紫銅管件標準和漏水原因

紫銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)標(biao)(biao)(biao)準(zhun)和(he)漏水(shui)原因(yin)： 　　1、材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)(zhi)上(shang)(shang)：美(mei)標(biao)(biao)(biao)及(ji)歐標(biao)(biao)(biao)均要(yao)(yao)求脫氧磷銅(tong)(tong)(tong)(tong)，具有(you)生產(chan)(chan)成(cheng)(cheng)本(ben)(ben)高(gao)但焊(han)(han)接(jie)性(xing)能(neng)好(hao)，更耐腐蝕，更高(gao)強度(du)等優點(dian)。但由于(yu)(yu)技術及(ji)成(cheng)(cheng)本(ben)(ben)問(wen)(wen)題(ti)，國內(nei)絕大(da)多數均為T2或(huo)T3銅(tong)(tong)(tong)(tong)，同時對(dui)于(yu)(yu)銅(tong)(tong)(tong)(tong)合(he)(he)金中鋅的(de)(de)(de)(de)(de)流失問(wen)(wen)題(ti)亦沒有(you)廠家(jia)(jia)有(you)能(neng)力解(jie)決。 　　2、配合(he)(he)公(gong)差上(shang)(shang)：國內(nei)的(de)(de)(de)(de)(de)標(biao)(biao)(biao)準(zhun)本(ben)(ben)身就過(guo)于(yu)(yu)寬松，配合(he)(he)間(jian)隙(xi)zui小甚至出(chu)現負值，意味無法將銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)插(cha)入管(guan)(guan)(guan)件(jian)(jian)(jian)內(nei);zui大(da)超過(guo)2.5mm，超過(guo)美(mei)標(biao)(biao)(biao)的(de)(de)(de)(de)(de)10倍(bei)、歐標(biao)(biao)(biao)的(de)(de)(de)(de)(de)5倍(bei)。普通精度(du)級(ji)的(de)(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)與管(guan)(guan)(guan)件(jian)(jian)(jian)配合(he)(he)公(gong)差遠遠不能(neng)滿足釬焊(han)(han)的(de)(de)(de)(de)(de)技術要(yao)(yao)求(≤0.25mm)。焊(han)(han)口(kou)(kou)的(de)(de)(de)(de)(de)整體(ti)性(xing)與穩定性(xing)很差，存(cun)在(zai)(zai)(zai)漏水(shui)的(de)(de)(de)(de)(de)隱患也就不難理解(jie)。 　　3、焊(han)(han)接(jie)工(gong)藝上(shang)(shang)：過(guo)大(da)的(de)(de)(de)(de)(de)配合(he)(he)間(jian)隙(xi)導致工(gong)人無法正(zheng)確采(cai)用(yong)釬焊(han)(han)工(gong)藝，而改用(yong)流動性(xing)差的(de)(de)(de)(de)(de)劣質(zhi)(zhi)(zhi)(zhi)(zhi)焊(han)(han)條，采(cai)用(yong)堆焊(han)(han)封住焊(han)(han)口(kou)(kou)，這(zhe)種焊(han)(han)口(kou)(kou)在(zai)(zai)(zai)水(shui)壓(ya)波動及(ji)熱脹冷縮容易出(chu)現漏水(shui)。 　　銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)標(biao)(biao)(biao)準(zhun)的(de)(de)(de)(de)(de)應用(yong)： 　　1、國標(biao)(biao)(biao)的(de)(de)(de)(de)(de)應用(yong)面(mian)較(jiao)窄、大(da)多數廠家(jia)(jia)仍按歐標(biao)(biao)(biao)或(huo)美(mei)標(biao)(biao)(biao)體(ti)系(xi)(xi)生產(chan)(chan)，便于(yu)(yu)市場(chang)配套(tao)。 　　2、因(yin)美(mei)標(biao)(biao)(biao)體(ti)系(xi)(xi)要(yao)(yao)求公(gong)差配合(he)(he)zui高(gao)，生產(chan)(chan)成(cheng)(cheng)本(ben)(ben)也zui高(gao)，故市場(chang)可(ke)(ke)供貨源(yuan)不多 　　3、國內(nei)的(de)(de)(de)(de)(de)所謂歐標(biao)(biao)(biao)管(guan)(guan)(guan)件(jian)(jian)(jian)實(shi)際上(shang)(shang)并未100%達到(dao)標(biao)(biao)(biao)準(zhun)的(de)(de)(de)(de)(de)要(yao)(yao)求，主要(yao)(yao)體(ti)現在(zai)(zai)(zai)材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)(zhi)上(shang)(shang)與公(gong)差配合(he)(he)上(shang)(shang)。 　　