Studded Finned Tube ASTM A106 Gr. B Carbon Steel Seamless
Tube for Steam Furnace
ASTM A106 Gr.B Carbon steel is a common material used in manufacturing studded finned tubes due to its good thermal conductivity and mechanical properties. It is suitable for a wide range of industrial applications where cost-effectiveness and corrosion resistance are important considerations.Studded fin tubes feature fins that are welded or resistance-welded to the outer surface of the base tube. These fins can be either solid or serrated and are typically made of carbon steel or stainless steel. The studded design provides additional surface area for heat transfer, improving the overall efficiency of the heat exchanger or boiler. Studded fin tubes are manufactured according to various international standards, including ASTM, ASME, and API.

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.
