摘要： Multilayer fluid conduits are formed by adhering to a tubular outer surface of a metal pipe, a thermoplastic outer layer. The outer layer permits ends of the multilayer conduit to be joined together in leak-proof fluid conduit systems simply by adhering the conduit ends with compatible thermoplastic fittings. For fire protection systems, the preferred metal is steel, the preferred thermoplastic is CPVC and the preferred adhesive is heat activated. The adhesive coated metal pipe is preheated and the CPVC is extruded onto the outer surface of the heated metal pipe. Through the use of fire resistive CPVC, the multilayer conduit systems of the present invention can be installed in more severe fire threat areas than can existing, all plastic piping, including all CPVC piping systems. The conduit is assembled into systems on site simply by cutting and direct bonding with ordinary, all plastic fittings using appropriate bonding agents such as solvent based adhesives. CPVC fittings are preferred for fire protection systems.

摘要： A fire sprinkler piping system fitting including a polymeric body having at least a first tubular branch, a second tubular branch, and a third tubular branch. Each of the first, second and third tubular branches extend outwardly from a common junction. The first and second tubular branches are collinear and the third tubular branch is generally perpendicular to the first and second tubular branches. Each of the first, second and third tubular branches have a distal end opposite from the common junction. The fitting includes pair of internally threaded metal inserts. Each insert is at least partially molded into the distal end of a separate one of a first and second tubular branches. Each of the internally threaded inserts has a distal outer surface facing generally away from the common junction. The distal outer surfaces of the pair of internal threaded metal inserts is spaced apart a distance of between three inches and four inches. The distal end of the third tubular branch has a smooth internal bore to slidingly receive a smooth outer end of a length of pipe.

摘要： Systems and methods for evaluating a piping system for an improperly assembled fluid tight connection. Provided is a preferred joint assembly unable to hold fluid pressure in either one of a dry fit connection and partial seal connection. The joint assembly includes a coupler to identify a leak. More specifically, the coupler includes a substantially tubular wall portion having an outer surface, an inner surface and a channel disposed along one of the inner and outer surfaces. The channel has a first configuration for carrying a fluid between an interior of the piping system and an exterior of a piping system, and a second configuration to prevent fluid from being carried between the interior and the exterior of the piping system. The channel is further preferably convertible from the first configuration to the second configuration in the presence of a minimum amount of sealant material.
