碳化鉻NM500耐磨鋼管上是怎么開孔的

碳化鉻NM500耐磨鋼管上是怎么開孔的
      以前在現場的時候,開孔都是施工隊用氣割把碳化鉻NM500耐磨鋼管開孔,讓我很震撼,今天又查了不少施工規范,沒找到怎樣開孔的說法。有的只是開孔補強。請問都有哪些工具用來給碳化鉻NM500耐磨鋼管開孔,我覺得開孔應該是機械開孔才對。

      碳化鉻NM500耐磨鋼管原則上不允許直接開口,最好還是使用管件,非要開的話、
      1、碳鋼管可以用氣割,也有用焊條直接融掉開口的
      2、不銹鋼一般用等離子開口
      3、還有用切割片加磨光機開口的
      4、最好的辦法還是用開孔器開口,這樣最好

      最最最常見的就是氣割開孔。即便是用三通也是割去一段直管段再焊上這個三通,這割的還是氣焊,一個意思。
