When a reduction of pressure or a limitation of the flow rate is required a restriction orifice must be inserted into the pipeline. Our technical department will evaluate the correct design for the restriction orifice, depending on customer requirements and flow conditions.
If high delta pressures, a change in phase or sonic issues can occur, a complex design will be required. The solution in these cases is to devide the delta pressure in several steps, avoiding all the issues has to be generated by these factors. This solution is called multi-step restriction orifice.
