Component Specifications

Definition
The Frame/Header is a critical structural component in heat exchanger systems, particularly in cooling towers and plate heat exchangers. It consists of a rigid frame that supports the entire assembly and headers that distribute fluid to and from the heat transfer plates or surfaces. This component ensures proper alignment, maintains pressure integrity, and provides mounting points for other system elements while withstanding thermal expansion, mechanical loads, and environmental conditions.
Working Principle
The Frame/Header functions by providing structural support to maintain alignment of heat transfer elements while distributing fluid through inlet and outlet headers. The frame absorbs mechanical stresses and thermal expansion forces, while headers ensure even fluid distribution across all heat transfer surfaces to maximize thermal efficiency and prevent flow maldistribution.
Materials
Carbon steel (ASTM A36/A283), Stainless steel (304/316L), Aluminum alloys (6061-T6), Galvanized steel, Powder-coated steel for corrosion resistance. Material selection depends on fluid compatibility, temperature range, and environmental conditions.
Technical Parameters
  • Mounting Type Bolted or welded connections
  • Surface Finish RAL 9010 standard, other options available
  • Pressure Rating 10-25 bar standard
  • Weight Capacity 500-5000 kg depending on configuration
  • Frame Dimensions Customizable to heat exchanger size
  • Header Port Sizes DN25 to DN300
  • Temperature Range -20°C to 200°C
Standards
ISO 15547, ASME BPVC Section VIII, DIN EN 13445, API 661

Frequently Asked Questions

What is the difference between frame and header in heat exchangers?

The frame provides structural support and maintains alignment of the entire assembly, while headers are specifically designed for fluid distribution to and from the heat transfer surfaces.

How do I select the right material for Frame/Header components?

Material selection depends on fluid compatibility (corrosion resistance), operating temperature, pressure requirements, and environmental conditions. Stainless steel is common for corrosive fluids, while carbon steel with protective coatings is used for cost-effective solutions in non-corrosive environments.

What maintenance is required for Frame/Header assemblies?

Regular inspection for corrosion, checking bolt tightness, verifying alignment, and cleaning of header ports to prevent clogging. Annual visual inspections and torque checks are recommended.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
