  • Patent number: 7083204
    Abstract: A coupling for joining metal pipes or pipe sections end-to-end to form a pipe assembly. A plastic cuff is formed on one of the pipe ends and a mating, second plastic cuff is formed on the other pipe end. In one embodiment, a wire hoop is mounted over each pipe end, the hoops are rotatable around the associated pipe ends to align the hoops, and bolt assemblies spanning the two hoops are used to tighten the hoops axially, to thereby clamp the pipe ends and compress the cuffs between the pipe ends and provide a leak-proof joint. The cuffs are selected from configurations including tongue-and-groove and bell-and-spigot. The cuffs can be formed on the pipe ends in the shop, then the pre-cuffed pipe sections can be readily assembled into stable, leak-proof, corrosion-resistant lengths of pipe in the field.

  • Patent number: 6854768
    Abstract: A continuous flexible conduit is formed from like-configured components, each having a male joint member and a female joint member with a passageway extending therethrough. The female joint member is over-molded about a corresponding male joint member to form a substantially fluid-tight articulating joint. In a method of producing the flexible conduit, a single-shot molding process is used to form each like-configured component, with each newly formed component indexed within the single-shot mold so that the male joint member is within the female mold cavity for the formation of the next component. In an alternative embodiment, a continuous conduit is formed of two different sets of like configured components—one set having only female joint members and the other set having only male joint members. A two-shot molding process is described for continuous production of the flexible conduit using these two sets of components.
