Tube sheet partitions that separate fluid passes in shell-and-tube heat exchangers for optimized thermal performance.
Pass partitions are structural components installed within tube sheets or headers of shell-and-tube heat exchangers to create multiple fluid passes. They direct the tube-side fluid through specific tube bundle sections in a predetermined sequence, controlling flow path length and velocity to achieve desired heat transfer coefficients and temperature profiles. These partitions are precision-engineered to withstand thermal expansion, pressure differentials, and corrosive environments while maintaining leak-tight seals between adjacent passes.

Pass partitions create multiple tube-side fluid passes to increase velocity and improve heat transfer efficiency by optimizing flow path length and temperature differentials.
Properly designed partitions allow for tube bundle removal and cleaning while maintaining structural integrity; removable partitions are available for high-fouling applications.
Duplex stainless steels, nickel alloys, and titanium offer excellent corrosion resistance in chloride, acidic, or high-temperature environments per ASTM and NACE standards.
