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 pair (16), (17) of long straight end pipe sections interconnected by a plurality (18), (19), (20) of shorter intermediate pipe sections and by swivel joints (25). The two end pipe sections are aligned generally parallel with the telescoping boom and the intermediate pipe sections flip-flop to change their direction of alignment as the pipeline is extended and retracted. The flip-flop feature provides a maximum change in length of the pipeline between the extended and the retracted positions with a minimum number of pipe swivel joints. |
