ASTM A355 P9 Alloys Welding Serrated Finned Tube For Waste Heat Boiler

Welding fin tubes, specifically the helical serrated type with a base tube made of ASTM A335 Grade P9, are advanced heat transfer components designed for high-efficiency applications in demanding environments. This configuration combines the mechanical strength and heat resistance of the base tube with the enhanced heat transfer properties provided by the serrated fins.

ASTM A335 Grade P9: This is a chromium-molybdenum alloy steel known for its excellent high-temperature strength, corrosion resistance, and resistance to oxidation. It is commonly used in high-pressure and high-temperature environments.

Serrated Fins: The fins are serrated and helically wound around the base tube, increasing the surface area and enhancing the heat transfer efficiency. The serrations disrupt boundary layers and promote turbulent flow, improving overall heat exchange.

• Welded Fin Attachment: The fins are welded to the base tube, ensuring a robust and durable bond that can withstand thermal cycling and mechanical stresses.
• Helical Serration: The helical arrangement of the fins provides uniform heat distribution and promotes efficient heat transfer.

• High Thermal Efficiency: Enhanced heat transfer through increased surface area and turbulent flow promotion
• Durability and Longevity: Excellent high-temperature performance and corrosion resistance
• Versatility: Suitable for various industrial applications including power generation and petrochemical processing
