Today, the main place where corrugation is used is, of course, the kitchen. This is where the hoods are installed. Modern water heating and heating systems are mainly gas-fired, which requires sophisticated and reliable ventilation. The extraction of the exhaust air is guaranteed by the corrugation for the hood. It consists of durable steel rings with a special coating stretched over them. The main material for manufacturing is laminated foil, made of several layers. A well thought-out design makes it possible to stretch the chimney up to three meters.
The corrugated pipe is in great demand, especially when installing ventilation systems in hard-to-reach places. Due to its versatility, installation can be carried out by a specialist of any qualification. The diameter in each case is selected individually and directly depends on the equipment to which the corrugation is connected. Modern industry produces two main types of corrugated pipes:
- Plastic.
- Aluminum.
The PVC product has no ribs and is a smooth pipe with completely flat walls, which makes the ventilation operation completely silent. However, the aluminum construction is the most popular among installers and the general public. It has many positive qualities, among which are:
- high strength for any diameter of the duct;
- not subject to fire, can easily withstand high temperatures;
- excellent aerodynamics.
Technical specifications
- The corrugated pipe is able to work perfectly in a high temperature range from -30 to +250 degrees Celsius.
- It can be used in any type of hood in residential buildings or industrial plants.
- The dimensions allow this design to be used in any kind of ventilation equipment.
When planning to purchase corrugation, it should be remembered that the quality and durability of the ventilation system depends on the correct diameter.
Currently, four main corrugation sizes are produced, with a diameter of 10; 12; 12.5; 15 centimeters. Each manual describes which diameter is optimal for the installation of the ventilation system. If you install a pipe with a smaller diameter, the fan will work with significant effort and can quickly fail.
There are no restrictions on the length of the corrugation, it all depends on the distance between the fan and the exhaust air outlet. When choosing a corrugation, it should be remembered that the more bends and the longer the path to the outlet, the less productive the ventilation will be. If the pipe is long, a larger fan should be installed to ensure good system performance.
What to look for during installation
The corrugation for the hood is considered ideal if it is completely hidden in a wall cabinet. The work is carried out without the use of special adapters and complex fastening elements, which makes it possible not to spend extra money on work. Elastic ribbed design easily bends around obstacles, which eliminates the need for additional connections and fittings. Before starting work, the corrugation is fully stretched and installed in such a way that reduces the noise during the fan operation. Otherwise, the resulting folds will certainly create vibration, and the operation of the hood will be accompanied by increased rattling.
The corrugation is attached to the ventilation system branch pipe using special metal or plastic clamps.To carry out the installation work correctly, you should adhere to simple rules:
- If the ventilation opening is at a great distance from the hood, the pipe should be run under the ceiling. This will help avoid sharp corners and make the system more efficient and reliable. For these purposes, it is better to use suspended ceilings, which ideally hide the corrugation from prying eyes;
- the diameter should be carefully selected, since a narrow air duct will create a large load on the fan, which will certainly affect its operation. If the hood has a circular opening, do not use rectangular pipe. This will make the work ineffective, since you will have to install special adapters that will reduce the passage of air through the duct channel.
How is the installation carried out
- Before starting work, a grill with a built-in check valve is installed. It will help to ensure the supply of fresh air to ventilate the room when the fan is off.
- By installing an anemometer in the base of the pipe, you can determine the volume of the ventilation system, which should be at least three volumes of the kitchen.
- Before installation, check for backdraft to do this, attach a sheet of paper to the grille of the hood, it should adhere tightly to the hole. The presence of backdraft can reduce the effectiveness of the forced ventilation system.
- During installation, you should try to ensure that the structure has as few bends and turns as possible, since this reduces the efficiency of work many times.
The choice of the duct is made after the purchase of the ventilation system, since the quality of the system as a whole depends on the correctly selected diameter. The outlet diameter must be exactly matched to the parameters of the pipe, this is the only way to achieve maximum efficiency.
Often, trading organizations, along with the hood, offer a corrugated pipe in the kit. You can refuse the imposed service if you read the instructions in a timely manner and calculate the required amount of corrugation. Then you will buy the exact amount without overpaying for extra meters.
An ideal way to make a chimney, you don't have to worry about overheating of the pipe. It can be quickly and easily installed in any type of floor. When installing gas heating or water heating equipment, it can ensure the maximum outflow of combustion products, making it possible to guarantee the reliability of the operation of boilers and boilers. A system of such pipes has proven itself well when installing fireplaces, stoves or other heating systems.
Steel inner frame and heavy-duty film allow you not to worry about the durability and reliability of the structure. Remember that the more responsible you are when choosing corrugations, the better and longer your ventilation system will work. You should not save on a drain pipe, since the ingress of carbon monoxide into an apartment can lead to sad consequences.
