Product Description
Carbon Steel Shell and Tube Heat Exchanger
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| Floating Head | One tubesheet free to move; entire bundle can be withdrawn for inspection and mechanical cleaning.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 |
| Channel | Distributes tube-side fluid | Removable for tube end inspection and cleaning |
| Saddles / Supports | Supports vessel weight; accommodates thermal expansion | 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)
- Lubricating oil, hydraulic oil, turbine oil cooling
- Low-pressure steam condensation and heating
- Cooling/heating of gases such as natural gas, air, and nitrogen
- Hydrocarbon media (crude oil, fuel oil, light hydrocarbons)
When to Consider Material Upgrades
- Media containing chlorides (e.g., seawater, high-chlorine cooling water) → Recommended upgrade to stainless steel or copper-nickel alloy
- Strongly acidic (pH<4) or strongly alkaline (pH>10) media → Consider stainless steel, duplex steel, or nickel-based alloys
- Media contains hydrogen sulfide (H₂S) in humid environment → Must meet NACE MR0175 requirements; sulfur-resistant materials may be necessary
- Long-term exposure to high-temperature oxidizing environments (>400°C) → Consider Chromium-Molybdenum Alloy Steel (e.g., 1¼Cr-½Mo)
Extended Corrosion Protection Options
- Coating Protection: Epoxy or phenolic coating on tube sheets and shell inner walls
- Sacrificial Anodes: Zinc anodes installed in seawater coolers
- Chemical Treatment: Optimized water treatment schemes, controlling pH and dissolved oxygen
Core Advantages & Customized Services
- Design on Demand: Precise thermal and mechanical design based on your process data to ensure performance meets specifications
- Flexible Material Selection: Combining different materials in the same unit, balancing cost and corrosion resistance
- Standardization and Customization: TEMA standard sizes available, plus complete custom designs for new or replacement projects
- Comprehensive Quality Documentation: Complete Material Quality Reports, Procedural Qualification Reports, Non-Destructive Testing Reports, and ASME data reports
- Optional Value-Added Services: Hydrostatic testing witnessing, third-party inspection, on-site installation guidance
Typical Application Areas
- Oil Refining: Crude oil preheating, top condensation, product cooling, reboilers, lubricating oil cooling
- Natural Gas Processing: Interstage cooling, gas dehydration and regeneration heaters
- Power Industry: Generator air coolers, turbine lubricating oil cooling, transformer oil cooling, closed-loop circulating water coolers
- HVAC: Boiler heat exchangers, district heating heat exchange stations, chiller condensers/evaporators
- Industrial Manufacturing: Air compressor aftercoolers, hydraulic system coolers, process water cooling/heating
- Marine & Offshore: Diesel engine coolers, central cooling systems (closed-loop freshwater side)
