Challenges of tube sheets in seawater desalination equipment

Tube sheets in seawater desalination equipment face three core challenges:
Material corrosion: The high-salt, high-humidity environment accelerates tube sheet corrosion, requiring the use of corrosion-resistant materials such as titanium alloys.

Structural stress: Tube holes weaken the rigidity of the tube sheet, and stress concentration at the edges easily leads to cracks, requiring optimization of the tube hole layout.

Process precision: The gap control between the tube holes and heat transfer tubes directly affects the connection quality, requiring strict control of processing accuracy.
