　　The inner wall of the ventilation pipe is smooth, the resistance is small, the ventilation loss is small, the energy consumption is low, the operation cost is saved, the air tightness and sealing are good, and the pressure and compressive strength are high.

　　不銹鋼管的設備主要是為了讓它通風和通風功能的使用,為了達到這個目的,需要選擇一些好的材料初規劃設備進行處理,并結合這些因素和特點的總結和分析,為了更好地展示其性能。

　　The equipment of stainless steel pipe is mainly for its ventilation and use of ventilation function. In order to achieve this purpose, it is necessary to select some good materials for preliminary planning equipment for treatment, and combine the summary and analysis of these factors and characteristics, in order to better show its performance.

　　不銹鋼風道保溫材料應平鋪，法蘭保溫材料與風道本身選用相同的保溫材料，風道與法蘭間距應在7mm左右，并保證兩個方向之間的接觸。

　　The insulation material of stainless steel air duct shall be laid horizontally. The same insulation material shall be selected for the flange insulation material and the air duct itself. The distance between the air duct and the flange shall be about 7mm, and the contact between the two directions shall be ensured.

　　在施工過程中，還要注意施工進度和總工期，這也是一個非常重要的內容。只有充分掌握這一部分，我們才能對這個項目和其他部分有一個很好的了解。我們需要熟悉管道加工的各個方面，這樣我們才能更好地操作。

　　In the process of construction, we should pay attention to the construction progress and the total construction period, which is also a very important content. Only by fully mastering this part can we have a good understanding of this project and other parts. We need to be familiar with all aspects of pipe processing so that we can operate better.

　　風口表面光滑、色彩和諧、安裝方法和效果是合理的,柔軟的驗收應同意規劃標準,操作應該是強大的,自然的,風扇,風機盤管,有必要加強有用,如原材料和絕緣層的厚度應該滿意的規劃要求,外觀應整潔,無裂紋,涂層的不銹鋼管應該是優異的附著力,厚度和厚度不應脫落。

　　The surface of the tuyere is smooth, the color is harmonious, the installation method and effect are reasonable, the soft acceptance should agree with the planning standard, the operation should be strong and natural, the fan, fan coil, it is necessary to strengthen the useful, such as the thickness of the raw materials and insulation layer should meet the planning requirements, the appearance should be clean and free of cracks, the coated stainless steel pipe should be excellent adhesion, the thickness and thickness should not fall off.

　　不銹鋼焊接管道是現在很常見的設備，它的加固實際上是規定和要求的，你知道嗎?以下是不銹鋼焊管的生產廠家。

　　Stainless steel welded pipe is a very common equipment now, its reinforcement is actually specified and required, do you know? The following is the manufacturer of stainless steel welded pipe.

　　1. 如果使用管道支架，支撐點與管道邊緣或法蘭之間的間距應均勻，且其值不應大于950毫米。

　　1. If a pipe support is used, the distance between the support point and the edge or flange of the pipe shall be uniform and the value shall not be greater than 950mm.

　　2. 補強或補強時，補強布置要規范，補強間距要均勻。另外，對于板材表面，不應出現明顯的變形等。

　　2. For reinforcement or reinforcement, the reinforcement arrangement shall be standardized and the reinforcement spacing shall be uniform. In addition, there should be no obvious deformation on the plate surface.

　　3.焊接管道的加固應采用鋼筋、立筋、角鋼、扁鋼、鋼筋、管架等，可根據實際情況和需要進行選擇。

　　3. The reinforcement of welded pipeline shall adopt reinforcement, vertical reinforcement, angle steel, flat steel, reinforcement, pipe support, etc., which can be selected according to the actual situation and needs.

　　4. 使用角鋼或鋼筋時，還應整齊、均勻、對稱布置。高度不應大于法蘭寬度。

　　4. When angle steel or reinforcement is used, it shall be arranged orderly, evenly and symmetrically. The height shall not be greater than the flange width.
