A telescoping boom assembly supported articulated well service pipeline (10) for the transfer of pressurized fluids from service vehicles to petroleum wellheads for the treatment and stimulation of production oil wells. The boom assembly (12) is mounted on a truck, trailer or other suitable mobile transport, and the articulated pipeline (11) comprises a plurality of straight pipe sections interconnected by swivel joints (18) to provide the required rotational freedom and flexibility. The pipe sections are supported by a plurality of pipe carriers (16) each having a pair of rollers rotatably fastened to the carrier frame for moving the pipe carriers along the length of the boom assembly. The outermost pipe carries an outboard pipe and a cradle along the boom assembly until the carrier reaches the outer end of the boom assembly. The outboard pipe section is then lifted from the carrier cradle and the pipe section slides over a rounded support device to extend the outboard pipe section beyond the outer end of the boom assembly. |
