Component Specifications

Definition
A manifold or header in injection spargers/diffusers is a critical fluid distribution component designed to evenly split a single inlet flow into multiple outlet streams or combine multiple inlets into one outlet. It ensures uniform pressure and flow distribution across all connected sparger/diffuser elements, optimizing gas or liquid injection efficiency in industrial processes like aeration, chemical dosing, or gas dispersion. Typically constructed from corrosion-resistant materials, it features precision-machined internal channels to minimize pressure drops and turbulence.
Working Principle
The manifold/header operates on fluid dynamics principles, using internal branching channels to distribute flow from a central inlet to multiple outlets. It maintains consistent pressure across all branches via engineered geometry (e.g., equal-length paths, tapered designs), ensuring uniform fluid delivery to sparger/diffuser elements. In injection systems, it may incorporate valves or regulators for flow control, enhancing dispersion accuracy in applications like wastewater treatment or chemical processing.
Materials
Stainless steel (e.g., 316L, 304), carbon steel, brass, or engineered plastics (e.g., PVC, PTFE) depending on corrosion resistance and pressure requirements. Materials are selected based on fluid compatibility, temperature range (-20°C to 200°C), and pressure ratings (typically 10-100 bar).
Technical Parameters
  • Inlet Ports 1-2
  • Outlet Ports 2-12
  • Flow Capacity 5-500 L/min
  • Connection Type Threaded (NPT, BSP), flanged, or welded
  • Pressure Rating Up to 100 bar
  • Temperature Range -20°C to 200°C
Standards
ISO 9001, DIN 11850, ASME B31.3

Frequently Asked Questions

What is the difference between a manifold and a header in sparger systems?

In sparger systems, a manifold typically refers to a component that splits flow into multiple branches, while a header often combines flows from multiple sources, but the terms are sometimes used interchangeably based on design.

How do I select material for a manifold/header?

Choose material based on fluid compatibility (e.g., stainless steel for corrosive chemicals), pressure/temperature requirements, and industry standards like ASME B31.3 for safety.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
