閉口(kou)鋼(gang)桶是指注入(ru)口(kou)和(he)透氣口(kou)孔徑不大于(yu)(yu)7cm的鋼(gang)桶（也稱非移動頂(ding)鋼(gang)桶） ， 廣泛(fan)用(yong)于(yu)(yu)盛裝液體狀態的化工、石油、食品(pin)等產品(pin)的出(chu)口(kou)包(bao)裝。在(zai)液體危(wei)險貨物的出(chu)口(kou)中，更離不開閉口(kou)鋼(gang)桶。按照ZBA870012-88《海運出(chu)口(kou)危(wei)險貨物包(bao)裝檢驗(yan)(yan)規程-性能檢驗(yan)(yan)》及GB325-91《包(bao)裝容器-鋼(gang)桶》的要求， 鋼(gang)桶的出(chu)廠(chang)檢驗(yan)(yan)和(he)型式檢驗(yan)(yan)均需進(jin)行1氣密試(shi)驗(yan)(yan)。

鋼(gang)桶(tong)的修(xiu)(xiu)補(bu)方(fang)法(fa) （1）傳統修(xiu)(xiu)補(bu)法(fa)——氣焊補(bu)漏 特點(dian)：熱(re)影(ying)響區(qu)比較(jiao)(jiao)(jiao)(jiao)大，能造成(cheng)表面(mian)氧(yang)(yang)化，桶(tong)身(shen)(shen)變形、卷邊內密封膠(jiao)(jiao)燒焦失效(xiao)，一點(dian)滲漏須(xu)補(bu)焊整(zheng)圈。 （2）釬焊修(xiu)(xiu)補(bu)法(fa) 特點(dian)：熱(re)影(ying)響區(qu)比較(jiao)(jiao)(jiao)(jiao)小(xiao)，不會致使桶(tong)身(shen)(shen)成(cheng)形。但(dan)補(bu)焊前處理比較(jiao)(jiao)(jiao)(jiao)復雜，工(gong)作(zuo)(zuo)效(xiao)率低。 （3）弧(hu)焊修(xiu)(xiu)補(bu)法(fa) 特點(dian)：熱(re)影(ying)響區(qu)比較(jiao)(jiao)(jiao)(jiao)小(xiao)，揚州閉(bi)(bi)口(kou)鋼(gang)桶(tong)，不會產(chan)生表面(mian)氧(yang)(yang)化，閉(bi)(bi)口(kou)包裝(zhuang)鋼(gang)桶(tong)，補(bu)焊效(xiao)果好，工(gong)作(zuo)(zuo)效(xiao)率相對較(jiao)(jiao)(jiao)(jiao)高(gao)。 （4）膠(jiao)(jiao)粘劑膠(jiao)(jiao)接(jie)法(fa) 特點(dian)：成(cheng)本(ben)低，工(gong)作(zuo)(zuo)，208l閉(bi)(bi)口(kou)鋼(gang)桶(tong)，操作(zuo)(zuo)簡單(dan)，但(dan)適用范圍(wei)有限。 2、鋼(gang)桶(tong)的應急修(xiu)(xiu)補(bu)方(fang)法(fa) （1）環氧(yang)(yang)樹脂補(bu)漏法(fa) 先配好補(bu)漏膠(jiao)(jiao)，再添入(ru)桶(tong)身(shen)(shen)接(jie)縫中，晾(liang)干即可，但(dan)適用范圍(wei)要注(zhu)意。 （2）輥(gun)輪再次(ci)壓(ya)緊法(fa) 必須(xu)返廠，采(cai)用較(jiao)(jiao)(jiao)(jiao)小(xiao)尺寸槽形的輥(gun)輪，再在封口(kou)機上滾壓(ya)一次(ci)，可減少80%以(yi)上的漏桶(tong)。
