Product Description
Carbon Steel Heat Exchanger Tube Bundle
ASME SA179 Tubes & SA105 Tubesheet | Reliable Replacement Core
Yuhong Group Co., Ltd. specializes in the supply of robust thermal equipment and precision-engineered parts. We provide shell & tube heat exchangers, pressure vessels, and a full range of compatible replacement assemblies, including tube bundles, U-tubes, bare and finned tubes, along with essential spare parts like tubesheets, baffles, and heads for maintenance and upgrades.
Cost-Effective ASME Tube Bundle
This tube bundle serves as a direct, drop-in replacement for worn or degraded cores in shell and tube heat exchangers. It combines ASME SA179 seamless cold-drawn low-carbon steel tubes for efficient heat transfer with a forged carbon steel ASME SA105 tubesheet, delivering a reliable and economical solution for non-corrosive or mildly corrosive services such as water, oil, or gas systems.
Component Breakdown & Specifications
| Core Component | Material Standard | Key Role & Characteristic |
|---|---|---|
| Heat Exchanger Tubes | ASME SA179 | Seamless, low-carbon steel tubes ensuring smooth flow and effective heat conduction. |
| Tubesheet | ASME SA105 | Forged carbon steel plate offering excellent strength and machinability for secure tube anchoring. |
| Baffles | Typically ASME SA516 Gr. 70 | Directs shell-side fluid across the tube bundle to enhance thermal efficiency and provide structural support. |
| Tie Rods & Spacers | Carbon Steel (e.g., SA193 B7) | Maintains precise baffle spacing and overall bundle integrity during operation. |
| Side Channel / Header | ASME SA105 or SA350 LF2 | Forged carbon steel component for tube-side fluid distribution and collection. |
Tube Sheet Material Selection - Why SA105 is Commonly Used
SA105 is a forged carbon steel material widely used in pressure vessels and heat exchanger components. Its advantages as a tube sheet material include:
- Excellent Mechanical Properties: The forging process gives it a dense metallic structure, providing good strength, toughness, and fatigue resistance, enabling it to withstand the stress of tube expansion or welding and pressure fluctuations during operation.
- Excellent Machinability: Compared to cast materials, SA105 is easier to drill, mill, and turn, allowing for high-precision machining of tube holes and ensuring a tight and airtight connection between the tubes and the tube sheet.
- Economy and Wide Applicability: As a standardized forged material, SA105 achieves a good balance between cost and performance, making it a reliable and economical choice for tube sheets operating in water, oil, steam, and other non-corrosive media conditions.
Core Advantages and Value
- Ready-to-install, reducing downtime: Manufactured according to original dimensions for quick installation, minimizing production losses caused by equipment shutdowns.
- Optimized thermohydraulic performance: Tube bundle layout and baffle design can be optimized based on the original equipment or specific working conditions, ensuring efficient heat transfer and reasonable pressure drop.
- Flexible customization services: We can customize the number of tubes, arrangement pattern, pitch, length of the tube bundle and baffle design according to the drawings or samples provided.
- Strict quality control: Material Test Certificates (MTC) are provided for key components. Critical processes such as tube end expansion/welding comply with strict technical specifications to ensure reliability during long-term operation.
Typical Application Fields
- Heating, Ventilation and Air Conditioning (HVAC) systems: Chillers, heat recovery units
- Industrial cooling systems: Lubricating oil coolers, transformer oil coolers, air compressor aftercoolers
- General industrial processes: Process water heating/cooling, low-pressure steam condensation
- Power industry: Various auxiliary coolers
