Noise control - Import export

Orifice diameter: dimensioned according to the fluid, to the pressure drop to be achieved and to the flow going through the restriction. Plate thickness: calculated taking into account the pressure drop generated by the plate and the diameter of the pipework to prevent plate deformation. See more details in our Frequently Asked Questions. Noise: control of the estimated noise level at 1 m. In case of high noise level, refer to the multi-hole plate. Cavitation: The cavitation level is checked for each plate. In the presence of cavitation, a multi-stage restriction orifice alternative may be proposed depending on the operating conditions of the restriction. For more information on cavitation, see our Frequently Asked Questions. Critical flow or choked flow: if the fluid reaches its maximum speed when passing the restriction, its flow can not increase. A multistage solution can be proposed depending on the operating conditions of the restriction. For more information on critical flow
