Frequently Asked Questions:
A tube sheet is a thick, perforated metal plate used in heat exchangers, pressure vessels and boilers. It serves as a support structure that holds the ends of heat exchanger tubes in place, ensuring proper alignment, sealing and thermal transfer. Tube sheets are typically precision-machined to exact tolerances and made from corrosion-resistant or high-strength materials.
The primary function of a tube sheet is to securely anchor and seal the tubes within a heat exchanger or boiler, allowing for efficient heat transfer between fluids without leakage or cross-contamination. It also helps maintain structural integrity under high pressure and thermal stress.
Tube sheets can vary based on application, design and material requirements. Common types include:
- Fixed Tube sheets: Permanently attached to the shell
- Floating Tube sheets: Allow for thermal expansion
- Cladded Tube sheets: Bonded with corrosion-resistant metals
- Drilled/Grooved Tube sheets: Designed for enhanced tube fit and sealing
