延长冷拔无缝钢管使用寿命的方法

大家都知道冷拔无缝钢管要是放着露天久了,或者有什么摩擦,不锈钢表面的氧化层就会损伤,然后在潮湿的空气环境下就会被氧化生锈。其原理就是冷拔无缝钢管的表明渡化膜中耐腐蚀性比较弱的部分会因为自激反应形成点腐蚀反应,生产小小的孔,会和接近的氯离子容成很强的腐蚀性的溶液,加快腐蚀的速度。再加上不锈钢内部的晶间腐蚀开裂,都会对不锈钢板的表面的渡化膜进行破坏。

Everyone knows that if the cold-drawn seamless steel pipe is kept open for a long time or there is any friction, the oxide layer on the surface of stainless steel will be damaged, and then it will be oxidized and rusted in the humid air environment. The principle is that the weak corrosion resistance in the transition film of cold-drawn seamless steel pipe will form point corrosion reaction due to self-excitation reaction, and produce small holes, which will be condensed into strong corrosive solution with close chloride ions, so as to accelerate the corrosion rate. Additionally, intergranular corrosion cracking in stainless steel will destroy the transition film on the surface of stainless steel.

但是冷拔无缝钢管就具备得天独厚的优势,因为它的表面不易被氧化,这主要和组成冷拔无缝钢管的原材料是分不开的。精密不锈钢管是靠其表面形成的一层极薄而坚固细密的稳定的富铬氧化膜(防护膜),防止氧原子的继续渗入、继续氧化,而获得抗锈蚀的能力。

However, cold-drawn seamless steel tube has unique advantages, because its surface is not easy to be oxidized, which is mainly related to the raw materials of cold-drawn seamless steel tube. Precision stainless steel tube is formed by a thin, firm and compact chromium-rich oxide film (protective film) on its surface, which prevents oxygen atoms from penetrating into and oxidizing continuously, and obtains the ability to resist corrosion.

因此,对冷拔无缝钢管的表层要进行一定层次的清洁保养,来更好的延长冷拔无缝钢管的使用寿命。冷拔无缝钢管要尽量放在密封的地方。

Therefore, the surface of cold-drawn seamless steel tubes should be cleaned and maintained at a certain level to prolong the service life of cold-drawn seamless steel tubes. Cold-drawn seamless steel pipe should be kept in a sealed place as far as possible.
