Product Description
ASME SA179 Carbon Steel Tube Bundle with SA266 Gr.2N Forged Tubesheet
Precision replacement core for shell and tube heat exchangers designed for optimal performance and reliability.
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.
Product Overview: Durable Carbon Steel Tube Bundle
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.
Typical Application Areas
- Oil Refining: Crude oil/product heat exchange, tower top condenser, lubricating oil cooling
- 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
