Abstract:
A sleeve joint for connecting together two pipe sections of a high-pressure line, each pipe section comprising a fluid-tight inner jacket of a thermoplastic material and a reinforcing outer jacket, the two inner jackets being joined to one another by a fluid-tight weld, and the two outer jackets being joined to one another by the sleeve joint to provide continuous reinforcement along the pipe, the sleeve joint comprising:a) a two pairs of separable shells, one pair for each pipe section, each shell of each pair having an inner surface and having serrations on the inner surface to engage with the respective pipe section outer jacket; b) a clamp for each pair of shells to extend around and clamp the respective pair of shells so that the shell serrations to can grippingly engage the respective pipe section outer jacket; and c) at least one tensile element extending between and secured to each pair of clamped shells.
