Today, the main place where corrugation is used is, of course, the kitchen. This is where hoods are installed. Modern water heating and heating systems mainly run on gas, which requires thoughtful and reliable ventilation. The exhaust air guarantees a corrugation for drawing. It consists of durable steel rings with a special coating stretched over them. The main material in the manufacture is a laminated foil made of several layers. A well thought out design makes it possible to stretch the chimney up to three meters.
Corrugated pipe is very in 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 skill. 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 even walls, which makes the ventilation operation completely silent. However, aluminum construction is the most popular among installers and the public. She is distinguished by many positive qualities, among which are:
- high strength with any diameter of the duct;
- not subject to fire, able to 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 premises or in industrial enterprises.
- Dimensions allow the use of this design in any type of ventilation equipment.
When planning to purchase a corrugation, you should remember that the quality and durability of the ventilation system depends on the correctly selected diameter.
Currently, there are four main sizes of corrugations, with a diameter of 10; 12; 12.5; 15 centimeters. In each instruction, it is described which diameter is best suited for the installation of a ventilation system. If you install a pipe of a smaller diameter, the fan will work with considerable 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. With a long pipe, a larger fan should be installed to ensure good system operation.
What to pay attention to during installation
Corrugation for hoods 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 fasteners, which makes it possible not to spend extra money on the work. The elastic ribbed structure 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 noise during fan operation. Otherwise, the resulting folds will necessarily create a vibration, and the operation of the hood will be accompanied by increased rattling.
The corrugation is attached to the pipe of the ventilation system with the help of special metal or plastic clamps. To properly carry out installation work, you should follow the simple rules:
- If the ventilation hole is a long distance from the hood, the pipe should be laid under the ceiling. This will help to avoid sharp corners and make the system more efficient and reliable. For these purposes, it is better to use false ceilings, which ideally hide the corrugation from prying eyes;
- The diameter should be carefully selected, since a narrow duct will create a large load for the fan, which will certainly affect its operation. If the hood has a round hole, do not use a rectangular tube. This will make the work ineffective, since you will have to install special adapters that will reduce the passage of air through the duct.
How is the installation
- Before starting work, a grill with an integrated non-return valve is installed. It will help provide fresh air for ventilation when the fan is off.
- By installing an anemometer in the base of the pipe, you can determine the volume of ventilation system performance, which should be at least three kitchen volumes.
- Before mounting, check for the presence of reverse traction. To do this, attach a sheet of paper to 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 so that the design 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 purchasing a ventilation system, since the quality of the system as a whole depends on the correctly selected diameter. The diameter of the outlet must exactly match the parameters of the pipe, 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 right amount of corrugation. Then you buy the exact amount without overpaying for extra meters.
An ideal way to make a chimney, you can not worry about overheating the pipe. It is quickly and easily mounted in any type of flooring. When installing gas heating or water heating equipment, it can provide maximum outflow of combustion products, making it possible to guarantee the reliable operation of boilers and boilers. The system of such pipes has proven itself when installing fireplaces, stoves or other heating systems.
The 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 the approach to choosing corrugations, the better and longer your ventilation system will work. You should not save on a branch pipe, since the ingress of carbon monoxide into the apartment can lead to sad consequences.
