　　不銹鋼通風管道的壁厚標準通常根據管徑、使用環境、工作壓力、流體性質和運行環境溫度等因素確定。以下是一些常見的不銹鋼風管壁厚標準：

　　The wall thickness standard for stainless steel ventilation ducts is usually determined based on factors such as pipe diameter, usage environment, working pressure, fluid properties, and operating environment temperature. Here are some common wall thickness standards for stainless steel ducts:

　　管徑在50mm以下 ：壁厚通常在 0.8-1.0mm 。

　　The diameter of the pipe is below 50mm: the wall thickness is usually between 0.8-1.0mm.

　　管徑在50-100mm ：壁厚通常在 1.0-1.2mm 。

　　The diameter of the pipe is between 50-100mm, and the wall thickness is usually between 1.0-1.2mm.

　　管徑在100-200mm ：壁厚通常在 1.2-1.5mm 。

　　The diameter of the pipe is 100-200mm, and the wall thickness is usually 1.2-1.5mm.

　　管徑在200mm以上 ：壁厚通常在 1.5mm以上 。

　　Pipe diameter above 200mm: wall thickness is usually above 1.5mm.

　　室外或有腐蝕性氣體環境 ：壁厚需要加厚。

　　Outdoor or corrosive gas environment: Wall thickness needs to be increased.

　　高壓力環境 ：壁厚需要相應增大。

　　High pressure environment: The wall thickness needs to be increased accordingly.

　　對于焊接風管，還有以下要求：

　　For welding air ducts, there are also the following requirements:

　　壁厚≥ 0.5mm 。

　　Wall thickness ≥ 0.5mm.

　　板材焊接應采用 TIG 或 MIG 焊接技術。

　　TIG or MIG welding technology should be used for plate welding.

　　直徑≤ 150mm 的風管應采用 D級品質 ，其余應采用 C級品質 。

　　Ducts with a diameter of ≤ 150mm should be of D-grade quality, while others should be of C-grade quality.

　　不銹鋼矩形風管邊長 10-50cm 的正壓厚度為 0.5mm ，高壓厚度為 0.75mm 。

　　The positive pressure thickness of the stainless steel rectangular air duct with a side length of 10-50cm is 0.5mm, and the high pressure thickness is 0.75mm.

　　不銹鋼螺旋風管厚度標準通常為 2.5mm-16mm 。

　　The thickness standard for stainless steel spiral ducts is usually 2.5mm-16mm.

　　不銹鋼異形風管壁厚標準根據具體規格和用途有不同的要求。

　　The wall thickness standard for stainless steel irregular ducts varies depending on specific specifications and applications.

　　請注意，這些標準可能因國家和地區而異，具體選擇時應參考當地行業標準，如GB/T 13793、GB/T 19216等。

　　Please note that these standards may vary by country and region, and specific selection should refer to local industry standards such as GB/T 13793, GB/T 19216, etc.
