Tube Sheet
A Tube Sheet is a crucial component in Shell & Tube Heat Exchangers, responsible for holding the heat transfer tubes in place and separating the hot and cold fluids to prevent cross-contamination. Proper tube sheet design and material selection directly impact the efficiency, durability, and thermal performance of the heat exchanger.
At Rahavard Saei, we manufacture high-precision tube sheets using carbon steel, stainless steel, titanium alloys, and nickel alloys, ensuring high mechanical strength, corrosion resistance, and long service life. Our tube sheets comply with TEMA, API 660, and ASME Sec VIII standards, guaranteeing superior performance in high-pressure and high-temperature applications.

How It Works
A Tube Sheet is a flat, machined plate that serves as the foundation for securing heat exchanger tubes within the shell of the heat exchanger. It plays a crucial role in separating fluid paths and ensuring mechanical stability under extreme conditions.
Key Components & Functions
- Tube Holes – Precision-drilled to accommodate heat exchanger tubes, ensuring a tight and secure fit.
- Tube-to-Tube Sheet Joints – Created through welding, rolling, or expansion techniques to prevent leaks.
- Corrosion Protection – Optional cladding and coatings can be applied to enhance resistance in aggressive environments.
- Support & Alignment – Works alongside baffles and tie rods to maintain proper tube spacing and optimize heat exchange.
During operation, hot and cold fluids flow through separate channels, transferring heat across the tube walls while remaining completely isolated by the tube sheet structure. The material selection and precision engineering of the tube sheet ensure high-efficiency thermal exchange, minimal thermal stress, and extended equipment lifespan.
