Product Description

ASTM A335 P22 Serrated Fin Tube

I. Product Overview

ASTM A335 P22 serrated fin tubes are manufactured from P22 chromium-molybdenum alloy steel, a material specifically designed for high-temperature and high-pressure service. With a nominal composition of 2.25% chromium and 1% molybdenum, this grade provides excellent resistance to oxidation, creep, and sulfur attack at elevated temperatures. The tube utilizes a seamless base pipe combined with helically wound, serrated (notched) fins that are securely attached through high-frequency welding or an embedded process. The serrated fin design significantly increases turbulence and disrupts boundary layers, enhancing heat transfer efficiency compared to plain fins. This construction maintains robust pressure integrity while offering superior thermal performance in demanding environments. Suitable for high-temperature heat exchangers, boilers, heaters, and other critical pressure equipment, it can be supplied in custom dimensions and fin configurations to meet specific project requirements.

Cost	Medium-High	Lowest	Medium-High

V. Key Applications

● Power Generation Boilers: Superheater and reheater tubes, economizer sections, and high-pressure steam lines in coal-fired and thermal power plants.

● Petrochemical & Refinery Heaters: Process heater coils, convection and radiant sections in crude, vacuum, and reformer heaters.

● Heat Recovery Steam Generators (HRSG): Evaporator and superheater coils in gas turbine co mbined-cycle units.

● High-Temperature Heat Exchangers: Waste heat recovery units, air preheaters, and process gas coolers in chemical and metallurgical industries.

● Industrial Boilers & Steam Systems: High-pressure steam coils, boiler bank tubes, and steam distribution piping in pulp/paper, textile, and food processing plants.

The 13Cr pins add some cost, but for sour service in furnaces, it's worth it. Already seeing longer run times between turnarounds compared to before.

Good strength, handles the pressure, no corrosion issues so far. We're running treated water, so no complaints.

Really good quality, the ASME SA249 standard is the real deal. I was worried about the fins getting crushed during the long trip, but the packaging was top-notch—not a single one was bent.
