style="text-indent:25px">在不銹鋼無縫管表面上，游離鐵都會生銹并使不銹鋼產(chǎn)生腐蝕。因此，必須去除。浮粉一般可隨粉塵一起去除掉。有些粘著力很強，必須按嵌入的鐵處理。除粉塵外，表面鐵的來源很多，其中包括用普通碳鋼鋼絲刷清理和用以前在普碳鋼，低合金鋼或鑄鐵件上使用過的砂子、玻璃珠或其它磨料進行噴丸處理，或在不銹鋼部件及設(shè)備附近對前面提到的非不銹鋼制品進行修磨。在下料或吊過過程中如果不對不銹鋼采取保護措施，鋼絲繩、吊具和工作臺面上的鐵很容易嵌入或玷污表面。厚壁不銹鋼無縫管304供應(yīng)商若欲獲得尺寸更小和質(zhì)量更好的不銹鋼無縫管，必須采用冷軋、冷拔或者兩者聯(lián)合的方法。</p><div
