ASTM A312 TP304 HF Welding Fin Tubes With SS304 Fins , Tubos Aletados

High Frequency Welding Finned Tubes

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 resulting fin tubes typically have fins attached to their surface, which enhance their heat transfer capabilities.The general materials of base tubes and of fins about the HF welding finned tube are carbon steel, alloy, stainless steel, etc.

This page let's talk about ASTM A312 stainless steel TP304 HF welding finned tubes with TP304 fins.

Detailes of ASTM A312 Base Tubes

ASTM A312 This specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.

Mechanical Properties

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.Corrosion resistance, wear resistance, low contact thermal resistance, high stability, anti ash ability;

3.The heat exchange area is large;

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;
