Stud Finned Tube ASTM A213 T9 Alloy Steel Seamless Tube with Studded Fins
Alloy steel such as A213 T9 offers good strength, corrosion resistance, and high temperature performance, making it suitable for demanding environments. other common alloy steels like T5. T11, T22, T91, T91... are also good choice as base tube of finned tube. The addition of elements such as chromium and molybdenum enhances the properties of the steel, making it durable and reliable for industrial applications.
Studded Fin Tube is manufactured by Electric Resistance Welding of Studs on the Bare tubes. The design of studded fin tubes allows for greater surface area contact between the fluid and the tube, resulting in improved heat transfer rates, minimizing the buildup of deposits on the surface and ultimately more cost-effective operation. That's why they are commonly used in various industries such as petrochemical, oil and gas, power generation, HVAC, and chemical processing to efficiently transfer heat between fluids or gases.

Studded pipe advantages:
Because of their relatively thicker Cross-section as compared to fins, Studded pipe is one of the mechanically Strongest extended-surfaces Available. Although strength may not be a consideration for heat Transfer performance, it may be important when the application requires the extended surface to carry the weight of the tube at supports, or where severe mechanical abuse is expected in service or during cleaning.
Application
The mainly applications for studded tubes is the process heat recovery of the petrochemical industry, in areas of convection ovens, vacuum generators for chemical processing, specially used in petroleum applications. Studded pipes high resistance in the harsh environments, such as sections of Sulfuric Acid atmospheres, makes it very useful for the industries mentioned.
