众所周知，通风管道的基本用途是输送新鲜空气和废气，将有害气体排出室外，并将新鲜空气送到房间。在使用通风管道安装时需要做好防腐保温，那么有什么需要做呢？山东通风管道厂家为您介绍：

As we all know, the basic purpose of ventilation duct is to convey fresh air and waste gas, discharge harmful gases out of the room, and send fresh air to the room. When installing the ventilation pipe, it is necessary to do a good job of anti-corrosion and insulation, so what needs to be done? Shandong ventilation pipe manufacturer introduces to you:

通常使用镀锌风管，不锈钢管用于腐蚀性和特别潮湿的地方。当环境空气湿度较高时，风道外壁应进行防腐防锈处理。输送高温高湿的风道内壁应喷涂磷化底漆或其他防腐涂料。当风道输送高温气体或低温空气时，风道外壁应进行保温（冷保）处理。

Galvanized air duct is usually used, and stainless steel pipe is used in corrosive and especially humid places. When the ambient air humidity is high, the outer wall of the air duct shall be subject to anti-corrosion and anti-rust treatment. The inner wall of air duct conveying high temperature and high humidity shall be sprayed with phosphating primer or other anti-corrosion coating. When the air duct transports high-temperature gas or low-temperature air, the outer wall of the air duct shall be subject to thermal insulation (cold insulation) treatment.

输送高温气体的风道的隔热目的是防止管道中空气的热量损失（冬季出现在集中式空调系统中）。在输送废热蒸汽或高温气体时，为了防止热量传递到室内并使室温升高，可以防止人再次接触风管并烫伤。

The purpose of heat 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 centralized air conditioning system in winter). When transporting waste heat steam or high-temperature gas, in order to prevent heat transfer to the room and raise the room temperature, people can be prevented from contacting the air duct again and getting scalded.

在夏季，当输送气体的温度低于周围环境的空气露点温度时，通风管道外壁会产生冷凝现象。空调系统的空气管道会增加冷却损失，冷凝水滴会污染天花板和墙壁地板。因此，还应进行冷却和隔热处理。

In summer, when the temperature of the transported gas is lower than the ambient air dew point temperature, condensation will occur on the outer wall of the ventilation pipe. The air duct of the central air conditioning system will increase the cooling loss, and the condensate droplets will pollute the ceiling and wall floor. Therefore, cooling and heat insulation should also be carried out.

以上是通风管道防腐保温的原因。只有防腐才能减少后期使用中的腐蚀，所以我们应该注意这些方面，并尽量保证在以后使用时更光滑，效果更好。您有什么问题就来我们网站http://www.jntfgd.com咨询吧！

These are the reasons for corrosion prevention and insulation of ventilation pipes. Only corrosion prevention can reduce the corrosion in later use, so we should pay attention to these aspects and try to ensure that they are smoother and better in future use.
