Product Overview

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.

Material Properties & Chemical Composition

ASTM A335 Grade P9: This chromium-molybdenum alloy steel offers excellent high-temperature strength, corrosion resistance, and oxidation resistance, making it ideal for high-pressure and high-temperature environments.

Construction Features

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.
Serrated Fins: The fins are serrated and helically wound around the base tube, increasing surface area and enhancing heat transfer efficiency through boundary layer disruption.

Key Advantages

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
