Distribution Ducts: Diameter Range 10-500 mm

Component Specifications

Definition

Distribution ducts are precision-engineered components within distribution manifolds, designed to channel liquids, gases, or mixed-phase media from a central source to designated outlets. They ensure controlled flow distribution, pressure management, and minimal turbulence across connected systems in manufacturing equipment.

Working Principle

Distribution ducts operate on fluid dynamics principles, utilizing internal geometry (diameter, bends, branching) to guide media from a manifold's inlet to multiple outlets. They maintain consistent pressure and flow rates through engineered cross-sections, often incorporating flow-straightening features or dampeners to reduce turbulence and ensure uniform distribution.

Materials

Stainless steel (AISI 304/316), aluminum alloys (6061-T6), engineered plastics (PTFE, PVDF, polypropylene), or composite materials, selected based on chemical compatibility, pressure ratings (typically 10-150 psi), and temperature ranges (-40°C to 200°C).

Frequently Asked Questions

What are the key design considerations for distribution ducts?

Key considerations include material compatibility with media, pressure drop calculations, thermal expansion allowances, corrosion resistance, and ease of maintenance/cleaning, particularly in sanitary applications.

How do distribution ducts differ from standard piping?

Distribution ducts are specifically engineered for multi-outlet flow division from a single source, with optimized geometry for balanced distribution, whereas standard piping typically handles linear transport between two points.
