今天山東無縫鋼管廠來和大家說（shuō）說精密無縫鋼管哪些位置容易（yì）欠酸洗。

  精（jīng）密無縫鋼管欠酸洗，就是酸液濃度不足/溫度不（bú）高/走（zǒu）帶速度太（tài）快的情況下，精密無縫（féng）鋼管有局部氧化鐵皮去除不幹淨、不充分。

  這（zhè）跟酸液的工藝（yì）有關係，跟精密無縫（féng）鋼管的表麵的情況也有關係。比如氧化鐵皮厚度不均勻，還（hái）有精密（mì）無縫鋼管表麵有浪形的情況下（xià），有的浸不到酸液（yè）裏麵等等都容易出現（xiàn）欠酸洗。

  所以，一般情況下，精密無縫鋼管欠酸洗的時候洗不幹（gàn）淨的位（wèi）置在哪？

  沒錯，就是在精密無縫鋼管頭尾和邊部（bù）了。從精密無（wú）縫鋼管長度方向上（shàng）來看頭尾的氧化（huà）鐵皮比較厚，容易欠（qiàn）酸洗。寬度方向上，就是邊部了。

  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.
