不銹鋼焊接風(fēng)管是一種在通風(fēng)、空調(diào)、排煙系統(tǒng)中廣泛使用的管道，因其材質(zhì)優(yōu)良、強度高、耐腐蝕、耐高溫等特點，被視為一種高品質(zhì)的風(fēng)管。

　　具有：

　　較長的使用壽命（基本可以和建筑物壽命相持平）；

　　耐腐蝕性（因鈍化作用在表面形成一層堅韌致密的富鉻氧化物保護膜Dr2O3）；

　　耐熱與保溫（不銹鋼管的熱導(dǎo)率是銅管的1/25，是普通鋼管的1/4）；

　　及較高強度（304不銹鋼管的抗拉強度是鋼管的2倍，塑料管的8-10倍）。

　　不銹鋼焊接風(fēng)管的厚度是直接影響其使用壽命、承載能力和性的因素之一，必須符合標(biāo)準(zhǔn)和行業(yè)標(biāo)準(zhǔn)。標(biāo)準(zhǔn)有《通風(fēng)與空調(diào)系統(tǒng)設(shè)計規(guī)范》、《建筑機電設(shè)備安裝工程驗收規(guī)范》等；行業(yè)標(biāo)準(zhǔn)有《鋼質(zhì)空氣管道》、《不銹鋼風(fēng)管》等。這些標(biāo)準(zhǔn)都對焊接風(fēng)管的厚度有明確要求；

　　標(biāo)準(zhǔn)要求：壁厚≥0.5mm；板材焊接采用TIG或MIG焊接技術(shù)；直徑≤150mm應(yīng)采用D級品質(zhì)，其余應(yīng)采用C級品質(zhì)。同城市燃氣管道相交的部位，壁厚應(yīng)不小于1.0mm；部分輕質(zhì)建筑，壁厚應(yīng)不小于0.8mm。風(fēng)管壁厚應(yīng)符合當(dāng)?shù)亟ㄖO(shè)計標(biāo)準(zhǔn)的規(guī)定；墻壁上安裝的風(fēng)管應(yīng)采用厚度≥1.0mm的不銹鋼風(fēng)管。

　　在安裝時要將不銹鋼風(fēng)管的焊縫朝上，如果風(fēng)管有輕微凹陷不影響使用時，可將凹陷面朝上。

　　Stainless steel welded air duct is a widely used pipeline in ventilation, air conditioning, and smoke exhaust systems. Due to its excellent material, high strength, corrosion resistance, and high temperature resistance, it is considered a high-quality air duct.

　　具有：

　　have:

　　較長的使用壽命（基本可以和建筑物壽命相持平）；

　　Long service life (basically equivalent to the lifespan of a building);

　　耐腐蝕性（因鈍化作用在表面形成一層堅韌致密的富鉻氧化物保護膜Dr2O3）；

　　Corrosion resistance (due to passivation, a tough and dense chromium rich oxide protective film Dr2O3 is formed on the surface);

　　耐熱與保溫（不銹鋼管的熱導(dǎo)率是銅管的1/25，是普通鋼管的1/4）；

　　Heat resistance and insulation (the thermal conductivity of stainless steel pipes is 1/25 of copper pipes and 1/4 of ordinary steel pipes);

　　及較高強度（304不銹鋼管的抗拉強度是鋼管的2倍，塑料管的8-10倍）。

　　And higher strength (the tensile strength of 304 stainless steel pipes is twice that of steel pipes, and 8-10 times that of plastic pipes).

　　不銹鋼焊接風(fēng)管的厚度是直接影響其使用壽命、承載能力和性的因素之一，必須符合標(biāo)準(zhǔn)和行業(yè)標(biāo)準(zhǔn)。標(biāo)準(zhǔn)有《通風(fēng)與空調(diào)系統(tǒng)設(shè)計規(guī)范》、《建筑機電設(shè)備安裝工程驗收規(guī)范》等；行業(yè)標(biāo)準(zhǔn)有《鋼質(zhì)空氣管道》、《不銹鋼風(fēng)管》等。這些標(biāo)準(zhǔn)都對焊接風(fēng)管的厚度有明確要求；

　　The thickness of stainless steel welded air ducts is one of the factors that directly affects their service life, load-bearing capacity, and safety, and must comply with national and industry standards. National standards include "Design Specification for Ventilation and Air Conditioning Systems" and "Acceptance Specification for Installation Engineering of Building Mechanical and Electrical Equipment"; Industry standards include "Steel Air Pipelines", "Stainless Steel Ducts", etc. These standards have clear requirements for the thickness of welded air ducts;

　　標(biāo)準(zhǔn)要求：壁厚≥0.5mm；板材焊接采用TIG或MIG焊接技術(shù)；直徑≤150mm應(yīng)采用D級品質(zhì)，其余應(yīng)采用C級品質(zhì)。同城市燃氣管道相交的部位，壁厚應(yīng)不小于1.0mm；部分輕質(zhì)建筑，壁厚應(yīng)不小于0.8mm。風(fēng)管壁厚應(yīng)符合當(dāng)?shù)亟ㄖO(shè)計標(biāo)準(zhǔn)的規(guī)定；墻壁上安裝的風(fēng)管應(yīng)采用厚度≥1.0mm的不銹鋼風(fēng)管。

　　Standard requirement: Wall thickness ≥ 0.5mm; TIG or MIG welding technology is used for plate welding; Diameter ≤ 150mm should be of D-grade quality, while the rest should be of C-grade quality. The wall thickness at the intersection of gas pipelines in the same city should not be less than 1.0mm; For some lightweight buildings, the wall thickness should not be less than 0.8mm. The wall thickness of the air duct should comply with the local energy-saving design standards for buildings; The air ducts installed on the wall should be made of stainless steel with a thickness of ≥ 1.0mm.

　　在安裝時要將不銹鋼風(fēng)管的焊縫朝上，如果風(fēng)管有輕微凹陷不影響使用時，可將凹陷面朝上。

　　When installing, the weld seam of the stainless steel air duct should be facing upwards. If there is a slight depression in the air duct that does not affect use, the depression can be facing upwards.
