儀表管件的五大防腐措施

  1. 儀表管件足球比分選用耐腐蝕材料。在實際生產中, 介質的腐蝕非常復雜, 即使在使用介質的儀表管件材料中, 介質的濃度、溫度、壓力、介質的腐蝕程度也不同。介電溫度增加 10度, 腐蝕率約為1-3倍。介質濃度對儀表管件材料的腐蝕, 如鉛在小硫酸中的濃度, 腐蝕非常小, 當濃度超過96% 時, 腐蝕急劇增加。相比之下, 當硫酸濃度在50% 左右時, 碳鋼的腐蝕是最嚴重的, 當濃度增加到6% 時, 腐蝕會急劇減少。由于鋁的濃度超過80% 的濃硝酸腐蝕非常強烈, 但在低濃度的硝酸腐蝕是嚴重的。不銹鋼雖然對稀硝酸的耐腐蝕性很強, 但在95% 以上的濃硝酸腐蝕加劇。從以上例子中我們可以看出, 正確選擇儀表管件材料應根據具體情況, 分析各種影響腐蝕的因素, 根據相關的防腐蝕手冊選擇材料。
