冷拔无缝（féng）钢管的腐蚀性的问题已经是一个比较严重的（de）问题了，很多的厂家也是（shì）因为腐（fǔ）蚀成本也是在不断地进行升高（gāo），每年光腐蚀导致的直（zhí）接的经济损失就达到了数亿元，是一笔（bǐ）非常庞大的开支。所以说（shuō）应该对（duì）于（yú）腐蚀（shí）性应该（gāi）及时进行处（chù）理，挽回经（jīng）济损失。冷拔无缝钢管为什（shí）么会腐（fǔ）蚀呢?这些（xiē）因素或（huò）者（zhě）是与腐蚀有着直接的关系。具体的话我们直接进行看一下相关的（de）介（jiè）绍：
Corrosivity of cold-drawn seamless steel tubes has become a serious problem. Many manufacturers are also increasing the cost of corrosion. The direct economic loss caused by light corrosion every year reaches hundreds of millions of yuan, which is a huge expenditure. Therefore, corrosiveness should be dealt with in time to recover economic losses. Why are cold-drawn seamless steel tubes corroded? These factors are directly related to corrosion. Specifically, let's take a look at the relevant introduction directly. 1、首先是外界条件的影响。主要是（shì）先（xiān）看管道周围（wéi）的介（jiè）质特性、温度（dù），以及管道周围所处的介质是不是具有（yǒu）腐蚀性。因为介质腐蚀性的高低（dī）与土壤所含的各项微生（shēng）物有着密切的关系（xì）。并且如果是长输管道的话，土壤环境性质（zhì）更加复杂。除此（cǐ）之外，管（guǎn）道所处环境的（de）温度也会影响冷拔无缝钢管的（de）腐蚀，如果温度（dù）较高，腐蚀的速度也会加（jiā）快，而温度低则腐（fǔ）蚀（shí）速度减慢。
1. The first is the influence of external conditions. Mainly depends on the characteristics of the medium around the pipeline, temperature, and whether the medium around the pipeline is corrosive. Because the corrosiveness of the medium is closely related to the microorganisms in the soil. And if it is a long-distance pipeline, the soil environment is more complex. In addition, the temperature of pipeline environment will also affect the corrosion of cold-drawn seamless steel pipe. If the temperature is higher, the corrosion speed will be accelerated, while the corrosion speed will be slowed down when the temperature is low.

2、就是防腐失效。管道在（zài）架设的时（shí）候要做好防腐工（gōng）作或者（zhě）直接使用防腐冷（lěng）拔无缝钢管，管道遭到腐蚀（shí）的原因是因为管道的防腐层遭到（dào）了（le）破坏。防（fáng）腐层和管道表面一旦脱离（lí），就会自然造成防腐失效。
2. Corrosion protection is invalid. When pipeline is erected, it is necessary to do a good job of anti-corrosion or use anti-corrosion cold-drawn seamless steel pipe directly. The reason why pipeline is corroded is that the anti-corrosion layer of pipeline is damaged. Once the anticorrosive coating and pipeline surface are separated, it will naturally cause anticorrosive failure.
以上就是冷拔无缝钢管腐蚀（shí）性的主要的原因，大家可（kě）以避免这些原因，找（zhǎo）到解决防止（zhǐ）腐蚀性（xìng）的（de）办法，这样的话才（cái）能够获（huò）得比较好的（de）效果!
Above is the main reason for the corrosiveness of cold-drawn seamless steel tubes. We can avoid these reasons and find solutions to prevent corrosiveness, so that we can get better results!
