Fixed Tubesheet, Floating Head & U-Tube Designs | Economical ASME Fabrication for Oil, Gas, Power & HVAC Applications
Reliable Thermal Solutions at Competitive Value
Yuhong Group Co., Ltd. is a trusted manufacturer of engineered heat transfer equipment, delivering custom shell & tube heat exchangers, pressure vessels, and air coolers to global industries. We also supply precision replacement components, including tube bundles, U-tubes, finned tubes, heat exchanger tubes, and critical parts such as tubesheets, baffles, and heads, ensuring complete support for maintenance and new projects.
Cost-Effective Industrial Workhorse
The carbon steel shell and tube heat exchanger is the most widely specified thermal equipment across process industries, valued for its combination of reliability, thermal efficiency, and affordability. Constructed from ASME-approved carbon steel materials, these exchangers deliver robust performance in non-corrosive or mildly corrosive services involving water, steam, oil, gas, and various hydrocarbons. Our designs are available in fixed tubesheet, floating head, and U-tube configurations to match your specific process requirements.
Carbon Steel Heat Exchanger Selection Guide
Type
Design Characteristics
Best Suited Applications
Fixed Tubesheet
Tubesheets welded to shell; simplest and most economical construction. May include expansion joint for thermal stress relief.
Clean services with low fouling potential; moderate temperature differences (typically <50°C); water-to-water or steam-to-water applications.
Floating Head
One tubesheet free to move; entire bundle can be withdrawn for inspection and mechanical cleaning.
High temperature differentials; fouling services requiring regular cleaning; hydrocarbon and refinery applications.
U-Tube
Tubes bent into U-shape; single tubesheet; bundle expands freely without expansion joint.
High thermal expansion; high-pressure tube-side services; applications where shell-side cleaning is sufficient.
Material Specifications for Carbon Steel Construction
Component
Typical Material Standard
Key Characteristics
Shell & Channel
ASME SA516 Gr. 70
Pressure vessel quality steel; excellent weldability and toughness for structural integrity.
Tubes
ASME SA179
Seamless cold-drawn low-carbon steel; optimized for heat transfer and formability.
Tubesheet
ASME SA266 Gr. 2 (Forged) or SA516 Gr. 70 (Plate)
Forged provides superior strength for high-pressure applications; plate is economical for standard duties.
Baffles
ASME SA516 Gr. 70
Supports tubes and directs shell-side flow; thickness per TEMA standards.
Nozzles & Flanges
ASME SA105
Forged carbon steel; available in various pressure classes (150#, 300#, 600#, etc.).
Fasteners
ASME SA193 Gr. B7 / SA194 Gr. 2H
High-strength bolting for flange connections; corrosion-resistant coatings available.
Key Components & Their Functions
Component
Primary Function
Design Notes
Tube Bundle
Transfers heat between shell-side and tube-side fluids
Tube layout (triangular or square pitch) optimized for thermal duty and cleanability
Tubesheet
Secures tubes; forms pressure boundary
Thickness calculated for pressure loads and tube expansion forces
Shell
Contains shell-side fluid; provides structural support
May include expansion joint for fixed tubesheet designs with high temperature differential
Baffles
Enhances heat transfer; supports tubes against vibration
Segmental, double-segmental, or helical patterns available
Designed per ASME or customer-specific requirements
Engineering Advantages
Mature Material System: Comprehensive physical and mechanical properties ensure reliable thermal calculations and stress analysis, reducing design risk
Excellent Weldability: Materials such as SA516 Gr.70 and SA179 provide good welding process adaptability, ensuring quality and long-term reliability
Easy Maintenance and Repair: Localized corrosion or damage can be restored through welding repair or tube bundle replacement, controlling life-cycle costs
Extensive Standards Support: Full compliance with ASME, TEMA, and HEI standards ensures documented design, manufacturing, and inspection processes
Material Selection Guidance
Ideal Applications for Carbon Steel
Clean or treated cooling water (closed-loop water supply, boiler feedwater)
Industrial Manufacturing: Air compressor aftercoolers, hydraulic system coolers, process water cooling/heating
Marine & Offshore: Diesel engine coolers, central cooling systems (closed-loop freshwater side)
