Finned Tube ASTM A335 Grade P5 Alloy Steel Studded Pin Pipe For Heat Exchanger
Studded Pipe also called studded tubes, Nailhead Pipe or stud Pipe. Studded pipes are used as an alternative to finned tubes in heat exchangers mainly in the petrochemical industry where the surface is exposed to particular corrosion and aggression by gasses and vapors.
Studded pipe advantages:
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.

Advantages of Studded Tubes
1. As the pin rib of the studded tubes is a cantilever structure with a compact structure, the pin rib will vibrate under the impact of the air flow, making it difficult to accumulate soot.
2. due to the strong turbulent flushing of flue gas, the studded tubes heat exchange element has high heat transfer efficiency and strong self ash removal capability.
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.
