Component Specifications

Definition
A header body is a structural component within headers or manifolds that serves as the main distribution or collection point for fluids (liquids or gases) in industrial systems. It features multiple inlet/outlet ports and internal passages designed to optimize flow distribution, pressure equalization, and thermal management. Engineered for high-pressure applications, it ensures uniform fluid delivery to multiple branches while minimizing pressure drops and turbulence.
Working Principle
The header body operates on fluid dynamics principles, using internal channels to divide or combine flows from a single source to multiple destinations (or vice versa). It maintains system pressure and flow balance through precisely engineered port configurations and internal geometries, often incorporating features like flow straighteners or pressure-equalizing chambers to enhance performance.
Materials
Typically manufactured from carbon steel (ASTM A106), stainless steel (AISI 304/316), aluminum alloys (6061-T6), or ductile iron. Material selection depends on fluid compatibility, pressure requirements (up to 6000 psi), temperature range (-50°C to 400°C), and corrosion resistance needs.
Technical Parameters
  • Leak Rate < 1x10^-6 mbar·l/s
  • Surface Finish Ra 0.8-3.2 μm
  • Pressure Rating 150-6000 psi
  • Connection Types NPT, BSPP, SAE, Flanged
  • Temperature Range -50°C to 400°C
  • Port Configurations 2-24 ports
Standards
ISO 12151, DIN 2353, SAE J514, ASME B16.11

Frequently Asked Questions

What is the difference between a header body and a manifold?

A header body is a specific component within a manifold assembly that serves as the primary distribution/collection point, while a manifold refers to the complete system including valves, fittings, and controls.

How do I select the right header body material?

Consider fluid compatibility, operating pressure/temperature, corrosion requirements, and industry standards. Stainless steel is common for corrosive environments, while carbon steel suits high-pressure hydraulic applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
