INDUSTRY COMPONENT

Tube Sheets / Plate Frames

Tube sheets and plate frames are structural components in heat exchangers that secure and separate fluid channels.

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)

Frequently Asked Questions

What is the difference between tube sheets and plate frames?

Tube sheets are used in shell-and-tube heat exchangers to secure tubes, while plate frames provide structural support and sealing in plate heat exchangers.

How are tube sheets manufactured?

Tube sheets are typically machined from forged plates with precision drilling, facing, and groove cutting operations to ensure dimensional accuracy.

What causes tube sheet failure?

Common failure modes include corrosion, erosion, thermal stress cracking, and improper tube-to-sheet joint integrity.
