1. Installation problem of air duct support and hanger
Problem analysis:
(1) The length of the main and main pipes in the ventilation pipe installation system exceeds 20m, and there is no fixed point to prevent swinging;
(2) The leakage length of the screw of the support and hanger is inconsistent.

1. Thin steel plate
Sheet steel is the main material for the manufacture of ventilation ducts and components. Plain sheet and galvanized steel are commonly used. Its specifications are expressed as short side, long side and thickness. The thickness of commonly used thin plates is 0.5×4mm, and the specifications are 900mm×1800mm and 1000mm×2000mm.

This post deals with ducted air conditioning. Below we will discuss the main points to consider when choosing the appropriate ducted air conditioning. We present the best ducted air conditioners.

The application of thermal insulation materials in the construction industry is customarily divided into two categories: inorganic matter (divided into board, block, slurry or fiber according to shape) and organic matter (including thermosetting and thermoplastic).

1. Before installation, ensure that the basic engineering has been completed
The installation of the air duct must be carried out after the completion of these basic projects; the appearance quality inspection should be carried out before installation, and the dust on the inner and outer surfaces and the sundries in the pipe should be removed.

△ Metal air duct installation requirements
(1) Air duct extension and hoisting. First of all, according to the specific conditions of the site, select two reliable hanging points on the beam and column, then hang the chain or pulley, and bind the air duct firmly with hemp rope. When lifting, when the air duct is 200~300mm above the ground, stop hoisting, carefully check the stress point of the chain or pulley and the rope binding the air duct, whether the rope buckle is firm, and whether the ce

We are living in a world where adverse climatic change has resulted to extremely high levels of global warming. These effects have not spared the mankind, animals, fish, plants, and non-living things.

In recent years, phenolic aluminum foil composite air ducts have emerged and developed rapidly, showing their talents in ventilation projects with their unique advantages. It has been applied in many important engineering buildings.

A ventilation system in a building may perform only one or a few of these tasks. Among them, the function of using ventilation to remove indoor waste heat and humidity is limited, and it is limited by the state of the outdoor air.

1. Scope of application
This construction method is applicable to the rubber and plastic insulation construction of rectangular metal air ducts in various types of air-conditioning and ventilation systems.
