(54) | Flow nozzle assembly |
(57) The present invention generally provides apparatuses and methods for an improved
shunt nozzle which is part of an alternative pathway for a slurry to by-pass an obstruction
such as a sand bridge during gravel packing. In one embodiment, the nozzle has a hardened
insert that lines a surface of a hole in the shunt and seats on a surface of a wall
proximate the hole, thereby restraining movement of the insert relative to the shunt
for welding an outer jacket to the shunt.
