if you want to achieve ventilation conditions indoors, you need to install ventilation pipes, and the installation of ventilation pipes and valves needs to be coordinated. How to install them correctly?

first, how to install the ventilation pipe

before installing the ventilation pipe, you need to make sufficient preparations first, and during the installation process, you also need to pay attention to some matters. First, check to see if the equipment is qualified to ensure that the surface of the air outlet is flat. There is an error, but it should be controlled within 2 mm.

next, dust the pipeline to ensure that the appearance is clean and tidy. Reserve the location and size of the holes. To assemble the air duct, it can be assembled in sections on the ground and tightened by flange bolts. The nut should be placed in the same direction above the bracket, and it should be assisted by labor and rope to adjust the verticality of the air duct.

fix it as required, and then fix the wires and so on. The two ends of each pipe section are rolled out of the drum and fastened with rivets, which can meet the requirements of ventilation and installation.

2. What should be paid attention to when cleaning ventilation pipes

1. Because ventilation pipes are made of different materials, if they are coated with color, they need to be adhered to the inner wall, and any measures should be taken, and the coating cannot be destroyed. If it is damaged accidentally, you can coat the surface with epoxy resin and carry out anti-corrosion treatment. But it can't pass through rivets, otherwise it will produce destructive power.

2. Cleaning liquid can also be used when cleaning, but it must meet the cleaning standards and be sealed in time later, otherwise it will affect the exhaust effect. Some of them are special ventilation ducts, so snap-in engagement cannot be used. To prevent longitudinal seams and gaps, it is necessary to block and seal them with sealant.

I sum up: the above is the installation method and main installation methods of ventilation pipes. You can choose circular connection, and the most important thing is to achieve sealing effect, and the pipes should be cleaned in time later.
