Yuhong Group Co., Ltd. is a trusted manufacturer of thermal process equipment, delivering reliable shell and tube heat exchangers, pressure vessels, and air coolers to global industries. We also supply a full range of precision components, including tube bundles, U-tubes, finned tubes, heat exchanger tubes, and essential parts (tubesheets, baffles, heads, nozzles).
Product Overview
The shell and tube heat exchanger is the most widely used heat transfer equipment in industrial processing. Its robust construction, high efficiency, and adaptability to various pressures, temperatures, and fluids make it the preferred choice for demanding applications. Our exchangers are engineered to meet your specific process requirements, with designs available in fixed tubesheet, floating head, and U-tube configurations, each offering distinct advantages.
Heat Exchanger Types
Type
Description
Best Suited For
Fixed Tubesheet
Tubesheets are welded directly to the shell. Simple, economical design.
Clean services with low fouling potential and small temperature differences between shell and tube sides.
Floating Head
One tubesheet is free to move, allowing for thermal expansion and easy bundle removal.
High-temperature differentials, fouling services requiring frequent cleaning, and corrosive fluids.
U-Tube
Tubes are bent into a U-shape, eliminating one tubesheet. The bundle can expand freely.
Applications with high thermal expansion, where cleaning is primarily on the shell side, or for high-pressure tube-side fluids.
Material Options
We fabricate exchangers from a wide selection of materials to match your process media and environmental conditions:
Stainless Steel (304/304L, 316/316L) - Excellent corrosion resistance for chemical, food, and pharmaceutical applications.
Alloy Steel (e.g., 1¼Cr-½Mo, 2¼Cr-1Mo) - For high-temperature services in refining and power generation.
Nickel Alloys (Monel 400, Inconel 600/625, Hastelloy) - For extreme corrosion resistance in harsh environments.

Nozzles
SA105, SA182 F316L, etc.
Connections for process fluids, instruments, drains, and vents.
Technical Highlights
Precise Thermal Design: Thermal calculations using HTRI or similar specialized software ensure optimal performance.
Reliable Tube Connections: Composite process of expansion and welding ensures leak-free operation under severe conditions.
Maintainability Design: Floating head and U-tube designs allow for easy mechanical cleaning and maintenance.
Structural Integrity: Components checked against local wind and seismic loads for safe operation.
Quality Documentation: Comprehensive documentation including MTRs, PQRs, NDT reports, and ASME data reports.
Selection Considerations
Correctly selecting the heat exchanger type at the initial stage can prevent operational problems:
Thermal Stress: For temperature differences exceeding 50°C, consider floating head or U-tube designs to avoid thermal stress issues.
Scaling Risk: For shell-side media prone to scaling, select floating head or U-tube exchangers for mechanical cleaning capability.
Tube-Side Pressure: Under extremely high pressure conditions (>10MPa), U-tube heat exchangers offer safer and more economical solutions.
Material Compatibility: Consider thermal expansion coefficients and weld compatibility to avoid cracking or galvanic corrosion.
Application Areas
Petroleum Refining: Crude oil preheating, tower top condensation, product cooling
Chemical and Petrochemical Industries: Reactor feed/discharge heat exchange, solvent recovery
Power Industry: Lubricating oil cooling, generator air cooling, turbine extraction steam condensation
HVAC & Refrigeration: Chiller evaporators/condensers, heat pump systems
Food and Pharmaceutical Industries: Pasteurization, pure steam condensation, process fluid heating/cooling
