Large Diameter Seamless Steel Pipe High Frequency Welded Finned Pipe/Tube


Large diameter finned pipes are essentially large diameter steel tubes equipped with fins. These fins increase the surface area of the pipe, thereby significantly enhancing its heat dissipation capabilities. The primary purpose of these pipes is to serve as the foundation for radiators that require excellent heat dissipation performance. By increasing the heat exchange area, these pipes improve efficiency and reduce the fluid resistance within the pipeline, leading to faster fluid flow and superior heat dissipation.

Materials and Standards


The base pipe material for large diameter finned pipes varies depending on the application and environmental conditions. Common materials include:

  • Carbon Steel: ASTM A106 Gr. B
  • Alloy Steel: ASTM A335 P22
  • Stainless Steel: ASTM A312 TP304/316
  • Nickel Base Steel: ASTM B163/B705

These materials are chosen based on their ability to withstand high temperatures and corrosive environments, making them suitable for use in power plants, refineries, and chemical industries.

Types of Large Diameter Finned Pipes


There are several types of large diameter finned pipes, each designed to meet specific industrial needs:

  • High Frequency Welding Solid Fin Pipe
  • High Frequency Welding Serrated Fin Pipe

These different types cater to varying heat dissipation requirements and are selected based on the specific needs of the application.
