Steel Elements Standard options feature 1 1/ 4 (32 mm) steel tube with 52 steel fins per foot (171 per meter). Elements available in copper-aluminum or steel. Elements are efficient and long lasting. Element tubes mechanically expanded into fin collars. Fin collars provide even and positive spacing for even air distribution.
Laser Welding Of Finned Tubes Made Of Austenitic Steels
PDF, This paper describes the technology of welding of finned tubes made of the X5CrNi1810 (1.4301) austenitic steel, developed at Energoinstal SA, allowing one to get high quality joints that air preheating fin tube steels
Air preheater - Wikipedia
Tubular preheaters consist of straight tube bundles which pass through the outlet ducting of the boiler and open at each end outside of the ducting. Inside the ducting, the hot furnace gases pass around the preheater tubes, transferring heat from the exhaust gas to the air inside the preheater.
Welding-distortion and warping control: understanding and ...
The general approach would be to reduce the causes of Welding-distortion by providing suitable pre-heating, if possible, so that there will be less expansion difference, between material at weld temperature and surrounding structure. The actual determination of residual stresses after any of the above methods is done by specialized technologies.

Air-cooled heat exchanger fins are commonly made from aluminum or copper or can be fabricated from stainless or carbon steel & range in size from 5/8 in. to 1 in. OD. Air-cooled heat exchangers are suitable for heating & air conditioning, process heating & cooling, air-cooled process equipment, energy & solvent recovery, combustion air air preheating fin tube steels
Steam Coils and Steam Air Heaters Delta
Finned tubes are almost always used in steam coil applications. A steam coil is used to heat air when steam is available. This type of coil makes use of the latent heat that is released by the steam when it condenses so it is a very effective way of heating air.
Medium-high finned tubes - Wieland Thermal Solutions
NEW: Medium-high finned tubes made of stainless steel. GEWA-D medium-high finned tubes made of stainless steel can be used for condensing boilers or domestic hot water applications. Due to the enlarged outside heat transfer surface area the required tube length can be reduced and thus costly material can be saved.
