pp风管在选材和连接时怎么做

How to make PP air duct in material selection and connection

pp风管在选用和连接方面需要注意哪些方面呢？很多来进行这种材料的管道安装的工程师们由于对这种新型的不太熟悉，所以有时候在选材和连接方面有时候会不知道该如何去做。

What should be paid attention to in the selection and connection of PP air duct? Many of the engineers who come to install this material are not familiar with this new type of pipe, so sometimes they don't know how to select materials and connect them.

其实在pp风管道选用时候，要考虑这种安装此类管道周围的环境，要确定温度是否在壹佰摄氏度以上，温度越高，需要选择的安全系数就要越高一些的，这样能保证使用寿命，而对于温度低于四十摄氏度的环境，要注意选择抗压能力比较***的，而且尽量选择管壁比较均匀的才***。一般在连接方面我们常常用的就是热风焊连接以及热熔对接连接，这两种连接方式在连接的过程中，温度一定要合适以及稳定，而且焊接的时候要注意保持焊接表面清洁，避免掺杂很多杂质而影响性能，***重要的是在控制温度方面尽量选择pp风管道的熔融状态，不要有烧焦的情况才***，在焊接的时候也要注意连接的两个本体不要存在缝隙。

In fact, when selecting PP air duct, we should consider the surrounding environment of the installation of such duct, and determine whether the temperature is more than one hundred degrees Celsius. The higher the temperature is, the higher the safety factor to be selected will be, so as to ensure the service life. For the environment with the temperature lower than forty degrees Celsius, we should pay attention to the selection of the one with better compressive capacity, and try to choose the pipe wall ratio It's better to be more even. In general, we often use hot-air welding connection and hot-melt butt connection in connection. In the process of connection, the temperature must be appropriate and stable. In addition, when welding, we should pay attention to keep the welding surface clean and avoid the influence of many impurities on the performance. The most important thing is to try to choose the melting state of PP air pipe in terms of temperature control It's better to have scorching condition. When welding, it's also necessary to pay attention to that there is no gap between the two connected bodies.
