ABSTRACT:
An automated flowback system allows control and operation of the system from a remote location away from the dangers of high-pressure gases or abrasives traveling at high velocities that cause damage or failure to equipment piping valves. The system provides techniques and mechanical components installed in flowlines in any position without having to cut and thread, weld or fabricate pipe to fit. This system includes an expansion sub with axial adjusting lengths adequate to compensate for variations between two points. The expansion sub is secured and installed into position eliminating field cut and threading, welding or fabrication. The system also includes a blast barrel with an installed choke nipple, choke bean or choke insert with a chosen orifice size for multiple chambered ports. The blast barrel retracts between two fixed points without having to dismantle any connections or be removed from the fluid flow.
