Fluid Passage: Flow Capacity 0.1-500 L/min, Diameter 5-50 mm

Component Specifications

Definition

A fluid passage is a critical internal component of a header body designed to transport liquids or gases with controlled pressure, velocity, and direction. It features specific geometries (diameter, length, cross-section) to minimize turbulence, pressure drops, and contamination while ensuring efficient flow distribution to connected systems.

Working Principle

Operates on fluid dynamics principles, utilizing pressure differentials to move fluids through the passage. The design ensures laminar or controlled turbulent flow to reduce energy loss and maintain system efficiency, often incorporating smooth internal surfaces and optimized bends to prevent cavitation and erosion.

Materials

Typically made from corrosion-resistant materials: stainless steel (e.g., AISI 316L), brass, aluminum alloys, or engineered plastics (e.g., PTFE, PEEK) depending on fluid compatibility, pressure, and temperature requirements.

Frequently Asked Questions

What factors determine the material choice for a fluid passage?

Material selection depends on fluid type (corrosive, abrasive), operating pressure, temperature, and compatibility requirements to prevent leaks or degradation.

How does passage geometry affect system performance?

Geometry influences flow rate, pressure drop, and turbulence; optimized designs reduce energy consumption and prevent issues like cavitation or clogging.
