Assembly and installation of air ducts

Begin the installation of air ducts with pre-assembled fittings and straight sections in the enlarged units. Individual parts and links of air ducts, as a rule, are assembled with the help of folding, flanges or without flange connections.

Duct network installation

In industrial ventilation installation works must be carried out only after the main finishing works (plastered walls, ceilings and partitions) have been made in the places of air ducts laying and technological equipment that sucks air in the system called "exhaust ventilation" is installed . Air ducts, their installation, in some individual cases can be produced without technological equipment. It all depends on the situation. After the installation of ductwork has been completed, it is strictly forbidden to perform construction or other work. They can damage the ventilation network.

Before starting the installation of ventilation and air ducts, it is necessary to carefully check the feasibility of the project under the project, to be able to lay this system, preparedness and compatibility of the mounting bearings of engines, calorifers, fans and so on with foundation drawings, setting up industrial equipment for the project. Connection of receivers, umbrellas and air ducts to it.

If there are deviations from the project in the process, they must be coordinated with technical supervision or design organization. The place of installation works should be not only free, but also accessible for carrying out works. Laying a line of air ducts from parts and finished manned units can be done by columns and walls of the building, under the ceiling, in underground channels and even at the floor. To ensure that the ducts do not interfere with the production process, they must be laid under the ceiling of the room.

Air ducts are suspended on yokes and special pendants to beams, ceilings and farms, and on brackets - along walls and columns. Brackets and clamps are made exactly by the size of the air ducts. At the height of the installation of air ducts and other equipment is carried out with scaffolding. Can be used and forests. And when it is necessary to perform the installation of air ducts, instead of special scaffolds and scaffolds, it is possible to use inventory mounting pads that make it possible to significantly reduce the assembly and disassembly of forests to fifty percent of the working time.

All the assembled line of ventilation and air ducts must necessarily have a beautiful appearance. In no case is the curvature of the air ducts, appreciable dents, flanges that are not perpendicular to the duct, long ends of the clamps that protrude outward. Do not have large gaps and sit tightly on the duct system all the flanges. Goffers or assemblies should not be in places where flanges are fitted.

And only when the brigade installers will fulfill the above requirements, fresh air in the room will come without interruptions.
