Plastic ducts - types and applications

The ventilation of the premises of any building is made with the help of air ducts. They are pipes that allow air to enter the rooms. They are made of steel, aluminum, plastic. Plastic ducts appeared in operation not so long ago. This material is plastic and inexpensive. They can easily replace metal structures. In addition, they have a number of advantages before them. Plastic ducts are easy to operate and install. They have ample strength with a lighter weight. And besides, they are cheaper. In addition, they are resistant to corrosion, they can be installed in a room with high humidity. Resistant to the effects of acids and alkalis, which allows them to be used in the premises of electroplating plants, in chemical industries, in the premises of the pharmaceutical and food industries. Plastic duct does not emit harmful substances and is not harmful to human health. It is often used to make ventilation in buildings with a large number of people. Air ducts make ventilation more silent and intense due to their smooth surface. To prevent dust from gathering on them, they are treated with an antistatic compound. And the transportation of such structures is more convenient. But these ducts also have their disadvantages. And, perhaps, the main one is the plasticity of the fuel.

Rectangular constructions

Especially often used in industrial and residential premises ducts are plastic rectangular. They are easier to install, because their shape makes it easy to attach parts to the ceiling and walls or to rest on other surfaces. Especially they are indispensable for installation in difficult conditions or in the case when the cross-sectional area is too large. The structures of this form are especially convenient when they are attached under suspended ceilings. There are such ducts of rectangular shape, in which the height is four times smaller than the width. Such constructions are called flat. They are collected manually. Their disadvantage is that they are considered to be noisier and more resistant to the flow of air. For such structures, sometimes it is required to purchase additional equipment (for example, fans, sound absorbers).

Ventilation from polypropylene

Correctly executed ventilation in the house is one of the main factors of comfortable living. A bad system will quickly let you know about yourself with high humidity, smells, a touch of fat in the kitchen. In the living quarters the ventilation system made by plastic ducts will be very good. For these purposes, polyethylene, polypropylene, polyurethane, PVC, silicone and a number of other synthetic materials are used. Ventilating structures made of polypropylene are waterproof, wear-resistant, resistant to aggressive chemical environment, to ultraviolet radiation. Have a service life of 50 years. Withstands a temperature range from -40 to + 85 ° C. But the kitchen is best suited ducts made of PVC made of PVC. PVC is a very versatile material and has better plastic properties. From other materials it is distinguished by a long service life - up to 100 years, and high hygiene.
