3.保護(hù)材料的包裝和保護(hù)層鋼廠出廠前涂的防腐劑或其他鍍復(fù)及包裝，這是防止材料銹蝕的重要措施，在運(yùn)輸裝卸過程中須注意保護(hù)，不能損壞，可延長材料的保管期限 </p> <p> 4.保持倉庫清潔、加強(qiáng)材料養(yǎng)護(hù) </p> <p> (1)材料在入庫前要注意防止雨淋或混入雜質(zhì)，無縫方管對已經(jīng)淋雨或弄污的材料要按其性質(zhì)采用不同的方法擦凈，如硬度高的可用鋼絲刷，硬度低的用布、棉等物; </p> <p> (2)材料入庫后要經(jīng)常檢查，如有銹蝕，應(yīng)清理銹蝕層; </p> <p> (3)一般鋼管表面清理于凈后，不必涂油，但對質(zhì)量鋼、合金薄鋼板、薄壁管、合金鋼管等，除銹后其內(nèi)外表面均需涂防銹油后再存放; </p> <p> (4)對銹蝕較嚴(yán)重的鋼管，除銹后不宜長期保管，應(yīng)盡快使用。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
