  • Patent number: 4488346
    Abstract: A pipe and sleeve telescoped joint with the pipe and sleeve in sealing engagement and keys embedded in both pipe and sleeve at their interface. The size and number of the keys are calculated from the size and strength of the pipe. The sleeve is sized and its strength selected from the strength of the pipe, and the sleeve ends are shaped to hold the joint circular when it is made. The apparatus includes means for holding the midportion of the sleeve circular when creating the joint, and for cooperating with the sleeve ends to keep them circular. The sealing engagement is created by firing a propellant into a substantially incompressible medium, like water, held by the apparatus in a cavity about the sleeve, and a piston separates the explosive propellant from the pressure medium.
