在安裝通風管道時，還必須按照規(guī)定的要求采取加固措施，，下面來整理了一番了解下吧。
When installing the ventilation duct, reinforcement measures must be taken according to the specified requirements. Let's have a look at it.
1、環(huán)形管道的加固：環(huán)形管道本身強度高，管道兩端的法蘭起到一定的加固作用。圓形管道直徑大于800mm或等效大于800mm，管段長度大于1250mm或管段總表面積大于4m2，防止運輸。或者在吊裝過程中咬口裂開。當圓管直徑大于500mm時，縱向咬合兩端用鉚釘或點焊固定。
1. Reinforcement of annular pipeline: the annular pipeline has high strength, and the flanges at both ends of the pipeline play a certain role in reinforcement. The diameter of circular pipe is greater than 800mm or equivalent greater than 800mm, the length of pipe section is greater than 1250mm or the total surface area of pipe section is greater than 4m2 to prevent transportation. Or the bite cracks during hoisting. When the diameter of the round pipe is greater than 500mm, both ends of the longitudinal bite shall be fixed with rivets or spot welding.
2、矩形風管的加固：與圓形風管相比，矩形風管強度較低，容易變形。矩形管道長邊大于630mm，保溫管道長邊大于800mm，管段長度大于1250mm，或低壓一側的平坦區(qū)域管道1.2m2以上，中高壓管道1.0m2以上，為減少中壓管道運輸和安裝變形，生產中采取了強化措施
2. Reinforcement of rectangular air duct: compared with circular air duct, rectangular air duct has lower strength and is easy to deform. The long side of the rectangular pipeline is greater than 630mm, the long side of the insulation pipeline is greater than 800mm, the length of the pipe section is greater than 1250mm, or the pipeline in the flat area on the low-pressure side is more than 1.2m2, and the medium and high-pressure pipeline is more than 1.0m2. In order to reduce the transportation and installation deformation of the medium pressure pipeline, strengthening measures have been taken in production
通風管防火護套不銹鋼通風管的實踐
Practice of stainless steel vent pipe with fireproof sheath for vent pipe
1、管材不耐火，但可能會遇火。例如，在加熱器附近安裝PVC材質的通風管道時，需要進行防火處理。
1. The pipe is not fire-resistant, but may encounter fire. For example, when installing PVC ventilation pipes near the heater, fire protection treatment is required.
2、管道輸送的氣體易燃易爆時，需要防火包裝。比如正壓管道輸送機有油煙、廢氣時，防火包會延長通風管道的耐受時間，防止管道被燒毀，大量氣體溢出引起爆燃。
2. When the gas transported by pipeline is flammable and explosive, it needs fire-proof packaging. For example, when there is oil smoke and waste gas in the positive pressure pipeline conveyor, the fire bag will extend the withstand time of the ventilation pipeline to prevent the pipeline from being burned and a large amount of gas from overflowing to cause deflagration.
3、管道輸送的氣體對溫度敏感時，氣體成分可能對溫度敏感，容易發(fā)生溫度變性。這時不僅要進行恒溫處理，還要進行防火處理，以免發(fā)生意外。
3. When the gas transported by the pipeline is sensitive to temperature, the gas composition may be sensitive to temperature and is prone to temperature denaturation. At this time, not only constant temperature treatment but also fire prevention treatment shall be carried out to avoid accidents.
4、管道暴露于高溫易燃環(huán)境時，一般需要進行防火處理。除了餐廳爐灶頂部的排氣管是由鐵皮制成的，它通常會燃燒火焰。
4. When the pipeline is exposed to high temperature and flammable environment, it is generally required to carry out fire prevention treatment. Except for the exhaust pipe on the top of the restaurant stove, which is made of iron sheet, it usually burns a flame.
山東通風管道加工廠家認為通過風管安裝時，必須嚴格按照圖紙進行施工。正式施工前，必須制定工期，提前制定施工計劃，及時為工人打好技術基礎。此外，管道安裝施工除了自己的工作外，還需要與土木工程協(xié)調，避免交叉作業(yè)對管道施工造成的不便和影響。
Shandong ventilation duct manufacturer believes that the construction must be carried out in strict accordance with the drawings when installing the air duct. Before the formal construction, the construction period must be formulated, and the construction plan must be formulated in advance to lay a good technical foundation for workers in time. In addition, in addition to their own work, the pipeline installation and construction also need to coordinate with the civil engineering discipline to avoid the inconvenience and impact of cross operation on the pipeline construction.
