‌Steam fin tube radiator is a fin tube radiator that uses steam as a heat transfer medium. It achieves the purpose of heating through the circulation of steam, with high heat exchange efficiency and a wide range of applications.

Steam fin tube radiators are usually made of steel pipe welding, and the material is generally low carbon steel or carbon steel. The equipment is light in weight and has moderate performance. Its heating temperature can reach about 180℃, the heat dissipation area is large, suitable for various places, and it is wear-resistant, durable and has a long service life.

The heat transfer medium of the steam fin tube radiator is high-temperature steam, which heats the air by circulating in the heat pipe, thereby increasing the indoor temperature. This radiator is widely used in various fields such as industry, chemical industry, agriculture, etc., and can be processed into different models according to actual needs to meet various needs.

The heat source of the steam fin tube radiator can be solar energy, liquefied gas, natural gas, etc., which has the characteristics of energy saving and low carbon.

Steam Finned Tube Radiators: Technical Overview

1. Steam Fin Tube Radiator Manufacturing Process

Steam finned tube radiators are manufactured through precision engineering processes:

• Tube Preparation: Seamless carbon steel tubes (ASTM A179) are cut to required lengths
• Fin Attachment: Fins are attached via:
  • L-footing: For low-temperature applications (<200°C)
  • Embedded: High-pressure resistance (up to 25 bar)
  • G-footing: Corrosion-resistant variants
• Assembly: Tube bundles are assembled with headers using TIG welding
• Pressure Testing: Hydrostatic tested at 1.5x working pressure
• Surface Treatment: Hot-dip galvanizing or epoxy coating
