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.
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
General industrial processes: Process water heating/cooling, low-pressure steam condensation
Power industry: Various auxiliary coolers
