Shell & Tube, U-Tube & Floating Head Designs | Custom ASME Fabrication for Process Cooling & Heating
Engineered Heat Transfer for Critical Processes
Yuhong Group Co., Ltd. designs and manufactures reliable thermal equipment for industries worldwide. Our core offerings include shell & tube heat exchangers, pressure vessels, and air coolers, supported by a full inventory of precision components—tube bundles, U-bend tubes, finned tubes, and parts such as tubesheets, baffles, and heads—ensuring seamless integration with existing systems.
Performance-Driven Heat Exchangers
Our industrial heat exchangers are engineered to deliver consistent thermal performance under real-world operating conditions. Whether you need to cool lubricating oil, condense process vapors, or recover waste heat, we provide solutions tailored to your fluid properties, pressure limits, and space constraints. Every unit is built to ASME code standards, with design types selected based on your specific maintenance access and thermal expansion requirements.
Heat Exchanger Type Overview
How to Match Your Process Requirements

Technical Highlights: Design Details for Long-Term Efficiency
Impingement Plate Design: Installing an impingement plate at the inlet nozzle where flow rates are high or where solid particles are present effectively prevents erosion damage at the tube bundle inlet. This is one of the most easily overlooked details for extending heat exchanger lifespan.
Baffle Notch Direction: For horizontally placed heat exchangers, the baffle notches should alternate vertically rather than horizontally to prevent shell-side media from settling and fouling at the bottom, while ensuring better gas-liquid separation.
Tube Bundle Support Spacing: Determine the maximum unsupported span of the baffles based on fluid-induced vibration analysis, rather than blindly using standard spacing. This is especially important for gas or two-phase flow conditions, preventing fatigue fracture caused by tube bundle resonance.
Five Hidden Causes of Heat Exchanger Efficiency Decline
Even with correct design parameters, heat exchangers may gradually deviate from their performance specifications during operation. Here are some common but easily overlooked causes of performance degradation:
Tube Wall Scaling: Even a thin layer of scale or coke can create thermal resistance several times greater than the metal wall itself. Regular cleaning is the most direct way to restore efficiency.
Tube Bundle Inlet Erosion: Solid particles or droplets in high-speed fluids can gradually thin the tube ends, leading to leaks. Checking for "knife-edge" edges at the tube inlets is an early diagnostic method.
Damaged or Missing Sealing Strips: Damaged sealing strips can cause shell-side fluid to bypass the tube bundle, resulting in a sharp drop in heat transfer efficiency of over 20%.
Loose Baffles: Fluid vibration or corrosion can cause the baffle tube holes to enlarge, losing effective support for the tube bundle and exacerbating vibration and wear.
Aging Gaskets: Internal leaks caused by aging tube box gaskets or floating head gaskets can cause some fluid to short-circuit without heat exchange, resulting in abnormal outlet temperatures.
Customized Services and Engineering Support
Quick Replacement Service: Based on drawings or on-site measurements of the old heat exchanger, we can complete the reverse design and manufacturing of the tube bundle or the entire unit in a short time.
Performance Upgrades: While maintaining the original shell structure, heat exchange efficiency or throughput can be improved by optimizing tube type, finning, or changing baffle layout.
Full Lifecycle Support: Spare parts packages (gaskets, fasteners, sacrificial anodes), on-site maintenance guidance, and operational parameter optimization suggestions are provided.
Typical Application Scenarios
Refining and Petrochemical: Atmospheric and vacuum distillation tower top condensers, hydrotreating reactor feed and discharge heat exchangers, catalytic cracking slurry coolers.
HVAC and District Energy: Plate/shell-and-tube heat exchangers for heat exchange stations, evaporators for ice storage systems.
General Industry: Air compressor interstage coolers, injection molding machine mold temperature controllers, hydraulic station oil coolers.
