厂家介绍预防冷拔无缝钢管遭受腐蚀的方法

2018-12-10 10:58:33 常州市星火铝艺制品有限公司 阅读

冷拔无缝钢管生锈也是常见的问题,但生锈就会影响使用寿命,目前无法从根本上解决腐蚀问题,可以做出一些预防措施,将腐蚀程度降到最低。工具除锈是其中的一个方法,但并不是长久之计,也只能是冷拔无缝钢管出现锈蚀之后采取的抑制扩散措施。冷拔无缝钢管厂家采用的工具除锈不能及时的解决问题,有时候工具除锈效果也不是很理想,并且还会破坏冷拔无缝钢管的表层,此时我们可以尝试使用酸洗的方法,虽然也会有负面影响,相对来说效果是比较理想的。酸洗去除锈蚀一般有化学和电解两种方法,管道防腐只采用化学酸洗,可以去除氧化皮、铁锈、旧涂层,有时可用其作为喷砂除锈后的再处理。化学清洗虽然能使表面达到一定的清洁度和粗糙度,但其锚纹浅,而且易对环境造成污染。根据实际情况选用以上的除锈方案,避免冷拔无缝钢管腐蚀程度进一步加深。

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 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-drawn seamless steel tubes.
