Land Area: Orifice Diameter 0.5-10 mm, Land Width 1-5 mm

Component Specifications

Definition

A land area in an orifice array refers to the flat, raised surface surrounding individual orifices or holes in a perforated plate or similar component. This area is precisely machined to maintain structural integrity, ensure proper sealing when mounted, and control fluid or gas flow characteristics by defining the geometry between adjacent orifices. It plays a critical role in distributing flow evenly, reducing turbulence, and maintaining pressure differentials across the array in applications such as filtration, spraying, or metering systems.

Working Principle

The land area functions by providing a defined spacing and structural support between orifices, which influences the flow path and resistance. It ensures that fluid or gas passes through the orifices with minimal interference, promoting laminar flow and accurate distribution. The width and surface finish of the land area affect pressure drop, flow rate, and efficiency, making it essential for optimizing performance in systems requiring precise control.

Materials

Typically made from stainless steel (e.g., 304, 316), aluminum alloys, or engineered plastics (e.g., PTFE, polycarbonate), selected based on corrosion resistance, strength, and compatibility with process fluids.
