ASME SA312 TP347H Stainless Steel Fin Tube is manufactured by applying stainless steel fin strips onto a seamless TP347H pipe, typically using high-frequency welding (HFW) or embedded finning techniques. It’s ideal for high-temperature heater applications requiring superior creep strength, oxidation resistance, and structural stability under thermal stress.

Superior High-Temperature Strength: TP347H performs well under creep conditions in high heat zones.
Excellent Weldability: Seamless tube and fin strip have stable austenitic structure ideal for HFW or TIG welding.
Resistance to Oxidation & Carburization: Both base and fins resist scale formation at elevated temperatures.
Stable Grain Structure: Niobium stabilizer in TP347H prevents intergranular corrosion and ensures long service life.
Low Thermal Stress Fatigue: Suitable for cyclic operations in furnaces and fired heaters.
