　　某公司雙金屬機械複合管工藝的研究結果如下： 

　　（1）為了獲得最佳的複合效果
，外基管材質級別要盡可能高，而內襯管材質也應采用剛度匹配的材料。在內襯管
、外基管的材料既定的情況下，複合過程采用的水壓越大
，複合管獲得的剩餘彈性勢能越多
，複合效果越好。 

　　（2）複fu合he管guan水shui壓ya膨peng脹zhang試shi驗yan過guo程cheng中zhong，密mi封feng水shui壓ya力li與yu時shi間jian關guan係xi曲qu線xian是shi指zhi導dao複fu合he作zuo業ye的de重zhong要yao依yi據ju，當dang外wai基ji管guan處chu於yu彈dan性xing變bian形xing向xiang塑su性xing變bian形xing階jie段duan過guo渡du的de拐guai點dian時shi，複fu合he管guan進jin入ru彈dan性xing變bian形xing極ji限xian位wei置zhi，此ci時shi對dui複fu合he管guan內nei腔qiang液ye體ti的de壓ya力li進jin行xing卸xie載zai
