专注通风管道加工·排烟罩

　　不锈钢焊接风管是一种在通风、空调、排烟系统中广泛使用的管道，因其材质优良、强度高、耐腐蚀、耐高温等特点，被视为一种高品质的风管。

　　具有：

　　较长的使用寿命（基本可以和建筑物寿命相持平）；

　　耐腐蚀性（因钝化作用在表面形成一层坚韧致密的富铬氧化物保护膜Dr2O3）；

　　耐热与保温（不锈钢管的热导率是铜管的1/25，是普通钢管的1/4）；

　　及较高强度（304不锈钢管的抗拉强度是钢管的2倍，塑料管的8-10倍）。

　　不锈钢焊接风管的厚度是直接影响其使用寿命、承载能力和性的因素之一，必须符合标准和行业标准。标准有《通风与空调系统设计规范》、《建筑机电设备安装工程验收规范》等；行业标准有《钢质空气管道》、《不锈钢风管》等。这些标准都对焊接风管的厚度有明确要求；

　　标准要求：壁厚≥0.5mm；板材焊接采用TIG或MIG焊接技术；直径≤150mm应采用D级品质，其余应采用C级品质。同城市燃气管道相交的部位，壁厚应不小于1.0mm；部分轻质建筑，壁厚应不小于0.8mm。风管壁厚应符合当地建筑设计标准的规定；墙壁上安装的风管应采用厚度≥1.0mm的不锈钢风管。

　　在安装时要将不锈钢风管的焊缝朝上，如果风管有轻微凹陷不影响使用时，可将凹陷面朝上。

　　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:

　　较长的使用寿命（基本可以和建筑物寿命相持平）；

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

　　耐腐蚀性（因钝化作用在表面形成一层坚韧致密的富铬氧化物保护膜Dr2O3）；

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

　　耐热与保温（不锈钢管的热导率是铜管的1/25，是普通钢管的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);

　　及较高强度（304不锈钢管的抗拉强度是钢管的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).

　　不锈钢焊接风管的厚度是直接影响其使用寿命、承载能力和性的因素之一，必须符合标准和行业标准。标准有《通风与空调系统设计规范》、《建筑机电设备安装工程验收规范》等；行业标准有《钢质空气管道》、《不锈钢风管》等。这些标准都对焊接风管的厚度有明确要求；

　　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;

　　标准要求：壁厚≥0.5mm；板材焊接采用TIG或MIG焊接技术；直径≤150mm应采用D级品质，其余应采用C级品质。同城市燃气管道相交的部位，壁厚应不小于1.0mm；部分轻质建筑，壁厚应不小于0.8mm。风管壁厚应符合当地建筑设计标准的规定；墙壁上安装的风管应采用厚度≥1.0mm的不锈钢风管。

　　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.

　　在安装时要将不锈钢风管的焊缝朝上，如果风管有轻微凹陷不影响使用时，可将凹陷面朝上。

　　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.
