Component Specifications

Definition
A precisely engineered orifice opening is a critical flow control component within an orifice array system, designed to create a controlled pressure drop and regulate fluid flow rates through calibrated geometric restrictions. These openings feature specific diameter-to-length ratios, edge profiles, and surface finishes to achieve predictable flow characteristics according to Bernoulli's principle and continuity equations.
Working Principle
Operates on fluid dynamics principles where fluid passing through a constricted opening experiences increased velocity and decreased pressure, creating a measurable pressure differential proportional to flow rate. The orifice opening's geometry determines the flow coefficient (Cv/Kv) and discharge coefficient (Cd), enabling precise flow measurement and control through calibrated restriction.
Materials
Stainless steel (AISI 316/304), hardened tool steel, tungsten carbide, ceramic (alumina/zirconia), or engineered polymers (PTFE/PEEK) depending on application requirements for corrosion resistance, wear resistance, and temperature stability.
Technical Parameters
  • Surface Finish Ra 0.4μm to 1.6μm
  • Pressure Rating Up to 6000 psi (414 bar)
  • Temperature Range -40°C to 400°C
  • Diameter Tolerance ±0.01mm to ±0.05mm
  • Flow Coefficient Range 0.1 to 10.0 Cv

Frequently Asked Questions

What factors affect orifice opening performance?

Key factors include geometric accuracy (diameter, edge sharpness), surface finish, material properties, installation alignment, upstream/downstream piping configuration, and fluid properties (viscosity, density, temperature).

How is orifice opening size determined?

Size is calculated based on required flow rate, allowable pressure drop, fluid properties, and system conditions using standardized equations from ISO 5167 or ASME standards, often with safety factors for wear and fouling.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
