ASTM A335 P11 P22 P9 P91 Alloy Steel Studded Fin Tube For Heat Exchangers

ASTM A335 P11 P22 P9 P91 Alloy Steel Studded Fin Tube For Heat Exchangers

Studded Fin Tube is made by electrical resistance welding specially formed studs(round pins) in rows around the tube. The Studded fin tubes are also named pin fin tube. Studded tubes have a very high heat transfer efficiency. The heat exchange efficiency is equivalent to 2-3 times that of the bare tube. Studded fin tubes are generally used in furnaces and boilers of which the surface is exposed to corrosive environment. It can also increase efficiency in the process of heat recovery and direct flame hostile atmospheres. Studded fin tubes are ideal for processes applications where dirty fuels are used and harsh environments. They can be more easily cleaned especially for operating cases with dirty flue gas produced by burning heavy oil, diesel.
