Key Advantages

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

Product Definition

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.

Applications

Petrochemical and Refining Industries - Processing high-temperature fluids and gases
Industrial Heating Systems - Thermal oil heaters and steam generators
Power Plants - Economizers, air preheaters, and superheaters
Marine and Offshore Applications - Heat exchangers for marine equipment
Waste Heat Recovery Systems - Boilers, furnaces, and exhaust systems
