　　不銹鋼通風(fēng)管道的壁厚標(biāo)準(zhǔn)通常根據(jù)管徑、使用環(huán)境、工作壓力、流體性質(zhì)和運(yùn)行環(huán)境溫度等因素確定。以下是一些常見(jiàn)的不銹鋼風(fēng)管壁厚標(biāo)準(zhǔn)：

　　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(huán)境 ：壁厚需要加厚。

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

　　高壓力環(huán)境 ：壁厚需要相應(yīng)增大。

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

　　對(duì)于焊接風(fēng)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(yīng)采用 TIG 或 MIG 焊接技術(shù)。

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

　　直徑≤ 150mm 的風(fēng)管應(yīng)采用 D級(jí)品質(zhì) ，其余應(yīng)采用 C級(jí)品質(zhì) 。

　　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(fēng)管邊長(zhǎng) 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(fēng)管厚度標(biāo)準(zhǔn)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(fēng)管壁厚標(biāo)準(zhǔn)根據(jù)具體規(guī)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(qǐng)注意，這些標(biāo)準(zhǔn)可能因國(guó)家和地區(qū)而異，具體選擇時(shí)應(yīng)參考當(dāng)?shù)匦袠I(yè)標(biāo)準(zhǔn)，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.
