HF Welding Fin Tubes of Material ASME SA106 Gr. B Carbon Steel , Tubos Aletados
High frequency welding fin tubes are specialized tubes that are manufactured using a high frequency welding process. This technique involves using high-frequency electrical currents to heat the edges of the metal, allowing them to be fused together without the need for additional filler materials.
The general materials of base tubes and of fins about the HF welding finned tube are carbon steel, alloy, stainless steel, etc.The bare pipe is a carbon steel pipe SA106 Gr.B, which is cheap but will rust over time, but generally does not affect the use in conventional environments.
This page let's talk about ASME SA106 Gr. B carbon steel HF welding finned tubes with carbon steel fins.
Detailes of ASME SA106 Base Tubes
ASME SA106 This specification covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 1 ⁄ 8 to NPS 48 [DN 6 to DN 1200] (Note 2) inclusive, with nominal (average) wall thickness as given in ASME B36.10M.

Advantages of HFW Finned Tubes
1.Because of the high welding speed and strong self cooling effect, the heat affected zone is small and oxidation is not easy to occur. Therefore, the microstructure and properties of the weld are very good;
2.The heat exchange area is large, reduce heat transfer and metal flow;
3.Corrosion resistance, wear resistance, low contact thermal resistance, high stability, anti ash ability;
4.Reduce the installation space of the required heat transfer surface and at the same time, it has high reliability:
5.The pressure drop on the tube side is reduced and the operation cost is reduced;
6.The stiffness and seismic performance of steel pipe are improved.
