插管（stub-in）和翻邊（stub-end）的選用及工程應用
一、插(cha)管(guan)(guan)(guan)(guan)(guan)（stub-in）的(de)選用(yong)及工程應(ying)用(yong) 插(cha)管(guan)(guan)(guan)(guan)(guan)不(bu)是(shi)配管(guan)(guan)(guan)(guan)(guan)附件，其(qi)實是(shi)另(ling)一種接支管(guan)(guan)(guan)(guan)(guan)方法，插(cha)管(guan)(guan)(guan)(guan)(guan)可(ke)(ke)與主(zhu)(zhu)管(guan)(guan)(guan)(guan)(guan)口徑(jing)相(xiang)同或比主(zhu)(zhu)管(guan)(guan)(guan)(guan)(guan)口徑(jing)小(xiao)。這種方法經常使用(yong)，但其(qi)應(ying)力均(jun)集(ji)中在(zai)連(lian)接口，因(yin)此(ci)不(bu)適用(yong)于高溫或高壓(ya)場合。插(cha)管(guan)(guan)(guan)(guan)(guan)比三通(tong)便宜，也(ye)比三通(tong)少(shao)兩(liang)個(ge)焊縫。在(zai)支管(guan)(guan)(guan)(guan)(guan)的(de)相(xiang)鄰兩(liang)插(cha)管(guan)(guan)(guan)(guan)(guan)，距離(li)可(ke)(ke)由...
