Yuhong Floating Head Shell and Tube Heat Exchanger
Ideal for Heavy Fouling & Large Temperature Difference Applications
Floating head shell and tube heat exchangers are specially designed to solve problems of severe fouling, large temperature differences, and high maintenance requirements in industrial processes. As one of the most versatile and reliable heat exchanger types, they are widely applied in oil & gas, refinery, petrochemical, power generation, metallurgy, and large-scale chemical processing. Yuhong provides professional design, manufacturing, installation, and after-sales service for floating head heat exchangers, helping customers achieve stable, efficient, and long‑life heat transfer.
Product Overview
Yuhong floating head heat exchangers consist of a shell, fixed tube sheet at one end, floating tube sheet at the other end, floating head cover, tube bundle, baffles, and shell channels. The key feature is that one end of the tube bundle is not fixed to the shell, allowing free thermal expansion and contraction. This structure completely eliminates thermal stress caused by large temperature differences between shell side and tube side fluids.
Compared with fixed tube‑sheet and U‑tube types, floating head heat exchangers allow the entire tube bundle to be pulled out for mechanical cleaning on both shell side and tube side. This makes them the best choice for fluids that tend to form heavy fouling, scale, or sediment.

Key Advantages
Free Thermal Expansion
The floating head structure allows the tube bundle to expand and contract freely, completely eliminating thermal stress, making it perfect for large temperature difference working conditions.
Excellent for Heavy Fouling Fluids
The entire tube bundle can be easily pulled out, enabling thorough mechanical cleaning and descaling on both tube side and shell side, greatly reducing downtime and maintenance cost.
High Structural Stability
Reinforced tube sheets, robust baffles, and reliable floating head sealing ensure stable operation even under high pressure, large flow, and long‑term continuous working conditions.
High Heat Transfer Efficiency
Optimized baffle design and tube arrangement improve turbulence and heat transfer coefficient, reducing energy consumption and operating cost.
Wide Applicability
Suitable for almost all types of fluids, including clean, fouling, corrosive, high‑temperature, high‑pressure, and volatile media.
Safe and Reliable Sealing
Professional sealing structure at the floating head prevents internal and external leakage, ensuring safe and stable operation.
