Abstract: A telescoping boom assembly supported articulated well service pipeline for the transfer of pressurized fluids from service vehicles to petroleum wellheads for the treatment and stimulation of production oil wells. The boom assembly is mounted on a truck, trailer, or other suitable mobile transport, and the articulated pipeline comprises a plurality of long straight pipeline sections interconnected by a plurality of shorter pipe sections and by swivel joints. The inboard end of the pipeline is connected to a supply line by an inboard pipe and a pair of swivel joints. The pipeline can be folded into a cluster and tilted for storage adjacent the inboard end of the boom assembly and the clustered pipeline moved away from the service vehicle before unfolding the pipeline from the cluster.

Abstract: A telescoping boom assembly supported articulated well service pipeline for the transfer of pressurized fluids from service vehicles to petroleum wellheads for the treatment and stimulation of production oil wells. The boom assembly is mounted on a truck, trailer, or other suitable mobile transport, and the articulated pipeline comprises a pair of long straight end pipe sections interconnected by a plurality of shorter intermediate pipe sections and by swivel joints. 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.
