一、不銹鋼三通是什么

不銹鋼三通為管(guan)(guan)件、管(guan)(guan)道連接件。用在主管(guan)(guan)道要分(fen)(fen)支(zhi)管(guan)(guan)處。不銹鋼三通有等徑(jing)和異徑(jing)之分(fen)(fen)，等徑(jing)三通的接管(guan)(guan)端(duan)部均為相(xiang)同(tong)(tong)的尺(chi)寸(cun)；異徑(jing)的三通的主管(guan)(guan)接管(guan)(guan)尺(chi)寸(cun)相(xiang)同(tong)(tong)，而支(zhi)管(guan)(guan)的接管(guan)(guan)尺(chi)寸(cun)小于主管(guan)(guan)的接管(guan)(guan)尺(chi)寸(cun)。

二、不銹鋼三通的原理

不銹鋼(gang)三(san)通(tong)(tong)是(shi)用(yong)于管(guan)(guan)(guan)(guan)道分(fen)支(zhi)處的(de)一(yi)種(zhong)(zhong)管(guan)(guan)(guan)(guan)件(jian)。對于采(cai)用(yong)無縫管(guan)(guan)(guan)(guan)制造三(san)通(tong)(tong)來講，通(tong)(tong)常(chang)所采(cai)用(yong)的(de)工藝(yi)有液(ye)壓(ya)(ya)(ya)脹形(xing)和(he)熱壓(ya)(ya)(ya)成(cheng)形(xing)兩(liang)種(zhong)(zhong)。不銹鋼(gang)三(san)通(tong)(tong)的(de)液(ye)壓(ya)(ya)(ya)脹形(xing)是(shi)通(tong)(tong)過(guo)金(jin)屬材料的(de)軸向補償脹出支(zhi)管(guan)(guan)(guan)(guan)的(de)一(yi)種(zhong)(zhong)成(cheng)形(xing)工藝(yi)。其過(guo)程是(shi)采(cai)用(yong)專用(yong)液(ye)壓(ya)(ya)(ya)機，將與三(san)通(tong)(tong)直徑相(xiang)等的(de)管(guan)(guan)(guan)(guan)坯(pi)(pi)內注入液(ye)體(ti)(ti)，通(tong)(tong)過(guo)液(ye)壓(ya)(ya)(ya)機的(de)兩(liang)個水平側缸同步對中運(yun)動擠壓(ya)(ya)(ya)管(guan)(guan)(guan)(guan)坯(pi)(pi)，管(guan)(guan)(guan)(guan)坯(pi)(pi)受擠壓(ya)(ya)(ya)后(hou)體(ti)(ti)積變小(xiao)，管(guan)(guan)(guan)(guan)坯(pi)(pi)內的(de)液(ye)體(ti)(ti)隨(sui)管(guan)(guan)(guan)(guan)坯(pi)(pi)體(ti)(ti)積變小(xiao)而壓(ya)(ya)(ya)力升(sheng)高，當達到不銹鋼(gang)三(san)通(tong)(tong)支(zhi)管(guan)(guan)(guan)(guan)脹出所需要的(de)壓(ya)(ya)(ya)力時(shi)，金(jin)屬材料在側缸和(he)管(guan)(guan)(guan)(guan)坯(pi)(pi)內液(ye)體(ti)(ti)壓(ya)(ya)(ya)力的(de)雙重作用(yong)下沿(yan)模具內腔流動而脹出支(zhi)管(guan)(guan)(guan)(guan)。

不(bu)銹(xiu)鋼三通的液壓脹(zhang)形工藝可一(yi)次成形，生產效率(lv)較高(gao)；不(bu)銹(xiu)鋼三通的主管及(ji)肩部壁厚(hou)均有增加。

三、不銹鋼三通的分類

因不銹鋼三通的液壓脹形工藝(yi)所需的設備噸位較大，國內主要用于小于DN400的標準壁(bi)厚不(bu)銹鋼(gang)三通的制造。其適用的成形材(cai)料為(wei)冷作硬(ying)化(hua)傾(qing)向(xiang)相(xiang)對較低(di)(di)的低(di)(di)碳鋼(gang)、低(di)(di)合(he)金鋼(gang)、不(bu)銹鋼(gang)，包括一些有色金屬材(cai)料，如(ru)銅、鋁、鈦等。
