Component Specifications

Definition
The main header pipe is a critical component in collector header systems that serves as the primary distribution conduit for fluids (liquids or gases) to multiple branch lines. It functions as the central manifold that collects fluid from a single source and evenly distributes it to various downstream processes or equipment. In industrial applications, it ensures consistent pressure and flow distribution across parallel circuits.
Working Principle
The main header pipe operates on fluid dynamics principles, utilizing pressure differentials and cross-sectional area optimization to distribute fluid evenly to multiple outlets. It maintains laminar flow characteristics to minimize pressure drops and turbulence, ensuring uniform distribution across all connected branches. The pipe's diameter and length are calculated based on flow rate requirements and system pressure specifications.
Materials
Stainless steel (AISI 304/316), carbon steel (ASTM A106 Grade B), duplex stainless steel (UNS S31803), or corrosion-resistant alloys depending on application requirements. Wall thickness typically ranges from Schedule 10 to Schedule 80.
Technical Parameters
  • Diameter 50-300 mm
  • Surface Finish Ra ≤ 3.2 μm
  • Connection Type Flanged, welded, or threaded ends
  • Pressure Rating 10-100 bar
  • Temperature Range -20°C to 200°C
Standards
ISO 1127, DIN 2448, ASME B36.10M, EN 10216

Frequently Asked Questions

What is the difference between main header pipe and branch pipes?

The main header pipe is the primary distribution line that supplies fluid to multiple branch pipes. Branch pipes are smaller diameter lines that connect to the main header to deliver fluid to specific equipment or processes.

How do you calculate the optimal diameter for a main header pipe?

Diameter calculation considers flow rate, fluid properties, pressure drop limitations, and velocity constraints using formulas like Darcy-Weisbach equation or Hazen-Williams equation, with typical velocities of 1-3 m/s for liquids and 10-30 m/s for gases.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
