Techniques for implementing a pipeline system that includes a pipe segment and a pipe fitting. The pipe segment includes tubing, which includes an inner barrier layer that defines a pipe bore, a reinforcement layer implemented around the inner barrier layer to define a fluid conduit, and an outer barrier layer implemented around the reinforcement layer, and a tensile clip secured to the tubing such that clip legs of the tensile clip are secured around the reinforcement layer. The pipe fitting includes electrofusion material implemented to define a fitting bore and a tubing cavity in which the tubing is to be secured and a tensile hook partially embedded within the electrofusion material such that a hook bend extends into the tubing cavity, in which the hook bend matingly interlock with a loop end of the tensile clip to facilitate transferring tensile force between the reinforcement layer and the pipe fitting.

Disclosed herein is a piping system for an air conditioner, in which a refrigerant pipe being an air conditioning piping of a vehicle and a flange member are each made of a plastic material, and the refrigerant pipe and the flange member can be connected by laser fusing. That is, the present disclosure provides the piping system for an air conditioner, in which the refrigerant pipe and the flange member are each made of a plastic material having a vibration insulation effect and are connected by laser fusing which can prevent damage so that an effect of weight reduction and vibration insulation can be provided and a pressure loss of a refrigerant fluid can be minimized by maintaining a diameter of the refrigerant pipe to be constant with respect to an overall length of the refrigerant pipe.

Induction Weldable Pipe Connectors (IWPCs) (400) for electromagnetic induction welding with at least one plastic pipe (30). IWPCs (400) include a tubular induction weldable mounting (401) having an opposite pair of induction weldable sockets (404A, 404B), a tubular cover (406) externally mounted on the induction weldable mounting (401), and a tubular pipe tang (407) internally disposed in one induction weldable socket (404A, 404B) for destining an induction weldable socket (404A, 404B) as an induction weldable pipe socket (408A, 408B) for forced sliding insertion of a pipe end (31) thereinto. The cover (406) includes an opposite pair of thermally insulated induction weldable socket mouth rims (426A, 426B) for entrapping melted solder lining (412) inside the induction weldable mounting (401) during an electromagnetic induction welding operation, thereby ensuring improved welding.

The invention relates to a device (1) for connecting two fluid-channeling lines (10, 20), wherein the device has a through-bore (2) for advancing the fluid and two opposite line mounts (11, 21), which terminate at a predetermined distance (4) from one another within the device. Each of these line mounts (11, 21) is designed such that it is provided with a first part (12, 22), through which the through-bore (2) leads, and a second part (13, 23), which enclosed the first part (12, 22), an annular space (14, 24) therefore being formed between the first part (12, 22) and the second part (13, 23). Each of the two fluid-channeling lines, (10, 20) is arranged in one of the line mounts (11, 21) such that it has an inner cross section (16, 26) arranged, and fixed, with sealing action against the first part (12, 22) of the device and has an outer cross section (17, 27) arranged, and fixed, in the annular space (14, 24).

Provided is an electric power control apparatus of an electrofusion coupling pipe using a conductive polymer composite as a heating element and a method of controlling electric power using the same. The electric power control apparatus supplies electric power to the electrofusion coupling pipe using a conductive polymer composite as a heating element to detect resistance variation of the conductive polymer composite and then controls electric power supplied to the synthetic resin pipe electrofusion coupling pipe on the basis of the detected resistance variation.

Coupling piece for an outer end of a multilayered conduit, comprising a coupling pipe which is provided on the outer side with a radially upright wall, wherein the wall is widened in axial direction at a radial distance from the outer side of the body, wherein the outer side of the coupling pipe, the upright wall and the widened portion enclose an annular insertion space into which the outer end of the conduit can be directly inserted, and wherein the radial distance between the widened portion of the wall and the outer side of the coupling pipe at the position of the entry to the insertion space is such that it is equal to or greater than the wall thickness of the conduit, wherein an inner diameter of the coupling pipe increases in outward direction at the exit.
