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 material roll. It is round, no welding, no air leakage and no water leakage. It is mostly used for air supply and bulk material transportation to replace the traditional white iron pipe (i.e. manual seam iron pipe). It is a kind of air duct with full mechanism. The straight pipe does not need to be knocked manually. Its main uses are as follows:（1）送风 (1) Air supply 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。 It includes ventilation, such as fresh air supply and exhaust. This range is very wide, such as the air in factory workshops and production sites. Due to the generation of harmful gases, it needs to be discharged outdoors, and the outdoor air needs to be transported indoors. At this time, the air transmission pipeline with large flow and low pressure should be used, and the spiral air duct is the most suitable. Generally, galvanized iron pipe is used, and stainless steel pipe is used in corrosive and particularly humid places. (2) 送冷风 (2) Cold air supply 送冷风。常见的是中央空调钢纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛的管道，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。 Send cold air. The most common is the central air-conditioning pipeline, which needs to be added with thermal insulation materials. Spiral air duct can be pasted with thermal insulation material, which looks beautiful. |