4、因(yin)未嚴格執行同一(yi)標(biao)(biao)(biao)準(zhun)體(ti)系(xi)(xi)，國產(chan)(chan)銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)及(ji)管(guan)(guan)(guan)件(jian)(jian)(jian)在(zai)(zai)(zai)實(shi)際應用(yong)中往往存(cun)在(zai)(zai)(zai)質(zhi)(zhi)(zhi)(zhi)(zhi)量隱患，問(wen)(wen)題(ti)集中在(zai)(zai)(zai)焊(han)(han)口(kou)(kou)質(zhi)(zhi)(zhi)(zhi)(zhi)量的(de)(de)(de)(de)(de)可(ke)(ke)靠性(xing)與穩定性(xing)方面(mian)。 　　銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)正(zheng)確選購： 　　1、分辨銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)優劣我們可(ke)(ke)以先觀察一(yi)下銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)外(wai)面(mian)的(de)(de)(de)(de)(de)表面(mian)，可(ke)(ke)以用(yong)一(yi)些(xie)比(bi)(bi)(bi)較(jiao)尖(jian)的(de)(de)(de)(de)(de)東西刮一(yi)下，要(yao)(yao)是銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)質(zhi)(zhi)(zhi)(zhi)(zhi)量比(bi)(bi)(bi)較(jiao)好(hao)的(de)(de)(de)(de)(de)話(hua)，就會有(you)一(yi)條深線(xian)產(chan)(chan)生，因(yin)為好(hao)的(de)(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)是用(yong)比(bi)(bi)(bi)純的(de)(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)生產(chan)(chan)出(chu)來的(de)(de)(de)(de)(de)，銅(tong)(tong)(tong)(tong)的(de)(de)(de)(de)(de)延伸性(xing)非(fei)常(chang)的(de)(de)(de)(de)(de)好(hao)。所以這(zhe)種比(bi)(bi)(bi)較(jiao)好(hao)的(de)(de)(de)(de)(de)材(cai)(cai)料不打(da)分是用(yong)在(zai)(zai)(zai)軍工(gong)業(ye)生產(chan)(chan)或(huo)者(zhe)是一(yi)些(xie)比(bi)(bi)(bi)較(jiao)特別(bie)(bie)的(de)(de)(de)(de)(de)行業(ye)當中。 　　2、我們還可(ke)(ke)以在(zai)(zai)(zai)銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)里面(mian)的(de)(de)(de)(de)(de)表面(mian)上(shang)(shang)劃一(yi)下，把劃出(chu)來的(de)(de)(de)(de)(de)材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)(zhi)和(he)剛才在(zai)(zai)(zai)外(wai)面(mian)劃出(chu)來的(de)(de)(de)(de)(de)材(cai)(cai)料進行相(xiang)互比(bi)(bi)(bi)較(jiao)，要(yao)(yao)是相(xiang)同的(de)(de)(de)(de)(de)，那就是說整個材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)(zhi)都還比(bi)(bi)(bi)較(jiao)好(hao)的(de)(de)(de)(de)(de)。要(yao)(yao)是顏(yan)色是不同的(de)(de)(de)(de)(de)或(huo)者(zhe)是有(you)別(bie)(bie)的(de)(de)(de)(de)(de)東西，那就是這(zhe)種銅(tong)(tong)(tong)(tong)管(guan)(guan)(guan)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)(zhi)是比(bi)(bi)(bi)較(jiao)差的(de)(de)(de)(de)(de)了(le)，可(ke)(ke)能(neng)里面(mian)加了(le)別(bie)(bie)的(de)(de)(de)(de)(de)像鐵這(zhe)些(xie)東西。
