ABSTRACT:
A concrete pumping system includes a pipe extender unit for adjustment of a pipe length between two fixed points. The extender unit includes a ductile steel pipe telescoped over a standard pipe, with a seal therebetween. Four jaws of hardened steel have inner teeth on the center portion only which abutt the exterior of the pipe section. The pipe and jaws have end exterior shoulders. A two-piece annular clamp has spaced clamping legs engaging the shoulders to connect the members and force the jaw teeth into the outer wall of the pipe section to affix the pipe extender to the pipe section thereof. The teeth have a radial side and an inclined side joined by an outer flat land.
