized to engage an exterior surface of the pipe. The collar extends to a rearward end face sized and shaped for aligning with an end of the slip coupling when the collar receives the pipe and the inner surface of the collar engages an exterior surface of the pipe. The slip coupling tool includes a striking plate extending outward from the collar. The striking plate has an impact surface spaced from the collar for impacting the coupling tool to drive the slip coupling into position along the pipe. The slip coupling tool includes a handle extending outward from the collar for manipulating the tool into position while impacting the impact surface of the striking plate to drive the slip coupling into position along the pipe.

A broken pipe extractor for removing a broken pipe from a pipe joint includes a hollow pipe body, a first blocking block, a second blocking block, and a hook needle assembly. The first blocking block is located in the pipe body for fixing one end of the pipe joint. The first blocking block defines a through hole. A diameter of the through hole is greater than or equal to an inner diameter of the pipe joint. The second blocking block is movably fixed to one end of the pipe body for fixing another end of the pipe joint. The hook needle assembly is configured to be inserted through the through hole of the first blocking block and extend to the broken pipe to remove the broken pipe.

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 pipe fitting system, including a first pipe section with at least one male end, a second pipe section with at least one female end, and a connecting means for releasably connecting the pipe sections together such that the male end is at least partially received within the female end. The connecting means comprising releasably engageable first and second connectors associated with the first and second pipe sections respectively, wherein the first connector comprises at least one outwardly extending protrusion and wherein the second connector comprises corresponding recesses adapted to releasably receive the or each protrusion of the first connector. The pipe fitting system is suitable for applications such as end of line connections, repair/replacement of fixed existing pipes, and in enabling temporary removal of pipes for maintenance or access purposes.

A broken pipe extractor for removing a broken pipe from a pipe joint includes a hollow pipe body, a first blocking block, a second blocking block, and a hook needle assembly. The first blocking block is located in the pipe body for fixing one end of the pipe joint. The first blocking block defines a through hole. A diameter of the through hole is greater than or equal to an inner diameter of the pipe joint. The second blocking block is movably fixed to one end of the pipe body for fixing another end of the pipe joint. The hook needle assembly is configured to be inserted through the through hole of the first blocking block and extend to the broken pipe to remove the broken pipe.

A kit comprising an adapter, having a slip end and a reverse-threaded end, and a pipe nipple having standard threads on one end and reversed threads on the other end. And the kit has PVC or other pipe cement, fittings with standard slip threaded connections blades, saws, cutters, or other irrigation pipe cutters, and valves, among other components.

A method for repairing a valve manifold with the steps of cutting a pipe system near a broken component (such as a valve); connecting a slip end of an adapter having a slip end and a reverse-threaded end to the system (sometimes gluing the connection with cement); removing the broken component from the system; attaching a replacement for the broken component; supplying a pipe nipple having a threaded end and a reverse-threaded end; inserting the pipe nipple into the normal threaded end and the reverse-threaded end; and tightening the pipe nipple to yield sealed joints.

A pipe fitting replacement device for rapid replacement of a damaged pipe fitting includes a shell, which has a plurality of orifices positioned therein. Each of a plurality of fasteners is engaged to the shell and extends from a respective orifice. The shell is sized and shaped so that the shell is complementary to an existing pipe fitting positioned in a piping network. Each fastener can have inserted therein a respective terminal pipe segment, which results from removal of the existing pipe fitting from the piping network. The fastener sealably engages the respective terminal pipe segment.

The methods and devices described herein are for repairing a break in a pipe and also provide means for adding additional pipes to an existing pipe. According to a first embodiment, a pair of end connectors are installed on the broken ends of a pipe and then a sleeve is slid over the gap between the two broken ends. According to a second embodiment, two half cylinder connector pieces are placed around a broken pipe and then a cylindrical sleeve is placed over the top. According to a third embodiment, two half cylinder connector pieces are glued to each other and the broken pipe, one of the half cylinders having a branch for installing an additional pipe to the pipe system.
