چکیده مقاله
Spiral finned tubes used a HRSG is the core facility of a combined cycle thermal power plant that recycles thermal energy from a gas turbine and creates high temperature and high pressure gas Serrated finned tubes and solid finned tubes are two types of spiral finned tubes used HF technology Solid and serrated fins are widely used solutions for improving heat transfer in fired heaters The important fact that designers or engineers often overlook while selecting the fins is that serrated fins can provide larger surface area and significantly higher fin efficiency compared with solid fins Carbon steel and alloy steel tube according to ASTM A192 and ASTM A213 As well as carbon steel and alloy steel coil strips according to ASTM A1008 and ASTM A240 TP409 International standard for tests of high frequency resistance welded fins according ASME and ASTM used for metallography fusion weld ,tensile strength, hardness This paper presents the microstructures welding of industrial fin tube boiler, with particular emphasis on high frequency resistance welded HFRW finned tubes
