ASME SA 213 Stainless Steel Finned Tubes

The heat exchange finned tube is the most used heat exchanger tube in the heat exchange of gas and liquid. It is to weld a fin to the common base tube to enhance heating, so as to achieve the fast heat transfer of heat exchanger through heat exchange finned tube. According to the type of materials, it is divided into single-metal finned tubes and bimetal finned tubes. World iron & steel is one of the leading finned steel pipe manufacturers, factory, seller, and exporter, suppliers, we supply stainless steel finned tube in grade 304 and 316 according to ASTM A213, they are helpful in the various condenser and exchanger applications.


There are four main types of finned tube structure:

  • Spiral wound fin tube

  • Bimetal aluminum rolling heat exchange finned tube

  • Copper pipe and aluminum sleeve sheet

  • Steel tube skewers


Fin tubes are mainly used in:

  • Condensers and evaporators, absorption chillers, oil coolers, and other heat exchangers in air-conditioning and refrigeration equipment.

  • Condensate and evaporator in thermal power stations and nuclear power station heat exchangers, and condensate and evaporator in ship exchangers.

  • Various heat exchangers in gas turbine units and all petrochemical air coolers, diesel coolers, secondary coolers and waste heat recovery systems driers and heaters used by the chemical industry.
