TP347H is a niobium-stabilized austenitic heat-resistant stainless steel, featuring excellent high-temperature creep resistance, outstanding intergranular corrosion resistance and steam oxidation resistance, and is suitable for long-term use in high-temperature and high-pressure working conditions.
ASTM A213 standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes.
Core Advantages of Stainless Steel HF Welded Finned Solid Tubes in Furnace Service
ASTM A312 TP347H After adding an adequate amount of niobium alloying elements, this material can effectively inhibit the precipitation of carbides, significantly enhance its resistance to intergranular corrosion, and be well-suited to the complex corrosive flue gas conditions inside industrial furnaces, thereby significantly extending its service life.
Using the high-frequency resistance welding process, the fins are firmly metallurgically bonded to the base tube. The welding strength is high, the bonding is tight, and there is no phenomenon of gap separation. This structure can stably withstand the thermal shock and vibrations inside the furnace, and there will be no problem of fin loosening or detachment.
The solid fin structure significantly increases the heat exchange area, greatly reduces the thermal resistance, accelerates the heat conduction and dissipation rate, effectively improves the overall heat exchange efficiency of the furnace equipment, and saves operating energy consumption.
It is manufactured strictly in accordance with the ASTM A213 standard for seamless steel pipes. The finished pipes have undergone standard solution heat treatment, with uniform internal structure, stable mechanical properties, and excellent resistance to thermal fatigue. They are suitable for working conditions where the furnace undergoes frequent temperature changes.
Fully applicable to the convective heating sections of industrial furnaces, radiation heat exchange components, waste heat recovery systems, and high-temperature flue gas cooling equipment. It can meet the stringent working conditions of various industrial furnaces, thermal power furnaces, and petrochemical heating furnaces.
Key Application
Thermal Power Plant Boilers:High-temperature superheaters, reheaters, platen superheaters and high-pressure heating surfaces for ultra-supercritical power generation units.
Industrial Heating Furnaces:Convection section heating components, radiation section heat exchange tubes and flue gas waste heat recovery systems in various industrial furnaces.
Petrochemical Industry:Cracking furnaces, hydrogenation furnaces, reforming furnaces and high-temperature heat exchangers used in oil refining and chemical production.
Waste Heat Recovery Equipment:High-temperature flue gas heat exchangers, waste heat boilers and energy-saving heat exchange facilities for industrial exhaust gas utilization.
