在安装通风蜜桃APP下载网站时，还必须按照规定的要求采取加固措施，，下面来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、环形蜜桃APP下载网站的加固：环形蜜桃APP下载网站本身强度高，蜜桃APP下载网站两端的法兰起到一定的加固作用。圆形蜜桃APP下载网站直径大于800mm或等效大于800mm，管段长度大于1250mm或管段总表面积大于4m2，防止运输。或者在吊装过程中咬口裂开。当圆管直径大于500mm时，纵向咬合两端用铆钉或点焊固定。

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、矩形风管的加固：与圆形风管相比，矩形风管强度较低，容易变形。矩形蜜桃APP下载网站长边大于630mm，保温蜜桃APP下载网站长边大于800mm，管段长度大于1250mm，或低压一侧的平坦区域蜜桃APP下载网站1.2m2以上，中高压蜜桃APP下载网站1.0m2以上，为减少中压蜜桃APP下载网站运输和安装变形，生产中采取了强化措施

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

通风管防火护套不锈钢通风管的实践

Practice of stainless steel vent pipe with fireproof sheath for vent pipe

1、管材不耐火，但可能会遇火。例如，在加热器附近安装PVC材质的通风蜜桃APP下载网站时，需要进行防火处理。

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、蜜桃APP下载网站输送的气体易燃易爆时，需要防火包装。比如正压蜜桃APP下载网站输送机有油烟、废气时，防火包会延长通风蜜桃APP下载网站的耐受时间，防止蜜桃APP下载网站被烧毁，大量气体溢出引起爆燃。

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、蜜桃APP下载网站输送的气体对温度敏感时，气体成分可能对温度敏感，容易发生温度变性。这时不仅要进行恒温处理，还要进行防火处理，以免发生意外。

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、蜜桃APP下载网站暴露于高温易燃环境时，一般需要进行防火处理。除了餐厅炉灶顶部的排气管是由铁皮制成的，它通常会燃烧火焰。

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.

山东通风蜜桃APP下载网站加工厂家认为通过风管安装时，必须严格按照图纸进行施工。正式施工前，必须制定工期，提前制定施工计划，及时为工人打好技术基础。此外，蜜桃APP下载网站安装施工除了自己的工作外，还需要与土木工程协调，避免交叉作业对蜜桃APP下载网站施工造成的不便和影响。

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.
