| Abstract: | The cooling system of pagoda roof is the most serious corrosion position in oil refinery. The carbonsteel and the high-alloy steel are easy to corrode . The project need a new metal material to replaces them This paper r introduces the welding characteristics of duplex stainless steel and tube to tube sheet welding process of condenser manufactured by SAF2507 of duplex stainless steel . and 316L steel plate. Different type of joint and different shielding gases are used in the welding test. Through metallographic analysis of the welded joint and the heat-affected zone., it can find the reasonable welding process. |
