通风管道是工业与民用建筑的通风与空调工程用金属或非金属管道，是为了使空气流通，降低有害气体浓度的一种市政基础设施。 风管制作与安装所用板材、型材以及其他主要成品材料，应符合设计及相关产品现行标准的规定，并应用出厂检验合格证明，材料进场时应按现行有关标准进行验收。
Ventilation pipe is a metal or nonmetal pipe for ventilation and air conditioning engineering in industrial and civil buildings. It is a municipal infrastructure for making air circulation and reducing harmful gas concentration. The plank, profile and other main materials of the production and installation of the wind pipe should conform to the national standard of the design and related products, and apply the factory inspection qualification certificate. When the materials enter the field, they should be checked according to the relevant national standards.
从冷化空调产业初始发展到现在近三十年了，净化空调用的通风管道还基本上停留在原材料原工艺的基础上，这不能不算是一种遗憾。在钢锌钢板风管的制作方面，大的公司使用机械化生产已不成问题（咬口条缝的气密性还另当别论），但保温工序如此的烦琐、安装工人如此的劳累，且质量不易保证的现状依旧没能解决。
From the initial development of the cold air conditioning industry to the recent thirty years, the ventilation pipes used for purifying the air conditioners basically remain on the basis of raw materials, which is a pity. In the steel making zinc steel sheet air pipe, production using large machinery company has no problem (airtight joint bite tongue is another matter), but the process cumbersome, so the insulation installation workers so tired, and not easy to guarantee the quality of the status quo is still not able to solve.
近年来，一种新的保温材料一橡塑材料的出现，减轻了工人的劳动强度，可还是没能摆脱其落后的劳动方式，况且这种材料目前较贵，还不能普遍使用。复合材料的出现在风管产业中是一种进步，是一种发展，复合材料是世界范围内的一种趋势，也可以说是工业进步的必然！
In recent years, a new thermal insulation material, the appearance of rubber and plastic material, has lightened the labor intensity of workers, but still can not get rid of its backward labor way. Moreover, the material is expensive at present, and it can not be widely used. The emergence of composite materials is a progress in the wind pipe industry. It is a development. Composite material is a trend in the world, which is also the necessity of industrial progress.
