Seamless Alloy Finned Studded Tube ASTM A213 T9 for Heat Exchanger

• Excellent mechanical properties and resistance to oxidation and corrosion
• Withstands temperatures up to 650°C (1200°F) while maintaining structural integrity
• Chromium content provides superior oxidation resistance in high-temperature environments
• Resistant to sulfur-containing environments and other corrosive media
• High tensile strength and creep resistance for demanding applications
• Allows for thinner tube walls, improving heat transfer efficiency

Studded tubes are heat exchanger tubes featuring small welded studs or pins on their outer surface. These studs significantly increase surface area, enhancing heat transfer efficiency when exchanging heat between the tube and surrounding medium (gases or fluids).

Common materials include carbon steel for general applications, stainless steel for corrosive environments, and alloy steels (T9, T11, T12) for high-temperature, high-pressure applications.
