Jinan ventilation duct can make air convection, discharge dirty or harmful gas, dilute and recycle air in our relatively closed environment, make outdoor air and indoor air convection, and improve indoor air quality. The second is to facilitate the emission of some harmful gases, which will not cause secondary air pollution to some harmful gases, and have planned air emission areas.

那么，目前的通风管道技术相对灵活，不会影响我们美丽的环境，可以根据不同环境的不同要求进行设计、施工和安装，从而提高我们对效果的要求。

Then, the current ventilation duct technology is relatively flexible, will not affect our beautiful environment, can be designed, constructed and installed according to the different requirements of different environments, so as to improve our requirements for the effect.

通风管道设备有自己的材料、板材、型材等成品，在生产加工前必须经过仔细的测试。指标数据必须符合规定的数值，并能用于设备生产和建设。通风管道可分为普通钢管、镀锌风管、彩钢夹层保温通风管道等。

Ventilation duct equipment has its own professional materials, plates, profiles and other finished products, which must be carefully tested before production and processing. The index data must conform to the value stipulated by the state and can be used for equipment production and construction. Ventilation duct can be divided into ordinary steel pipe, galvanized air duct, color steel sandwich insulation ventilation duct, etc.

它们都有自己的功能。通风管道设备一般用于通风和系统的各个领域。随着科技的发展，通风管道设备的样式也有了空间选择，如普通的圆形、矩形、仍然螺旋形等。选择范围后，企业可以根据自己的通风需求，并选择合适的通风系统进行安装。如果我们想在加工通风管道时提高质量，就要选择好材料。好的材料能生产出高质量的产品，而坏的材料不能达到产品质量，这实际上对我们来说非常关键。通过在加工过程中选择好的材料来实现加工，才是有好处的。

They all have their own functions. Ventilation duct equipment is generally used in various fields of ventilation and environmental protection system. With the development of science and technology, there are also space choices for the style of ventilation duct equipment, such as ordinary circular, rectangular, still spiral, etc. After selecting the range, enterprises can choose the appropriate ventilation system according to their own ventilation requirements. If we want to improve the quality of the processing of ventilation ducts, we must choose good materials. Good materials can produce high-quality products, but bad materials can't achieve product quality, which is actually very important for us. It is beneficial to select good materials in the processing process to realize processing.
