摘要
一效～五效换热器管板为爆炸复合板16MnⅢ+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3 mm,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,要求对参与焊接的每位焊工进行此项评定.
Material of explosion cladding plates tube - sheet for the first - fifth effect re - boiler were 16Mn（ Ⅲ forging） ＋ 90Cu10Ni,material of tubes were 90Cu10Ni（high flux tube, UOP offer） , SMAW was applied to tube-tubesheet fillets,the joints were required to 100% radiograph. Required per- attendee to weld mock up and welder＇s ability should be confirmed.
