、　　不銹鋼(gang)焊接風管是一種(zhong)在通風、空調、排(pai)煙(yan)系統中廣泛使用的管道，因其材質(zhi)優良(liang)、強度高、耐(nai)腐蝕、耐(nai)高溫等特點，被(bei)視為一種(zhong)高品質(zhi)的風管。

　　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(wu)壽命相持平）；

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

　　耐腐(fu)蝕性(xing)（因鈍化作用在(zai)表面形(xing)成一(yi)層(ceng)堅韌致密的富鉻氧化物保護(hu)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(yu)保(bao)溫（不銹鋼管(guan)的(de)熱導(dao)率是銅管(guan)的(de)1/25，是普通鋼管(guan)的(de)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(qiang)度（304不銹鋼管(guan)的(de)抗拉強(qiang)度是鋼管(guan)的(de)2倍，塑料(liao)管(guan)的(de)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(xiu)鋼(gang)焊接(jie)風(feng)管(guan)的厚度(du)(du)是直接(jie)影(ying)響其使(shi)用(yong)壽命、承載能力和性的因素之一(yi)，必須符合標(biao)準(zhun)(zhun)和行(xing)(xing)業標(biao)準(zhun)(zhun)。標(biao)準(zhun)(zhun)有(you)《通風(feng)與(yu)空(kong)調系統設計規(gui)范(fan)》、《建(jian)筑機電設備安(an)裝工程驗(yan)收規(gui)范(fan)》等(deng)；行(xing)(xing)業標(biao)準(zhun)(zhun)有(you)《鋼(gang)質空(kong)氣管(guan)道(dao)》、《不銹(xiu)鋼(gang)風(feng)管(guan)》等(deng)。這些標(biao)準(zhun)(zhun)都對焊接(jie)風(feng)管(guan)的厚度(du)(du)有(you)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;

　　標準(zhun)要求：壁厚(hou)≥0.5mm；板材焊接采用TIG或(huo)MIG焊接技術；直(zhi)徑≤150mm應采用D級品(pin)質(zhi)，其余應采用C級品(pin)質(zhi)。同城市燃氣(qi)管道相交的(de)部(bu)位，壁厚(hou)應不小(xiao)于(yu)1.0mm；部(bu)分輕質(zhi)建筑(zhu)(zhu)，壁厚(hou)應不小(xiao)于(yu)0.8mm。風管壁厚(hou)應符(fu)合當地建筑(zhu)(zhu)設計標準(zhun)的(de)規定；墻壁上安裝(zhuang)的(de)風管應采用厚(hou)度≥1.0mm的(de)不銹鋼風管。

　　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(an)裝(zhuang)時要將(jiang)不銹(xiu)鋼風管(guan)的焊縫朝(chao)上(shang)，如果(guo)風管(guan)有(you)輕微凹(ao)陷不影響使用時，可(ke)將(jiang)凹(ao)陷面朝(chao)上(shang)。

　　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.
