We should be s upported by pol itical a nd overall 弯头的分类方法 弯头的分类方法,按它的曲率半径来分,可分为长半径弯头和短半径弯头。长半径弯头指它的曲 率半径等于 1.5 倍的管子外径,即 R=1.5D。短半径弯头指它的曲率半径等于管子外径,即 R=D。 式中的 D 为弯头直径,R 为曲率半径。若按压力等级来分,大约有十七种,和美国的管子标准是相 同的,有:Sch5s、Sch10s、Sch10、Sch20、Sch30、Sch40s、STD、Sch40、Sch60、Sch80s、XS; Sch80、Sch100、Sch120、Sch140、Sch160、XXS,其中最常用的是 STD 和 XS 两种。
