A well-equipped ventilation system is the key to a comfortable stay in the house. Therefore, it is difficult to imagine a kitchen without a hood with corrugation. The ventilation duct removes steam, unpleasant odors and combustion products that are released during cooking from the room. As you know, without exhaust, all fat deposits would remain indoors and settle on kitchen furniture, household appliances and walls. The information given in the article will allow you to correctly choose and install the corrugation for hoods to a potential buyer.
What is corrugation?
Corrugated pipes are used as ducts, thanks to which all combustion products, various fumes that appeared after cooking the food come out of the room. The diameter of the corrugation for the hood is different, they make products from a variety of materials, they also have different lengths. For the manufacture of pipes in production using stainless steel, galvanized steel and aluminum. The cross section of the design for the outlet is round and square in shape, and is selected under the neck of the hood and ventilation channel.
The exhaust system prevents the spread of unpleasant odors around the house, therefore, to ventilate the room, there is no need to open windows and doors.
Before buying a corrugated pipe, you should familiarize yourself with its properties and features. Products are flexible, able to withstand bending, returning to their original appearance, and semi-flexible. The main characteristics of corrugated pipes include:
- resistance to high temperatures;
- bending value;
- product diameter.
Flexible corrugated pipes are heat-insulated, it suppresses the noise level.
Types of corrugated pipes
For home hoods, two types of corrugation are used:
- Aluminum corrugation for hoods. Such designs are most common because they are inexpensive and versatile. Products are characterized by anticorrosion properties and a long service life, and they are not afraid of high temperatures.
- Corrugated plastic pipe. Plastic products have the same purpose as aluminum corrugations. They harmoniously fit into the interior of the room, but unfortunately, plastic pipes are unstable to high temperatures.
The main elements of ventilation systems
To determine exactly which ventilation system is best suited, you need to familiarize yourself with the basic structural elements:
- Connectors They are equivalent and transitional. It is the adapter connectors that are used to mount the ventilation pipes.
- The non-return valve is used to ensure that the air flows correctly.
- Details for fastening. Accelerate the laying of corrugated pipes.
- Bends or turns. Used to direct the structure in the right direction.
- Air duct It is selected based on the parameters of the section and the pipe itself. The standard parameters of the corrugations for the hood are 120 by 60 millimeters.
When selecting parts for construction, it is necessary to take into account the dimensions of the product itself.
Advantages and disadvantages
Corrugated pipe has certain advantages and disadvantages. The advantages include:
- Simple installation. The corrugation for the hood bends perfectly, so it is easy to install it yourself.
- A large assortment.
- It has a long service life.
- Affordable prices for every person.
Disadvantages of corrugated pipe:
- Since the structures are too light, they can be damaged during installation.
- Corrugation needs to be mounted carefully, the rectified duct is difficult to fold back.
- The presence of corrugated folds complicates the washing of the structure.
Corrugated Pipe Diameter
The diameter of the structure is of great importance, since even the smallest error will reduce performance, will lead to additional resistance. Most often, consumers prefer a round plastic corrugation for hoods, 150 mm in diameter. Pipes with such a diameter are easy to install and have a long enough service life. Second place in sales is taken by a 100 mm corrugated pipe. And in last place is a pipe for hoods with a diameter of 120 millimeters, the most slow-moving.
In industry, pipes with a diameter of 200 millimeters are always used. The large size of the product is ideal for exhausting smoke and removing contaminated air, especially in chemical laboratories.
How to choose a pipe?
A wide range of corrugated pipes makes it difficult to buy the right option. When choosing a product, first of all pay attention to some parameters.
- What the pipe is made of.
- Diameter and height of the structure. In the construction shops of Leroy, a consultant will help you choose the corrugation for drawing the required diameter.
- Quality.
- Cost.
If the diameter of the corrugation for the hood is larger than the pipe of the hood itself, this can lead to breakdown of expensive equipment. It is worth paying attention to the products of this company, because according to customer reviews, corrugated pipes are of high quality, and the company itself has earned an excellent reputation in the market.
