冷拔無（wú）縫鋼管的（de）腐蝕性的（de）問（wèn）題已經是一個比較嚴重的問題了，很多的廠家也（yě）是因為（wéi）腐蝕成本也是（shì）在不斷地進行升高，每年光腐蝕導致的直接的經濟損失（shī）就達到（dào）了數億元（yuán），是一筆非常龐大（dà）的開支。所以說應該對於腐蝕性應該及時進行處理，挽回（huí）經濟（jì）損失。冷拔無縫鋼管為（wéi）什麽會腐蝕呢?這些因素或（huò）者是與腐蝕有著直（zhí）接的（de）關係。具體的話我們直（zhí）接進行看一下相關（guān）的（de）介紹：
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（xiān）是外界條件的影響。主要是先看管道周圍的介質特性、溫度，以及（jí）管道周圍所處的介質（zhì）是不是具有腐蝕性。因為介質腐（fǔ）蝕性的高低與土壤所含（hán）的各（gè）項微生物有著密切（qiē）的關（guān）係。並且如果是長輸（shū）管道的話，土壤環境性質更加複雜。除此之外，管道所處環境的溫度也會影響冷拔無縫（féng）鋼管的腐（fǔ）蝕，如果溫度較高，腐蝕的（de）速度也會加快（kuài），而溫度低（dī）則腐蝕速度減慢。
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。管道在架設的時候要（yào）做好防腐工作或者直接（jiē）使用防腐冷拔（bá）無縫鋼管，管道遭到腐（fǔ）蝕的原因是因為管道的防腐層遭到了破壞。防腐層和管道表麵一旦脫離，就會自然造成防腐（fǔ）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.
以上就是冷拔無縫（féng）鋼管腐蝕性（xìng）的主要的原因，大家可以避免這些原因，找到解決防止腐蝕性的辦法，這樣的話才能夠獲得比較好的效果!
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!
