摘　　要：一效~五效换热器管板为爆炸复合板16Mn(Ⅲ级锻件)+90Cu10Ni,管子为90Cu10Ni高通量管,管子管板焊接采用SMAW,结构为传统的端面焊接,管头伸出3mm如图1B,管子管板接头要求100%RT探伤。换热器管子/管板模块试验是施工前的焊工技能评定,参与焊接的每位焊工必须进行。The material of explosion cladding plates tube-sheet for the first ￣ fifth effect re-boiler is 16Mn (Ⅲ forging)+90Cu10Ni,The material of tubes is 90Cu10Ni(high flux tube, UOP offer) , SMAW is applied to tube-tubesheet fillets, joint configuration is the same as fig. 1B, the joints are required to 100% radiograph. It requires that every welder has to weld a mock-up before construction. Every attendee's ability should be confirmed.
