国内外螺旋焊管厂采用的在线移动式切管设备有以下几种:熔剂下电弧飞切机、火焰气割机、等离子飞切机、飞锯机、飞铣切管机等。根据国内的使用经验证明:飞铣机具有切管成本低、切割质量好,钢材损耗少等优点。因而受到了某些钢管厂的重视和欢迎。 Spiral welded pipe plant at home and abroad using the online mobile pipe cutting equipment are the following: flux arc fly cutting machine, flame gas cutting machine, plasma cutting machine, flying saw machine, milling cutter and so on. According to the domestic experience shows that: flying milling machine has the advantages of low cost of cutting pipe, good cutting quality and less steel loss. Therefore, it has been valued and welcomed by some steel pipe mills.
