  当我们选择通风管道时,要了解颜色标记的方法,了解选择时可以根据自己的情况做出选择,避免混搭现象,也不要被厂家的花言乱语所迷惑,自己去识别,看看有哪些方法?
  When we choose ventilation ducts, we should know the method of color marking, and we can make choices according to our own situation to avoid mixing phenomenon. We should not be confused by the chatter of the manufacturer. We should identify and see what methods are available.
  1. 标记管道全长;

  下面小编对每个人下面的烟道设置和耐火极限应满足以下要求:
  The following subsection shall meet the following requirements for each person's lower flue setting and fire resistance limit:
  1排烟管及其连接部件应能在280℃下连续30分钟保证其结构完整性。
  1. The exhaust pipe and its connecting parts should be able to ensure its structural integrity for 30 minutes continuously at 280 C.
