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 to 10 bare
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
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.
The finned tube is a heat transfer component that increases the heat exchange area by helically wound fins on the base tube. Fins and base tube forming a strong mechanical contact,that greatly improving the heat transfer efficiency.
It widely application to Economizer,Boilers, Heat ex-changers,tube bundles,Radiators, air coolers, air preheater etc.
