Product Overview

ASTM A335 P22 Helical Solid Finned Tube is a high-performance heat exchanger tube manufactured from seamless ferritic alloy steel. The helical solid fins on its exterior surface significantly increase surface area for enhanced heat transfer efficiency, making it ideal for power generation, petrochemical, and chemical processing applications.

Key Features and Benefits

Enhanced Heat Transfer: Helical fins increase surface area for superior thermal performance
Compact Design: Achieves higher heat transfer rates without increasing exchanger size
Durable Construction: Seamless ferritic alloy steel withstands high-temperature and high-pressure conditions
Corrosion Resistance: Excellent resistance to wear and corrosion in demanding environments
