The tube sheet serves as a structural plate that secures heat exchanger tubes, maintains tube alignment, creates sealed boundaries between fluid circuits, and withstands pressure differentials and thermal stresses during operation.
Tubes are secured through tube rolling (mechanical expansion), welding (seal welding or strength welding), or a combination of both methods to ensure leak-tight joints that can accommodate thermal expansion.
Stainless steel (304/316), nickel alloys (Inconel), titanium, or clad materials with corrosion-resistant overlays are used when operating with aggressive fluids or high-temperature conditions.
