插管(stub-in)和翻邊(stub-end)的選用及工程應用
一、插(cha)管(guan)(guan)(stub-in)的選用(yong)(yong)及工程應用(yong)(yong) 插(cha)管(guan)(guan)不(bu)是配管(guan)(guan)附(fu)件,其(qi)實是另一種接支管(guan)(guan)方法(fa),插(cha)管(guan)(guan)可(ke)與(yu)主管(guan)(guan)口(kou)徑相同或比主管(guan)(guan)口(kou)徑小。這種方法(fa)經常(chang)使用(yong)(yong),但其(qi)應力(li)均集中在連接口(kou),因(yin)此不(bu)適用(yong)(yong)于(yu)高溫或高壓場(chang)合(he)。插(cha)管(guan)(guan)比三通便宜(yi),也比三通少兩個(ge)焊縫。在支管(guan)(guan)的相鄰兩插(cha)管(guan)(guan),距離(li)可(ke)由...
