ASTM A213 covers seamless ferritic and austenitic alloy steel pipe for boilers, superheaters, and heat exchangers. It requires high-temperature performance and nondestructive testing.
TP347 offers high strength and creep resistance at high temperatures. Its excellent oxidation resistance makes it suitable for components exposed to continuous high-temperature environments. In addition to its excellent resistance to intergranular corrosion, it also exhibits good corrosion resistance against a wide range of organic and inorganic acids and alkalines.
Thus, TP347 is a proven and reliable choice for applications involving high temperatures, post-weld use, or temperatures susceptible to sensitization. It is commonly found in core high-temperature equipment in the power generation and petrochemical industries.

Applications
Due to its high-temperature strength and resistance to intergranular corrosion, TP347 seamless pipe is primarily used in the following demanding environments:
Power generation industry
Superheater and reheater tubes for power station boilers
High-pressure, high-temperature steam piping
Petrochemical Industry
Tubes and pipelines for catalytic cracking units, steam reformers, and ethylene cracking furnaces.
Heat exchangers handling corrosive media.
