The orifice is incorporated inside the hose and unless you dissect the hose, you are not going to find it. If you have the original hose, you would notice a clamped portion somewhere in between and that is where the orifice is located.
This is for regulating the fluid flow. When I fabricate hoses, I would remove this part from the OEM hose and install it inside the fabricated hose/
However I am not sure what the noise sounds like and there are other possibilities for noise problems when turning steering.
It can come from the pump itself, the pressure valve or even the reservoir. Any restriction in the delivery lines can result in insufficient fluid getting to the pump and this can result in noises.
Please consider a to help us answer more questions.
