YUHONG GROUP Orders of Tube Bundles For Heat Exchangers

Tube Bundles Key Design Features

The design of a tube bundle is a complex engineering task that balances thermal performance, mechanical integrity, pressure drop, material cost, and maintenance requirements.

1.Tube Layout and Arrangement

This refers to how the tubes are positioned within the shell, which significantly impacts heat transfer efficiency, cleaning accessibility, and pressure drop.

Layout Patterns:Triangular (or Rotated Square) (30°) / Square (90°) / Rotated Square (45°).

2. Heat Exchanger Tubes

The physical characteristics of the tubes themselves are fundamental to performance.

3.Baffle Design

Baffles are plates placed in the shell to direct shell-side flow across the tube bundle. They are critical for controlling flow, pressure drop, and preventing tube vibration.

Types of Baffles: Segmental Baffle (Single, Double, Triple) / Orifice Baffle  / Rod Baffle / Helical Baffle / Longitudinal Flow Baffle (No Baffles).

4.Tube-to-Tubesheet Joint

This is a critical mechanical and leak-proof connection where the tubes are joined to the stationary and/or floating tubesheets.Expansion / Welding / Both all.

5. Type of Bundle Construction

Fixed Tubesheet / U-Tube Bundle / Floating Head Bundle.
