Tube à ailettes à goujons

Stud fin tube is made by electrical Resistance welding specially formed Studs(Round pins ) in rows around the tube. The Studs can be supplied in a variety of Sizes and shapes. Also named pin fin tube.Stud tube have a very high heat transfer efficiency.The heat exchange efficiency is equivalent to 2-3 times that of the bare pipe. To increase the surface heat transfer coefficient of flue gas to the furnace tube.Reduce the amount of bare pipes used in these processes. (Heat transfer surface of one studded pipe is equivalent to surface of 4 À 10 bare pipes).

Studded tubes are generally used in furnaces and boilers where the surface is exposed to a very corrosive environment and where very dirty gas streams require frequent or aggressive cleaning.

Increase efficiency in the process of heat recovery and direct flame hostile atmospheres.

Studded Pipe’s ideal for processes applications where dirty fuels are used and harsh environments in terms of temperature and / or corrosion.Easier cleaning especially for operating cases with very dirty flue gas produced by burning heavy oil, diesel or residual oil.

Its high resistance to harsh environments, such as sections of Sulfuric Acid atmospheres, makes it very useful for the industries mentioned.

Properties of Studded Fin Tubes/Studded Fin Pipe:-

1. Processus de fabrication:- Electric Resistance Welding

2. Fin To Tube Bond:- Excellent

3. Heat Transfer Efficiency:- Excellent

4. Mechanical Resistance:- Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)

5. Corrosion Protection:- Gives excellent corrosion protection to the base tube since it entirely covers the base tube (except bare ends).

6. Temperature Range:- Depending on Properties of material of Fin (Stud) and Pipe
