What is the difference between flexible duct and rigid duct?
2022-07-06
Rigid duct, also known as wall waterproof casings, are bimetallic composite duct welded by seamless duct and moisture-proof wings. Installed on concrete walls, it is used for general pipelines to pass through the wall, which is beneficial to the moisture resistance of the wall. It is suitable for pipelines that will not be damaged by pipeline vibration through the wall.
The application of flexible duct outside the pipeline can not only reduce the pipeline vibration caused by the working pressure of the internal structure of the pipeline, but also have a good moisture-proof protection effect on the pipeline and the wall. It is widely used in engineering construction, chemical plants, steel, drinking water, wastewater Processing and other enterprises.
1. The subjective difference between flexible duct and rigid duct depends on the structure and appearance. The simple structure is a rigid pipe, and the complicated structure is a flexible pipe. The two applications are different. Rigid pipelines are mainly suitable for structures that bear the working pressure and expansion deformation of pipelines. They are mainly used in the installation of wall or building wall pipelines, and are usually used in natural environments such as villa basements.

2.Flexible duct are widely used, and can be used as housing construction, engineering construction wooden floors, fire safety pools, crossing roads, reservoirs and other areas that must be fortified against earthquakes. According to the pipeline on the wall, the vibration of the pipeline can be reduced according to the rigid waterproof casing, bear the working pressure of the wall, and effectively deal with the problem of expansion and deformation of the pipeline. While maintaining the pipeline, it can also maintain the wall at a certain level to prevent the wall from cracking and falling due to pipeline vibration or water seepage. Flexible duct can be installed and applied, while rigid duct cannot be deformed.
