结构用无缝钢管的浮锈与生锈的辨别方式

发布日期:2019-06-30 浏览次数:3

结构用无缝钢管是通过钢厂管坯锯段,再在环形炉加热-穿孔-定径-校直-冷却-剧头-打包成为合格的成品,一般在送到使用方手里生产车间 是放不下这么多现货的,这就需要经销商放置一些现货,不过经销商一般没有大型的室内库,有的话也是成本太高,不合算。大多数都是室外仓库,结构用无缝钢管在室外放着就免不了风催日晒。

Seamless steel pipe for structure is packaged into qualified products by sawing section of billet in steel mill, then heated in annular furnace - perforation - sizing - straightening - cooling - dramatic head. Generally, so many spot goods can not be put in production workshop delivered to users, which requires dealers to place some spot goods, but dealers generally do not have large indoor storehouses, and some of them are too expensive and not cost-effective. Most of them are outdoor warehouses. Seamless steel tubes for structures can not avoid wind and sunshine when they are placed outdoors. 所谓浮锈顾名思义就是浮到结构用无缝钢管上面的一层锈,用毛巾或者其他的东西一抹就可以去掉的,简单的说浮锈也算是没锈,属于正常状态。结构用无缝钢管的生锈是年数久远,至少在1年以上在室外经过风催日晒的结构用无缝钢管,生锈的结构用无缝钢管上面有大大小小的麻坑,这也是结构用无缝钢管浮锈与生锈的唯一最大区别

The so-called floating rust, as its name implies, is a layer of rust floating on the seamless steel pipe for structural use. It can be removed with a towel or something else. Simply speaking, floating rust is also rust-free and belongs to the normal state. The rusting of seamless steel pipes for structures is a long time, at least for more than one year in the outdoor wind-induced sunshine structure with seamless steel pipes, rusted structure with seamless steel pipes above the size of pits, which is also the only biggest difference between floating rust and rust of seamless steel pipes for structures.
