How to make PP air duct in material selection and connection
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.
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.
