TRANSCRIPT
Design and manufactureof f low restriction orif ices
COMPLEX SOLUTIONS> Thermophysical properties calulcations
(Cp, viscosity, compressibility factor…) taking into account fluid phases
> CFD simulation
ENGINEERING & DESIGN CAPABILITY > Based on ISO5167, BS1042, ASME.MFC.3M
industry standards as for the orifice plate> Calculation according to the PED 97/23/CE
Pressure Equipment Directive > Manufacturing of restriction orifice
complying with ASME, CODAP, CODETI> 2D drawing, 3D layout plan software
INSPECTION & TESTS> Hydrostatic testing to check the tightness
and the strong performance of restriction orifices at required pressure levels

DELTAFLUID is established near the oil-field of Lacq, in the south of France.The company has developed a recognized expertise in designing and manufacturing of a full range of primary flow elements and pressure / flow restriction equipment dedicated to the process industry.More than 10.000 devices are installed worldwide.
TRUSTED NAMES RELY ON US
Limited to 85 dB (A) according to international noise standards.
Flow velocities with single hole orifice plates
> Restriction orifices are designed accurately taking into account all the relevant operating conditions and specific parameters such as noise, cavitation and critical flow.
> Incorrect design and calculation of restriction orifices without considering these parameters can lead to costly replacement of equipment.
> Used to manage pressure drops or to restrict flow rates in a pipe work> Multi-stage and/or multi-holes restriction orifices used for high pressure and/or high noise
applications.When the desired pressure drop cannot be achieved by a single plate, a multi-stage restriction orifice assembly is required. It is composed of several orifice plates, each of them reducing the fluid pressure to its maximum capacity. The orifice plate can be a single-bore or a multi-bore plate if the noise level is critical.

Damage of the orifice edge
Excessive noise and vibration Erosion of the plates and the tube
Damage of the entire restriction orifice
During the design stage, calculations are performed to avoid cavitation and choked flow at each stage of the flow restriction.
Multi-holes restriction orifices are implemented to meet this demand : increase the number of orifices in order to reduce the noise level.
CAVITATION CHOKED FLOW OR CRITICAL FLOW
Occurs for a liquid when large pressure drops are required.
Occurs for a gas when a big pressure drop is required and so sonic conditions can be reached.
