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
TypeDescriptionBest Suited For
Fixed TubesheetTubesheets 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 HeadOne 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-TubeTubes 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:
  • Carbon Steel (SA516 Gr.70, SA106 Gr.B, SA266 Gr.2) - Economical choice for non-corrosive services.
  • 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.
Key Components & Specifications
ComponentTypical Material(s)Function & Design Notes
Tube BundleASME SA179, SA213 TP316L, etc.Primary heat transfer surface; tube size, wall thickness, and layout optimized for thermal duty.
Tubesheet(s)SA266 Gr.2, SA182 F316L, etc.Holds tubes in place; thickness calculated for pressure and tube loading.
ShellSA516 Gr.70, SA106 Gr.B, etc.Contains shell-side fluid; includes inlet/outlet nozzles and possibly expansion joint (for fixed designs).
BafflesSA516 Gr.70, SA240 316L, etc.Directs shell-side flow across tubes to enhance heat transfer and support tubes.
Channel / BonnetSA516 Gr.70, SA105, etc.Distributes tube-side fluid; removable for inspection.
NozzlesSA105, 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
Customized Services
We provide end-to-end services from concept design to final delivery:
  • Thermal and mechanical design based on process data
  • Optional special internal structures for improved efficiency
  • Auxiliary system integration including tube racks and instrumentation
  • On-site services: Installation guidance, commissioning support, and after-sales maintenance
