Stainless steel ventilation pipe how to strengthen better

When we install stainless steel ventilation pipes in daily life, it is obviously installed, but it will be loose for a long time, so how should we strengthen stainless steel ventilation pipes?

1, the diameter of the circular ventilation duct is greater than or equal to 80mm, the length of the air duct is greater than 125mm or the total surface area is greater than 4㎡.

2. The side length of the rectangular ventilation duct is greater than 630mm, the side length of the insulated air duct is greater than 800mm, the length of the ventilation duct is greater than 125mm, or the side length of the low-pressure ventilation duct is greater than 1.2 square meters, and the side length of the medium-high pressure ventilation duct is greater than 1.0 square meters.

3, irregular elliptical ventilation duct reinforcement, should refer to the rectangular ventilation duct.

In addition to the reinforcement of stainless steel ventilation pipes, the following requirements should be met:

1. When the diameter or side length of the hard PVC pipe is greater than 500mm, the connection between the pipe and the flange should be equipped with a reinforcing plate, and the spacing is not greater than 450mm;

2, the reinforcement of organic glass fiber reinforced plastic and inorganic glass fiber reinforced plastic ventilation pipes should be made of main materials or materials with the same anti-corrosion properties, and combined with ventilation pipes.

In the production of stainless steel ventilation pipe bending, concentric arc bending pipe with curvature radius of one plane side length should generally be used. When other forms of elbow are used, and the plane side length is greater than 500mm, the elbow deflector should be set.
