3)酸洗工工作前首先了解酸的濃度、溫度及本槽酸洗管的噸位。 </p> <p> 4)吊管時(shí)兩根吊帶要離開(kāi)端頭1.3米左右，防止吊彎鋼管，造成鍍鋅管內(nèi)漏;在往酸槽下管時(shí)，鋼管要傾斜15°，先下自己站立的一端，防止噴酸傷人。 </p> <p> 5)鋼管每次酸洗，重量在2～5噸為宜，時(shí)間5～15分鐘。 </p> <p> 6)鋼管在酸洗時(shí)要經(jīng)常振動(dòng)，在振動(dòng)過(guò)程中要把鋼管平放在酸槽的橫條石上，反復(fù)起動(dòng)一側(cè)吊帶3次后再起動(dòng)另一側(cè)吊帶3次，重復(fù)兩次后再吊起;振動(dòng)上升角度不大于15°。 </p><div style="width:100%;text-align: center;"><img

</p> <p> 2，存儲(chǔ)空間或倉(cāng)儲(chǔ)方，應(yīng)選擇在清潔干凈，無(wú)障礙的排水區(qū)域，遠(yuǎn)離有害氣體或粉塵的工廠和礦山。 </p> <p> 3，在清理雜草和所有碎片網(wǎng)站，清潔維護(hù)方。 </p> <p> 4，倉(cāng)庫(kù)不得有腐蝕性的材料堆放在一起與酸，堿，鹽，水泥等鋼的另一邊。 </p> <p> 5，不同品種的鋼材應(yīng)分別堆放，避免混淆，防止接觸腐蝕。 </p> <p> 6，應(yīng)根據(jù)地理?xiàng)l件選擇，一般封閉的倉(cāng)庫(kù)一般使用，即屋頂墻壁，門(mén)窗嚴(yán)密，設(shè)有通風(fēng)裝置庫(kù)。倉(cāng)儲(chǔ)要求晴天注意通風(fēng)，雨天注意去除水分，經(jīng)常保持適宜的儲(chǔ)存環(huán)境。 </p><div style="width:100%;text-align:
