First of all, the installation of ventilation pipes, first of all, notice that in fact it is also in the ventilation pipe assembly, in a relatively short period of time in the pipeline, to a large extent, it can also be a ground assembly, followed by pipelines for a long period of time, to a large extent, in fact, it can also be directly assembled in the ground unit according to the status of the installation site.
When the duct is assembled, the center and level of the duct should be adjusted as far as possible. To a large extent, the deformation or fluctuation of the duct can be avoided directly. In addition, it should be noted that each part of the duct should not exceed 10m. When assembling, gaskets should be flattened, flange bolts should be tightened evenly, so that the nut face faces in the same direction.
In addition, ventilation pipes, pipes in place before, to a large extent, should also pay attention to the direct inspection of water support and altitude, and then, pay attention to the degree of direct inspection should be strong legs, pipes can also use direct and disseminator, these two methods.
Then, for the ventilation duct section is relatively small, and its location is relatively low, to a large extent, in fact, the method of manual positioning can be used directly, as long as a simple scaffold can be directly set up.
Finally, let us know that the cross section of the air duct in the ventilation duct is larger and longer than that in the duct section. In fact, to a large extent, pulleys, chains or ropes can be directly used. In order to facilitate the installation of air ducts on ventilation pipes, it should be noted that air ducts should be directly suspended on scaffolding.
