<p>A folding 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 support and the articulated pipeline comprises a plurality of long straight pipe sections interconnected by a plurality of pipe elbows and by swivel joints. Each of the pipe sections is supported by a corresponding boom section aligned generally parallel to the pipe section. The boom sections and their corresponding pipe sections are folded onto the service vehicle for transportation and are extended for connection to a wellhead. Supports between the ground and the boom sections reduce the loads transmitted to the service vehicle and allow the use of lighter and less costly boom assemblies.</p> |
