Although metal conduit is easy to use, the following three points should be paid special attention to during installation:
First, the device circuit shall be designed in advance and a reasonable device scheme shall be formulated to improve the efficiency and quality of the device. The second is to prepare sufficient metal threading pipes, device accessories and props, and use these accessories and tools when installing to ensure the effect of the device. For example, the number of hanger, suspender, and joint used when fixing. Third, in the process of installation, it is necessary to monitor the effect of the device in real time to ensure that the metal conduit is installed according to the planned line and quality requirements, so as to prevent rework and other conditions.
