廠傢介紹預防冷拔無縫鋼管遭受腐蝕的方法

冷拔無縫鋼管生銹也是常見的問題，但生銹就會影響使用壽命，目前無法從根本上解決腐蝕問題，可以做出一些預防措施，將腐蝕程度降到最低。工具除銹是其中的一個方法，但並不是長久之計，也隻能是冷拔無縫鋼管出現銹蝕之後采取的抑制擴散措施。冷拔無縫鋼管廠傢采用的工具除銹不能及時的解決問題，有時候工具除銹效果也不是很理想，並且還會破壞冷拔無縫鋼管的表層，此時我們可以嘗試使用酸洗的方法，雖然也會有負面影響，相對來說效果是比較理想的。酸洗去除銹蝕一般有化學和電解兩種方法，管道防腐隻采用化學酸洗，可以去除氧化皮、鐵銹、舊塗層，有時可用其作為噴砂除銹後的再處理。化學清洗雖然能使表面達到一定的清潔度和粗糙度，但其錨紋淺，而且易對环境造成污染。根據實際情況選用以上的除銹方案，避免冷拔無縫鋼管腐蝕程度進一步加深。
Cold-drawn seamless steel pipe rusting is also a common problem, but rusting will affect the service life. At present, the corrosion problem can not be fundamentally solved. Some preventive measures can be taken to minimize the degree of corrosion. Tool rust removal is one of the methods, but it is not a long-term solution, but also can only be taken to inhibit the diffusion of印花地坪 cold-drawn seamless steel pipe after rust. The tool used by the cold-drawn seamless steel pipe manufacturer can not solve the problem in time. Sometimes the effect of tool rust removal is not very ideal, and it will also destroy the surface of the cold-drawn seamless steel pipe. At this time, we can try to use acid pickling method, although there will be negative effects, the effect is relatively ideal. Pipeline corrosion is usually removed by chemical and electrolytic methods. Pipeline corrosion protection only uses chemical pickling, which can remove oxide scales, rust and old coatings. Sometimes it can be used as a reprocessing after sandblasting and rust removal. Although chemical cleaning can achieve a certain degree of cleanliness and roughness of the surface, its anchor lines are shallow and easy to pollute the environment. According to the actual situation, the above rust removal schemes are selected to avoid further corrosion of cold-环氧地坪drawn seamless steel tubes.
