1. What is ASTM A376 TP347H Alloy Steel HFW Solid Finned Tube?
The ASTM A376 TP347H Alloy Steel HFW Solid Finned Tube is a premium heat transfer solution engineered for extreme high-temperature and corrosive environments. It combines a seamless niobium-stabilized austenitic stainless steel base tube (ASTM A376 TP347H) with helically wound solid carbon steel fins bonded via high-frequency welding (HFW). This robust design delivers unmatched resistance to oxidation, sulfidation, and creep deformation up to 900°C (1,652°F), making it ideal for superheaters, reformers, and waste heat boilers in power plants and refineries. The Nb stabilization prevents carbide precipitation, ensuring long-term performance in cyclic thermal services.

3. Key Applications in Refineries & Power
· Fluid Catalytic Cracking Units (FCCU): Waste heat boilers exposed to 650°C+ flue gas with sulfur compounds
· Hydroprocessing Heaters: Charge heaters in hydrotreaters/hydrocrackers resisting H₂S + naphthenic acid
· HRSGs (Heat Recovery Steam Generators): Evaporator/superheater sections requiring creep resistance
· Sulfur Recovery Units (SRU): Tail gas incinerators combating sulfidation attack
· Reformer Furnaces: Convection sections with coking tendencies at 700°C+
4.Why Choose ASTM A376 TP347H Alloy Steel HFW Solid Finned 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.
