The materials of plates, profiles and other primary products used in the manufacturing of air ducts and equipment, and the planning and manufacturing of ventilation ducts should conform to the rules of the planning and the current specifications of the relevant products, and the factory inspection certificate should be used. The materials should be inspected according to the current relevant specifications when leaving the site.
The orientation, height and direction of the air duct should be well planned during the time of ventilation duct equipment. The diameter of the air duct should ensure the speed of air renewal.
The connection part of the air duct shall be tightly connected. The thickness of the gasket selected in the center shall not be less than 3mm. The gasket shall not protrude into the pipe or outside the outstanding flange. The metal air duct shall comply with strict equipment requirements when turning. Be careful not to have a dead bend or collapse when the plastic hose bends.
Before the air duct equipment, the sundries inside and outside shall be cleaned and protected. The orientation of the screws on the connecting part of the air duct should be as convenient as possible for future repair.
When the ventilation duct works, it will smoothly bring the outside fresh air into the room. For example, in daily life or under the conditions of self-defined scenes, people pass through the ventilation ducts and then ensure that some smoke or carbon monoxide in the environment is diluted through air circulation, and then do not let people be disturbed by harmful gases.
The connection method of the ventilation pipe is sensitive and diversified, because its connection method around the GRP pipe presents different characteristics, which enables it to increase the sensitivity of the pipe connection to a greater extent on the basis of the detailed construction conditions, and then advance the reliability of the project itself.
