Product | Fin Tubes or Finned Tube |
Type | High Frequency Welding Finned Tubes |
Standard | ASTM A312 |
Material | Stainless Steel TP304 Base Tubes and Fins |
Use | Heat Exchanger / Boiler / Furnaces / Condensers / Evaporators, etc |
Packing | Ply-wooden Case With Iron Frame |
High frequency welding fin tubes are specialized tubes manufactured using high-frequency electrical currents to heat and fuse metal edges without additional filler materials. The resulting fin tubes feature surface fins that enhance heat transfer capabilities. Materials for base tubes and fins include carbon steel, alloy, and stainless steel.
ASTM A312 specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe for high-temperature and general corrosive service.
