Yuhong Group: Your Partner in Heat Transfer Solutions
Yuhong Group Co., Ltd. is a reliable manufacturer of industrial thermal equipment, specializing in shell & tube heat exchangers, pressure vessels, and air coolers. We supply high-quality replacement components including tube bundles, U-tubes, heat exchanger tubes, and critical parts for maintenance and retrofit projects.
This tube bundle is engineered as a direct, drop-in replacement for shell and tube heat exchangers operating in non-corrosive or mildly corrosive services. It features ASME SA179 seamless cold-drawn low-carbon steel tubes for efficient heat transfer, combined with a robust ASME SA266 Grade 2N forged carbon steel tubesheet.
Component Specifications & Material Details
Component
Material Standard / Grade
Key Characteristics & Function
Heat Exchanger Tubes
ASME SA179
Seamless, cold-drawn low-carbon steel; excellent thermal conductivity and smooth internal surface for minimal flow resistance.
Tubesheet
ASME SA266 Grade 2N (Forged)
Forged carbon steel; fine-grained structure provides high strength, toughness, and resistance to deformation under tube expansion loads.
Baffles
Typically ASME SA516 Gr. 70
Direct shell-side fluid for optimized flow distribution and enhanced heat transfer; supports tubes against vibration.
Tie Rods & Spacers
Carbon Steel (e.g., SA193 B7)
Maintain precise baffle spacing and overall bundle rigidity during operation.
Sealing Strips
Carbon Steel
Prevent fluid bypass around the bundle periphery, maximizing thermal efficiency.
Technical Highlights: Advantages of Forged Tube Sheets
Dense Microstructure: Forging process eliminates casting defects, ensuring metal flow lines are distributed along the tube sheet profile, significantly improving fatigue and impact resistance.
Excellent Machinability: Forged carbon steel exhibits better dimensional stability during drilling and grooving, ensuring bore accuracy and surface finish for reliable tube expansion/welding.
High Pressure Resistance: Forged tube sheets withstand higher tube-side pressures and tube bundle weight, making them suitable for large heat exchangers or high-pressure conditions.
ASME Compliance: Materials fully comply with ASME BPVC requirements with complete Material Test Reports (MTR) for global project compliance.
Core Advantages and Customization Services
Ready to Use: Manufactured strictly according to customer-provided drawings or existing parts dimensions for perfect match with original shell.
Flexible Tube Bundle Design: Available in straight or U-shaped tube configurations with various tube spacings, arrangements, and baffle spacings.
Reliable Tube End Connections: Precision expansion joints and optional sealing welding ensure long-term leak-free operation.
Comprehensive Quality Assurance: All critical components include Material Test Reports with rigorous manufacturing process inspection.
Optional Corrosion-Resistant Coatings: Epoxy coatings or plating available for enhanced durability in mildly corrosive environments.
Knowledge Module: Key Considerations for Tube Bundle Maintenance
Material Compatibility: New bundle materials should be compatible with original shell material in terms of thermal expansion coefficient and weldability.
Expansion Joint Process: Tube sheet borehole precision and surface condition directly affect expansion joint quality and reliability.
Vibration Analysis: Optimized baffle spacing and tube bundle support suppress vibration and prevent premature failure.
Power Industry: Generator air coolers, transformer oil cooling, turbine lubricating oil cooling
Chemical and Petrochemical: Process fluid heating/cooling, gas condensation, solvent recovery
HVAC: Chillers, heat pumps, district heating heat exchangers
Industrial Manufacturing: Air compressor aftercoolers, hydraulic oil cooling, process water cooling
