三(san)通为管(guan)(guan)件、管(guan)(guan)道连接件。又叫管(guan)(guan)件三(san)通或者三(san)通管(guan)(guan)件，三(san)通接头(tou)，用在主管(guan)(guan)道要(yao)分支管(guan)(guan)处。

　　三(san)(san)通(tong)是(shi)具有三(san)(san)个(ge)(ge)(ge)(ge)口(kou)(kou)子(zi)，即一(yi)(yi)个(ge)(ge)(ge)(ge)进口(kou)(kou)，两(liang)个(ge)(ge)(ge)(ge)出口(kou)(kou)；或(huo)两(liang)个(ge)(ge)(ge)(ge)进口(kou)(kou)，一(yi)(yi)个(ge)(ge)(ge)(ge)出口(kou)(kou)的一(yi)(yi)种化工管件，有T形与Y形，有等径管口(kou)(kou)，也有异径管口(kou)(kou)，用(yong)于(yu)三(san)(san)条相同(tong)或(huo)不同(tong)管路汇集处。三(san)(san)通(tong)的主要作用(yong)是(shi)改变(bian)流体(ti)方向的。

　　不(bu)锈(xiu)(xiu)钢(gang)三通(tong)(tong)(tong)(tong)是用于管(guan)(guan)(guan)道分支(zhi)处的(de)一(yi)种(zhong)管(guan)(guan)(guan)件。对于采用无缝管(guan)(guan)(guan)制造三通(tong)(tong)(tong)(tong)来讲，目(mu)前通(tong)(tong)(tong)(tong)常所(suo)采用的(de)工艺(yi)有液(ye)压(ya)(ya)胀形(xing)和热压(ya)(ya)成形(xing)两种(zhong)。不(bu)锈(xiu)(xiu)钢(gang)三通(tong)(tong)(tong)(tong)的(de)液(ye)压(ya)(ya)胀形(xing)是通(tong)(tong)(tong)(tong)过(guo)金属材料的(de)轴向补偿(chang)胀出支(zhi)管(guan)(guan)(guan)的(de)一(yi)种(zhong)成形(xing)工艺(yi)。其(qi)过(guo)程是采用专用液(ye)压(ya)(ya)机，将与(yu)三通(tong)(tong)(tong)(tong)直径(jing)相等的(de)管(guan)(guan)(guan)坯(pi)(pi)内(nei)注(zhu)入(ru)液(ye)体，通(tong)(tong)(tong)(tong)过(guo)液(ye)压(ya)(ya)机的(de)两个水平侧缸同(tong)步对中运动挤(ji)压(ya)(ya)管(guan)(guan)(guan)坯(pi)(pi)，管(guan)(guan)(guan)坯(pi)(pi)受挤(ji)压(ya)(ya)后体积(ji)变(bian)小，管(guan)(guan)(guan)坯(pi)(pi)内(nei)的(de)液(ye)体随管(guan)(guan)(guan)坯(pi)(pi)体积(ji)变(bian)小而(er)压(ya)(ya)力升高，当(dang)达到不(bu)锈(xiu)(xiu)钢(gang)三通(tong)(tong)(tong)(tong)支(zhi)管(guan)(guan)(guan)胀出所(suo)需要的(de)压(ya)(ya)力时，金属材料在(zai)侧缸和管(guan)(guan)(guan)坯(pi)(pi)内(nei)液(ye)体压(ya)(ya)力的(de)双(shuang)重作用下沿(yan)模(mo)具内(nei)腔流动而(er)胀出支(zhi)管(guan)(guan)(guan)
