ASTM A312 TP304 HF Welding Fin Tubes With SS304 Fins, 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 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 discusses ASTM A312 stainless steel TP304 HF welding finned tubes with TP304 fins.
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.
