Component Specifications

Definition
A header pipe is a primary distribution component in cooling header systems that collects and distributes coolant (water or air) to multiple branch lines or cooling circuits. It serves as the main manifold that ensures uniform flow distribution and pressure regulation across parallel cooling channels in industrial heat exchange applications.
Working Principle
Operates on fluid dynamics principles where coolant enters through a single inlet and is distributed through multiple outlets. The pipe's internal geometry and diameter maintain laminar flow to minimize pressure drop while ensuring equal distribution to all connected cooling circuits.
Materials
Stainless steel (AISI 304/316), carbon steel (ASTM A106), copper alloys (C12200), or aluminum alloys (6061-T6) depending on coolant type and operating conditions
Technical Parameters
  • Diameter 25-200 mm
  • Surface Finish Ra ≤ 3.2 μm for internal surfaces
  • Connection Type Flanged, threaded, or welded
  • Pressure Rating 10-40 bar
  • Temperature Range -20°C to 150°C
Standards
ISO 1127, DIN 2448, ASME B36.10M

Frequently Asked Questions

What is the difference between header pipe and manifold?

Header pipe refers specifically to the main distribution pipe in cooling systems, while manifold is a broader term that includes the complete assembly with valves, fittings, and branch connections. The header pipe is the core component of a cooling manifold system.

How to select the right header pipe diameter?

Diameter selection depends on total flow rate, pressure drop requirements, and number of branch circuits. Use flow calculations considering Reynolds number for laminar flow (Re < 2300) and consult ASME B31.3 for pressure piping design guidelines.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
