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，目前的通風管道技術相對靈活，不會影響我們美麗的環境，可以根據不同環境的不同要求進行設計、施工和安裝，從而提高我們對效果的要求。

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.

通風管道設備有自己的材料、板材、型材等成品，在生產加工前必須經過仔細的測試。指標數據必須符合國家規定的數值，并能用于設備生產和建設。通風管道可分為普通鋼管、鍍鋅風管、彩鋼夾層保溫通風管道等。

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.

它們都有自己的功能。通風管道設備一般用于通風和環保系統的各個領域。隨著科技的發展，通風管道設備的樣式也有了空間選擇，如普通的圓形、矩形、仍然螺旋形等。選擇范圍后，企業可以根據自己的通風需求，并選擇合適的通風系統進行安裝。如果我們想在加工通風管道時提高質量，就要選擇好材料。好的材料能生產出高質量的產品，而壞的材料不能達到產品質量，這實際上對我們來說非常關鍵。通過在加工過程中選擇好的材料來實現加工，才是有好處的。

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.
