Component Specifications

Definition
Tube sheets are thick plates with precisely drilled holes that hold heat exchanger tubes in place, creating a barrier between shell-side and tube-side fluids. Plate frames provide structural support and sealing surfaces for plate heat exchangers, maintaining pressure integrity and proper flow distribution across heat transfer plates.
Working Principle
Tube sheets function by mechanically securing tubes through expansion, welding, or rolling while maintaining a pressure-tight seal between fluid circuits. Plate frames apply compressive force to create gasket seals between plates, ensuring leak-free operation and proper plate alignment for optimal thermal performance.

Carbon steel (ASTM A516), stainless steel (304/316L), titanium (Grade 2), copper alloys (C70600), nickel alloys (Inconel 600), duplex stainless steels (2205)
