Component Specifications

Definition
A header is a critical distribution component in heating/cooling coil sections that connects the main supply/return piping to multiple parallel coil circuits. It ensures balanced fluid flow across all coil tubes, optimizing heat transfer efficiency in industrial HVAC, refrigeration, and process cooling systems. Headers are typically cylindrical or rectangular manifolds with precisely spaced branch connections.
Working Principle
Headers operate on fluid distribution principles: incoming fluid from main pipes enters the header chamber, where pressure equalization occurs before distributing through multiple outlets to parallel coil circuits. This ensures uniform flow rates and temperature distribution across all coil tubes, maximizing thermal exchange efficiency.
Materials
Carbon steel (ASTM A106/A53), stainless steel (304/316L), copper alloys (C12200), aluminum alloys (6061-T6). Material selection depends on fluid type, pressure, temperature, and corrosion requirements.
Technical Parameters
  • Diameter 50-300 mm
  • Branch Spacing 25-100 mm center-to-center
  • Connection Type Threaded, flanged, or welded
  • Pressure Rating 150-600 PSI
  • Temperature Range -40°C to 200°C
Standards
ISO 9001, ASME B31.1, DIN EN 13480
