ASTM A213 TP347H Serrated Finned Tube is an ultra-high-temperature heat transfer solution engineered for critical creep-resistance applications. It features a seamless niobium-stabilized austenitic stainless steel base tube (ASME SA213 TP347H) with helically wound serrated fins resistance-welded to the surface. This design delivers exceptional oxidation resistance up to 900°C (1,652°F) and prevents carbide precipitation in continuous service, making it the premier choice for superheaters, reformers, and waste heat boilers in aggressive environments.

· Power Plant Boilers: Superheaters/reheaters in 600°C+ USC coal units.
· Petrochemical: Ethylene cracker transfer line exchangers.
· Waste-to-Energy: Superheaters for corrosive waste incinerators.
· Chemical Processing: Hydroprocessing furnace convection banks.
· Steel Mills: Recuperators for coke oven gas.
4. Why Choose ASTM A370 TP347H
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:
· Zero Sensitization: Nb stabilization eliminates post-weld heat treatment.
· Ash Erosion Defense: Serrations reduce fouling by 45% (EPRI Field Data).
· Life Extension: 3x longer service than TP321H in 700°C flue gas.
· Custom Engineered: No-fin zones, fin pitch, and bevels per client drawings.
