危包鋼桶的基本條件

為了符合鋼桶(tong)應有的(de)職能，危(wei)(wei)包鋼桶(tong)，應根據危(wei)(wei)險貨物的(de)性質和運輸特點，具備以下條(tiao)件：

1．生(sheng)產鋼桶(tong)所用(yong)的鋼板的厚度、冷軋鋼板或鍍鋅、鍍錫鋼板以及輔助(zhu)材料等，都(dou)要與(yu)，所裝危(wei)險貨物的性(xing)質相(xiang)適應。

2．鋼(gang)桶應具有(you)一(yi)(yi)定的(de)強(qiang)度，開口鋼(gang)桶廠家，能(neng)夠(gou)承受正常(chang)運輸條件(jian)下(xia)的(de)一(yi)(yi)般壓力小．同一(yi)(yi)種危(wei)險貨物單件(jian)重量越(yue)大，危(wei)險性就越(yue)大，因而(er)對包裝鋼(gang)桶的(de)強(qiang)度要求(qiu)也(ye)越(yue)高。對盛裝低沸點液體(ti)的(de)鋼(gang)桶強(qiang)度，必須具有(you)足夠(gou)的(de)安(an)全系數，以承受包裝內部可能(neng)產生較(jiao)高的(de)壓力。總之，對可能(neng)造成危(wei)害較(jiao)大的(de)貨物，其(qi)鋼(gang)桶強(qiang)度要求(qiu)應更高。

3．鋼桶的(de)封口要(yao)求嚴密(mi)。并符(fu)合(he)所裝(zhuang)危，險貨(huo)物(wu)的(de)性質，特別是易揮發(fa)腐蝕，陡強的(de)物(wu)品(pin)。但是，全開口鋼桶，有(you)的(de)危險品(pin)則反，要(yao)求設(she)有(you)通(tong)風氣孔或排氣閥，這要(yao)根據所裝(zhuang)危險貨(huo)物(wu)的(de)特殊性質來確定。

鋼(gang)桶(tong)(tong)(tong)(tong)內(nei)涂(tu)的(de)確定(ding)用(yong)(yong)戶(hu)可以由(you)鐵桶(tong)(tong)(tong)(tong)供(gong)應(ying)商(shang)(shang)提(ti)(ti)供(gong)各種內(nei)涂(tu)的(de)樣板，在所(suo)要求(qiu)的(de)z高溫度(du)、長時間、以及(ji)其它(ta)各種可能情(qing)況下進行用(yong)(yong)戶(hu)產(chan)(chan)品(pin)浸泡試驗(yan)，分析(xi)涂(tu)層是(shi)否變(bian)(bian)化后，用(yong)(yong)戶(hu)確定(ding)適合(he)的(de)內(nei)涂(tu)層。 閉口(kou)桶(tong)(tong)(tong)(tong)螺圈內(nei)襯圈應(ying)根據(ju)用(yong)(yong)戶(hu)盛裝產(chan)(chan)品(pin)而確定(ding)，開口(kou)鋼(gang)桶(tong)(tong)(tong)(tong)價格，采用(yong)(yong)不同材料。用(yong)(yong)戶(hu)可以由(you)鋼(gang)桶(tong)(tong)(tong)(tong)供(gong)應(ying)商(shang)(shang)提(ti)(ti)供(gong)不同材料襯圈進行浸泡，分析(xi)其溶漲變(bian)(bian)形情(qing)況后確定(ding)。 第一(yi)次用(yong)(yong)桶(tong)(tong)(tong)(tong)用(yong)(yong)戶(hu)選用(yong)(yong)鐵桶(tong)(tong)(tong)(tong)程(cheng)序 1） 用(yong)(yong)戶(hu)和鐵桶(tong)(tong)(tong)(tong)鋼(gang)桶(tong)(tong)(tong)(tong)供(gong)應(ying)商(shang)(shang)初步洽談，或(huo)前期準備式作； 2）送小(xiao)樣用(yong)(yong)戶(hu)多次確認，用(yong)(yong)戶(hu)提(ti)(ti)意見(jian)和建議； 3）小(xiao)批量(liang)試用(yong)(yong)，用(yong)(yong)戶(hu)再(zai)次確認，并提(ti)(ti)意見(jian)和建議； 4）中批量(liang)試用(yong)(yong)至成批供(gong)桶(tong)(tong)(tong)(tong)。 5．開口(kou)桶(tong)(tong)(tong)(tong)密封性能商(shang)(shang)檢證書(shu) 如客(ke)戶(hu)需用(yong)(yong)53、55加侖開口(kou)桶(tong)(tong)(tong)(tong)盛裝油(you)漆、膠(jiao)狀物或(huo)液(ye)體(ti)類產(chan)(chan)品(pin)出(chu)口(kou)，需向制桶(tong)(tong)(tong)(tong)廠(chang)索取開口(kou)桶(tong)(tong)(tong)(tong)液(ye)密性能商(shang)(shang)檢證
