1. A flow restrictor system for pressure relief in a fluid conduit, the system comprising:
a first flow restrictor comprising:
a sleeve having an inlet end, an outlet end, and a longitudinal bore therebetween,
an insert positioned within the longitudinal bore and sealed against an inner wall thereof, the insert comprising a plurality of longitudinal perforations that provide fluid passage through the longitudinal bore, and
a plurality of ports positioned radially through the sleeve, each port in fluid communication with one of the plurality of longitudinal perforations, wherein each port comprises an adjustable plunger configured to move within the port to adjustably restrict fluid flow through the one of the plurality of longitudinal perforations,
wherein the insert comprises a bypass port configured to provide fluid flow that bypasses the plurality of longitudinal perforations, the bypass port is configured to be maintained in a closed configuration by a piston, and the piston is configured to open the bypass port in response to a high-pressure condition.
