常耐用？當它表層出現這些現象時請注意了。

Constant use? Please pay attention when these phenomena appear on its surface.

現象一：不銹鋼螺旋風管的部分出現生銹。

Phenomenon 1: part of the stainless steel spiral air duct is rusted.

現象一：不銹鋼螺旋風管表層出現一些擦毛、臟物等。

Phenomenon 1: there are some scratches and dirt on the surface of stainless steel spiral air duct.

現象三：在焊接表層，其色調是呈灰黑色的，或是是有黃點或斑點。

2、不銹鋼螺旋風管在生產加工生產制造全過程中，就出現了浸蝕狀況，但并沒有立即開展解決。

2. The stainless steel spiral air duct was corroded in the whole process of manufacturing, but it was not solved immediately.

3、不銹鋼螺旋風管的焊接工藝沒有挑選恰當，也就是焊接工藝不善。

3. The welding process of stainless steel spiral air duct is not properly selected, that is, the welding process is poor.

4、不銹鋼螺旋風管電焊焊接好之后，沒有立即開展清理和。

4. The stainless steel spiral air duct was not cleaned and removed immediately after electric welding.
