危包鋼桶的基本條件

為(wei)了符合鋼桶應有的職(zhi)能，閉口鋼桶廠(chang)家(jia)，危(wei)包鋼桶，應根據危(wei)險貨物的性質(zhi)和運輸特點，具備以下條件：

1．生產鋼桶所用的鋼板(ban)的厚度、冷軋(ya)鋼板(ban)或鍍(du)鋅、鍍(du)錫鋼板(ban)以(yi)及輔助材料等，都要與，所裝危險貨物的性質相適應。

2．鋼桶(tong)應具有(you)一定的強度，能夠承受(shou)正(zheng)常(chang)運輸條(tiao)件下(xia)的一般(ban)壓力小．同一種危險貨(huo)物單(dan)件重量越(yue)大，危險性就越(yue)大，因而對(dui)包(bao)裝(zhuang)鋼桶(tong)的強度要求(qiu)也越(yue)高。對(dui)盛裝(zhuang)低(di)沸點(dian)液體(ti)的鋼桶(tong)強度，必須具有(you)足夠的安全系(xi)數，以承受(shou)包(bao)裝(zhuang)內(nei)部(bu)可(ke)(ke)能產(chan)生較(jiao)高的壓力。總之(zhi)，對(dui)可(ke)(ke)能造成(cheng)危害較(jiao)大的貨(huo)物，其鋼桶(tong)強度要求(qiu)應更高。

3．鋼桶的(de)封(feng)口要求嚴密。并符合所(suo)裝危，險(xian)貨物的(de)性質，特(te)(te)別是(shi)易揮(hui)發腐蝕，陡強的(de)物品。但是(shi)，有的(de)危險(xian)品則反，要求設(she)有通風氣孔或排氣閥(fa)，這要根據所(suo)裝危險(xian)貨物的(de)特(te)(te)殊性質來確定。

鋼桶的優勢

1、經(jing)濟效(xiao)益顯著(zhu) 減小用材厚度，節約了原材料，給企業帶來的經(jing)濟效(xiao)益是顯著(zhu)的。

2、堆(dui)碼運輸(shu)方便(bian)，未(wei)(wei)縮(suo)(suo)頸(jing)的(de)(de)桶底比(bi)較(jiao)容易地套(tao)堆(dui)在縮(suo)(suo)頸(jing)后的(de)(de)桶頂上，相(xiang)對(dui)平穩安(an)全。反(fan)之，縮(suo)(suo)頸(jing)后的(de)(de)桶底也(ye)比(bi)較(jiao)容易地套(tao)堆(dui)在未(wei)(wei)縮(suo)(suo)頸(jing)的(de)(de)桶頂上，但未(wei)(wei)縮(suo)(suo)頸(jing)的(de)(de)桶頂的(de)(de)強(qiang)度并未(wei)(wei)增強(qiang)，僅(jin)僅(jin)方便(bian)堆(dui)碼。錐(zhui)形鋼桶的(de)(de)空(kong)桶可以桶套(tao)桶的(de)(de)運輸(shu)，閉(bi)口鋼桶批發，增加(jia)了運量，降(jiang)低了運輸(shu)成本，很受歡迎。但桶口不能縮(suo)(suo)頸(jing)，因而桶口的(de)(de)強(qiang)度未(wei)(wei)增強(qiang)，只能縮(suo)(suo)桶底，否則，就失去了錐(zhui)形桶的(de)(de)優勢(shi)。
