今天山东无缝钢管厂来和大家说说精密无缝钢管哪些位置容易欠酸洗。

  精密无缝钢管欠酸洗，就是酸液浓度不足/温度不高/走带速度太快的情况下，精密无缝钢管有局部氧化铁皮去除不干净、不充分。

  这跟酸液的工艺有关系，跟精密无缝钢管的表面的情况也有关系。比如氧化铁皮厚度不均匀，还有精密无缝钢管表面有浪形的情况下，有的浸不到酸液里面等等都容易出现欠酸洗。

  所以，一般情况下，精密无缝钢管欠酸洗的时候洗不干净的位置在哪？

  没错，就是在精密无缝钢管头尾和边部了。从精密无缝钢管长度方向上来看头尾的氧化铁皮比较厚，容易欠酸洗。宽度方向上，就是边部了。

  Today the shandong precision seamless steel pipe seamless steel pipe to and you talk about where to owe pickling.

  Precision seamless steel tube owe pickling, acid concentration is less than/temperature under the condition of high/walk too fast, precision seamless steel tube with partial oxidation of iron removal is not clean and inadequate.

  This has something to do with the acid process, with precision seamless steel tube surface is also have a relationship.Such as tin oxide thickness is not uniform, and precision seamless steel tube surface is under the condition of wave shape, some acid leaching is less than the inside, and so on are prone to owe pickling.

  So, usually, precision seamless steel tube owe pickling when the position of the wash not clean?

  Yes, in a precision seamless steel tube end and side.From the precision seamless steel tube length direction look at the tail of tin oxide is thick, easy to owe pickling.Width direction, is the edge.
