| 螺旋风管是用金属带料卷制成螺旋形咬缝的薄壁管，圆形，无焊接，不漏气，不漏水，多用于送风和散装物料输送，代替传统的白铁管(即手工咬缝铁管)。是风管的一种，全机制，直管无需手工敲打。其主要用途如下: Spiral air duct is a thin-walled pipe with spiral seam made of metal strip coil. It is round, non-welded, non-leaking and non-leaking. It is mostly used for air supply and bulk material transportation instead of traditional white iron pipe (i.e. manual seam-biting iron pipe). It is a kind of air duct, full mechanism, straight pipe does not need to be knocked by hand. Its main uses are as follows: (1) 送风，包括通气，如送鲜风和排气，这个范围很广，如工厂车间，生产场地空气，由于有害气体产生需要排出室外，又需要把室外空气输送至室内。这时就要使用流量大而压力小的空气输送管道，螺旋风管就最适用，一般情况下使用镀锌铁管，有腐蚀性及特别潮湿场所使用不锈钢管。 (1) Air supply, including ventilation, such as fresh air supply and exhaust, covers a wide range of areas, such as factory workshops and production sites. Because of the generation of harmful gases, it is necessary to discharge outdoor air and convey outdoor air to indoors. At this time, it is necessary to use air conveying pipelines with large flow and low pressure. Spiral air ducts are most suitable. Generally, galvanized iron pipes are used, and stainless steel pipes are used in corrosive and especially humid places. (2) 送冷风。最常见的是中央空调的管道，这种管道需要加保温材料。螺旋风管可内贴保温材料，外表看来美观。 (2) cold air supply. The most common is the central air-conditioning pipeline, which requires insulation materials. The spiral air duct can be insulated with heat preservation material and has a beautiful appearance. (3) 排油烟。饭店、酒楼、宾馆的厨房扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训均有大量油烟产生，需要排出，使用圆形的风管就是油烟囱。在这里，螺旋风管该叫做油烟管。 (3) Fume exhaust. The kitchens of hotels, restaurants and hotels all have a lot of oil fumes, which need to be discharged. The use of circular air ducts is the oil chimney. Here, the spiral duct should be called lampblack. |
