ASTM A213 T22 Serrated Fin Tube is a high-efficiency heat transfer solution engineered for extreme ash-laden and high-temperature environments. It features a seamless chromium-molybdenum alloy steel base tube (ASTM A213 T22, UNS K21590) with helically wound serrated carbon steel fins bonded via high-frequency welding (HFW). The serrated fin edges disrupt boundary layers, enhancing heat transfer by 35% while reducing ash fouling by 50% compared to smooth fins. Ideal for boiler superheaters, reformers, and waste heat recovery systems operating up to 590°C (1,094°F).

● Coal-Fired Boilers: Superheaters in 550°C+ units (resists >60g/Nm³ fly ash).
● Waste Incinerators: Convection sections for municipal solid waste (MSW) plants.
● Refinery Heaters: Vacuum residue upgrading units (sulfidation resistance per NACE RP0472).
● Biomass Energy: High-alkali flue gas economizers.
● Cement Plants: Preheater exhaust gas recovery.
4.Why choose ASTM A213 T22 Studded Fin Tube:
A:Company Competitiveness:
Yuhong Holding Group has more than 35 years experience for steel pipe and tube , fin tube , main application for Petrochemical , Oil refinary, Furnace, heating, boiler, heat exchanger, air cooler,.., till now YUHONG brand products already exported more than 85 countries, which like UK, ITALY, SPAIN , USA, MEXICO , COLOMBIA , BRAZIL, SAUDI ARANBIA , OMAN, QATAR, U.A.E, KOREA, ...., YUHONG brand already won good reputation in the market.
B:Product Competitiveness:
● Anti-Fouling Design: 50% lower ash buildup vs. smooth fins (EPRI AC-7891).
● 8-Year Lifespan: Withstands thermal cycling per ASME Sec. I.
● Cost Saving: 40% lower cost vs. TP347H finned tubes.
● Rapid Delivery: 80+ standard sizes (OD 25–152mm) in stock.
