When the air duct conveys general gas, the black steel plate air duct shall be derusted and painted with antirust paint. The dusty gas can be sprayed with anti-wear protective layer. When the ambient air humidity is high, the outer wall of the air duct shall be treated with anti-corrosion and antirust. The inner wall of galvanized steel plate air duct conveying high temperature and high humidity gas should be sprayed with phosphating primer or other corrosion-resistant coatings. When conveying high-temperature gas or low-temperature air in the air duct, the outer wall of the air duct shall be insulated (cold). The purpose of thermal insulation of the air duct conveying high-temperature gas is to prevent the heat loss of the air in the duct (which occurs in the central air conditioning system in winter); In addition, it can prevent the heat from being radiated into the room to raise the room temperature when transporting waste heat steam or high-temperature gas, and prevent people from being scalded by contacting the air duct.

山東通風管道加工

Shandong ventilation pipe processing Co., Ltd

完善濟南通風管道加工工藝，不同的產品在加工工藝上不同，質量上也是完全不同的，真正的完善產品的加工工藝，這樣對我們來說是有很大的好處。只有你在整體的加工工藝上不斷的提升，質量上就能夠有更好的保障，這個方面對我們今后更好的使用產品來說是有大的保障的。你對這一點要真正的注意到，畢竟其真正的關系到我們今后的使用情況。

Improve the processing technology of ventilation pipes in Jinan. Different products are different in processing technology and completely different in quality. It is of great benefit to us to really improve the processing technology of products. Only if you continuously improve the overall processing technology can you have a better guarantee in terms of quality, which is a great guarantee for our better use of products in the future. You should really pay attention to this. After all, it is really related to our future use.

凈化風管的質量直接關系到系統是否達到設計參數和正常使用要求，其制作一般采用工廠集中制作和現場制作兩種方式。無論采用哪種制作方式，都要保證制作場地的潔凈和封閉，選用水泥地面或地面鋪設金屬鋼板，其面積不得小于100m²，且滿足采光和照明條件，制作完成的凈化風管要進行堆放，并進行看管;如果選用現場預制時，要保證預制完成后的風管能夠及時運施工現場，盡量減少風管搬運的距離，這樣可以避免運輸過程中對風管的污染。

The quality of purified air duct is directly related to whether the system meets the design parameters and normal use requirements. It is generally made in two ways: Factory centralized production and on-site production. No matter which manufacturing method is adopted, the manufacturing site shall be clean and closed. Cement ground or metal steel plate shall be laid on the ground, and its area shall not be less than 100m ²， And meet the daylighting and lighting conditions. The fabricated purified air duct shall be stacked and watched; If on-site prefabrication is selected, ensure that the prefabricated air duct can be transported to the construction site in time, and minimize the handling distance of the air duct, so as to avoid pollution to the air duct during transportation.