When choosing, consider the place of operation, that is, its features. If the pipe needs to be installed on the street, then it is better to choose a product with thermal insulation.
Since the corrugated pipe must fit into the general environment of the room, special attention must be paid to the color of the material.
When buying corrugation, you should make sure that the product is of high quality and certified. If scratches or other defects were noticed on the product during inspection, it is better not to buy it.
Installation and installation of corrugated pipe
When installing a corrugated pipe, special attention must be paid to the following points:
- Quality and reliability of fastening. The corrugation life for the hood depends on the fastening. In order for the product to hold well, it must be fastened every 2 meters, and if the structure is short, it is better through a meter. All joints on the pipe must be fixed.
- Tightness. If cracks appear at the joints, then all the unpleasant odor that should go outside will fall back into the room.
- The presence of a fan. Proper installation of the fan contributes to the correct discharge of air.
Starting installation, it is necessary to prepare materials for installation, namely:
- clamp;
- aluminum tape;
- flexible tube;
- sealant;
- grill with valve.
In addition, you will need an adapter, but only if the exhaust pipe and corrugation are of different shapes or differ in diameter. Buy all the parts together, it will be easier to choose the number of elements needed for installation.
Steps for mounting the open part of the hood
When all the materials have been prepared, you can begin installing the corrugation. The process consists of the following steps:
- First you need to stretch the pipe and attach the end to the exhaust pipe.
- To ensure that the duct fixes correctly, clamps must be put in every one and a half meters.
- Next, connect the other end to the ventilation hole and treat the joints with sealant.
When is it necessary to change pipes?
In residential premises, stainless steel and aluminum products are most often used. Corrugation for drawing is resistant to moisture, it does not rot and does not lend itself to corrosion, so it is used most often. The service life of a corrugated pipe depends on proper installation, careful and regular care of the product.
It is not necessary to take special care of the corrugation, it will be enough to wipe the dust and soot from time to time. Despite regular cleaning, a thick greasy coating with particles of dust and burning will form on the corrugation walls over time. Unfortunately, it is impossible to clean up such severe pollution, so the only way out is to buy a new pipe. When removing the old corrugated pipe, it is necessary to clean the joints, the grille on the ventilation and only then install the new corrugation.
Disguise options
In addition to its main purpose, the corrugated pipe should aesthetically look and fit into the interior of the room. If the ventilation pipe has a rectangular cross-section, then it must be masked by hanging over the kitchen cabinets. There are kitchen sets that have a special place designed for plastic ventilation pipes. For disguise most often use:
- a box of drywall or plastic;
- suspended or suspended ceiling.
Then the corrugation for the hood looks more presentable.
These masking options facilitate unhindered and quick access to all communications. If the hood and ventilation pipes have the same color, then you do not need to mask them, the main thing is to correctly enter the structure into the interior of the room.
In Leroy Merlin construction hypermarkets, it’s easy to pick up a variety of parts for the corrugation for hoods, that is, to complete the product. All structural elements are of high quality and technical characteristics, and the need to search for and purchase fasteners or other parts will disappear, which is advantageous in material terms and in the temporary aspect.
Corrugated Pipe Care
The corrugation with smooth walls can be easily and unhindered to clean from pollution. It is easy to care for a structure consisting of sections, and products with a diameter of corrugation for drawing 120 millimeters are easy to clean by putting your hand with a sponge inward. Sections are easily removed and installed.
When the walls of the corrugation are embossed, it is more difficult to clean the dirt. It is in the folds during the operational period that dirt, dust and fat deposits accumulate. Because of this, many homeowners do not spend time cleaning, but buy a new pipe.
Having familiarized yourself with the installation features and the rules for choosing the corrugation, you can easily carry out all the work yourself. The installation process does not require special skills; during installation, you can do without professional tools. A neatly and properly installed corrugated pipe will serve for many years.
