Austenitic Structure: Provides excellent toughness and high-temperature strength.
Key Features Suitable For Heat Exchangers
The A213 TP347 tube plays a crucial role in heat exchangers,condensers, and boilers due to its material properties and design.
TP347 has high-temperature performance,excellent creep resistance (up to 800°C / 1472°F),can resistant to oxidation & scaling in steam environments
Common Applications in Power Plants
| Heat Exchangers in HRSG & Condensers in high-sulfur environments |
| Boiler & Superheater & Reheater Tubes (high-temperature/pressure environments) in coal-fired & nuclear plants |
| Chemical Processing Equipment (resistant to acids, chlorides, and sulfides) |
| Food, Pharmaceutical, and Marine Industries |
