Rittling Finned Tube Boiler

ASTM A179 Rittling Finned Tube   Material   ASTM A179 covers seamless cold-drawn low-carbon steel tubes used in heat exchangers, condensers, and similar heat transfer equipment. When manufactured as Rittling finned tubes, a continuous metal fin is mechanically or integrally bonded to the tube surface to increase surface area, improving heat transfer efficiency in HVAC, refrigeration, and process cooling systems.   Specification   Standard ASTM A179 / ASME SA179 Manufacturing Process Seamless, cold drawn Tube OD 16-140mm Wall Thickness 2-10mm Fin Type KL,L,LL,H ,spiral slot,low,Stud pipes Fin Material CS,1100Al,1060Al ,11Cr,6063,SA213-TP304H,ASME SA515-70 and so on Fin Height 5-30mm Fin Pitch 3.5-40mm Fin Thickness  0.5-4.0mm Length 1-25m Delivery Condition Annealed, stress-relieved     Key Features   Enhanced Heat Transfer Efficiency – continuous fins maximize surface area for improved thermal performance.
