ASTM A312 TP304 HFW Fin Tube Fin Material Of 11-13 Cr
The ASTM A312 TP304 is a standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes. It is commonly used in high-temperature and corrosive environments.
HFW (High-Frequency Welding) is a welding method used to join the pipes. It involves the use of high-frequency electrical currents to generate heat and create a weld.
Fin tubes are used in heat exchangers and boilers to increase the heat transfer efficiency. The fin material of 11-13 Cr refers to a fin material made from stainless steel with a chromium content of 11-13%. This type of material provides good corrosion resistance and high-temperature strength, making it suitable for applications in corrosive and high-temperature environments.
