Distributor Plate / Nozzle Body

The Distributor Plate / Nozzle Body is a key component in gas distribution assemblies, serving as the main structural housing for inlet nozzles. It contains and supports internal flow channels, ensuring that gas is evenly distributed through multiple outlet ports. This component is designed to maintain structural integrity under operating pressure while precisely directing gas flow to downstream processes. The plate/body is manufactured from materials such as Stainless Steel 316L, Hastelloy C-276, or Titanium Grade 2, depending on the application's corrosion and temperature requirements. Key parameters include an operating pressure range of 1.0–1.6 MPa, nominal diameters from DN15 to DN300 (ISO 6708), flow coefficients (Cv) from 2.5 to 120 (ISO 5167), and operating temperatures from -40°C to 85°C. Surface roughness is specified as Ra 0.8–1.6 μm (ISO 4287), and tolerances are ±0.05 mm (ISO 2768-m). The component's weight ranges from 0.5 to 15 kg, and leakage rates are 0.01–0.1 mL/min. Seat hardness is 40–50 HRC (ASTM E18), and the connection type is flanged (ISO 7005). These values are reference ranges for directory purposes; actual specifications must be confirmed with the manufacturer for the specific model and application. The component is used in chemical manufacturing processes where reliable gas distribution is critical. Proper selection requires consideration of operating conditions, media compatibility, and system design. Verification of material grades, standards compliance, and performance parameters is essential before installation. Maintenance signals include increased pressure drop, uneven flow distribution, or visible wear on sealing surfaces. Failure boundaries include exceeding pressure or temperature limits, which can lead to deformation or leakage.

Gas enters through the inlet connection and is distributed through internal channels within the plate/body structure. The geometry of these channels and the arrangement of outlet ports ensure even distribution of gas flow. The component withstands system pressure while maintaining precise flow patterns through its engineered internal passages. The design of the distributor plate/nozzle body is critical for achieving uniform gas distribution, which is essential for process efficiency and safety. The internal flow paths are machined to exact tolerances to minimize pressure drop and prevent channeling. The component's structural design ensures it can handle the mechanical stresses imposed by pressure and thermal expansion. Proper installation and alignment are necessary to maintain sealing integrity and prevent leakage. The working principle relies on the balance between inlet pressure, channel geometry, and outlet port sizing to achieve the desired flow distribution.
