A well-equipped ventilation system is the key to a comfortable stay in the house. Therefore, it is hard to imagine a kitchen without a corrugated hood. The ventilation duct removes steam, unpleasant odors and combustion products from the room that are released during cooking. As you know, without the hood, all fat deposits would remain indoors and settle on kitchen furniture, household appliances and walls. The information provided in the article will allow a potential buyer to correctly select and install a corrugated hood for a potential buyer.
What is corrugation?
Corrugated pipes are used as air ducts, thanks to which all combustion products, various fumes that appear after cooking, exit the room. The diameter of the corrugations for the hood is different, products are made from a variety of materials, and they also have different lengths. For the manufacture of pipes in production, stainless steel, galvanized steel and aluminum are used. The cross section of the structure for the outlet is round and square, and is selected under the neck of the hood and the ventilation channel.
The exhaust system prevents the spread of unpleasant odors around the house, therefore, in order toventilate 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 form, and semi-flexible. The main characteristics of corrugated pipes include:
- high temperature resistant;
- bend amount;
- product diameter.
Flexible corrugated pipes are thermally insulated to suppress noise.
Types of corrugated pipes
For home hoods, two types of corrugations are used:
- Aluminum corrugation for the hood. Such designs are most common because they are inexpensive and versatile. The products have anti-corrosion properties and a long service life, as well as they are not afraid of high temperatures.
- Plastic corrugated pipe. Plastic products have the same purpose as aluminum corrugations. They harmoniously fit into the interior of the room, but unfortunately, plastic pipes are not resistant to high temperatures.
Main elements of ventilation systems
To determine exactly which ventilation system is best suited, you need to familiarize yourself with the basic design elements:
- Connectors. They are equivalent and transitional. It is the adapter connectors that are used to attach the ventilation pipes.
- The check valve is used to ensure that the air flows correctlymoving around.
- Details for fastening. Accelerate the laying of corrugated pipes.
- Bends or twists. Used to guide the structure in the right direction.
- Air duct. It is chosen based on the parameters of the section and the pipe itself. Standard parameters of corrugation sections for hood － 120 by 60 millimeters.
When selecting parts for the construction of a structure, 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:
- Easy installation. The corrugation for the hood bends perfectly, so it is easy to install it yourself.
- Large assortment.
- Has a long service life.
- Affordable prices for everyone.
Disadvantages of corrugated pipe:
- Because the structures are too light, they can be damaged during installation.
- Mount the corrugation carefully, it is difficult to fold the straightened air duct 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 and lead to additional resistance. Most often, consumers prefer a round plastic corrugation for hoods, 150 mm in diameter. Rolled pipes with such a diameter are easy to install and have a fairly longoperational period. The second place in sales is occupied by 100 mm corrugated pipe. And in last place is a pipe for an exhaust with a diameter of 120 millimeters, the most slow.
In industry, pipes with a diameter of 200 millimeters are always used. The large size of the product is ideal for fume extraction and contaminated air removal, especially in chemical laboratories.
How to choose the right pipe?
The wide range of corrugated pipes makes it difficult to find 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 Leroy construction stores, a consultant will help you choose a corrugation for extracting the required diameter.
- Quality.
- Cost.
If the diameter of the corrugation for the hood is larger than the nozzle of the hood itself, this can lead to damage to 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 outdoors, it is better to choose a product with thermal insulation.
Because the corrugated pipe must fit into the overall environment of the room, special attention must be paid to the color of the material.
When buying a corrugation, you should make sure that the goodsquality 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 service life of the corrugation for the hood depends on the fastening. In order for the product to hold well, it must be fixed every 2 meters, and if the design is short, then it is better after a meter. All joints on the pipe must be fixed.
- Tightness. If gaps 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 release of air.
Starting installation, you need to prepare materials for installation, namely:
- collar;
- aluminum tape;
- flexible tube;
- sealant;
- grille 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, so it will be easier to choose the number of elements required for installation.
Steps of installation of the open part of the hood
When all the materials are prepared, you can start installing the corrugations. The process consists of the following steps:
- First, the pipe must be stretched andattach the end to the hood nozzle.
- In order for the air duct to be fixed correctly, clamps must be installed every one and a half meters.
- Next, connect the other end to the vent and seal the joints with sealant.
When should pipes be changed?
In residential premises, stainless steel and aluminum products are most often used. The corrugation for the hood is resistant to moisture, it does not rot and does not corrode, so it is used most often. The service life of a corrugated pipe depends on proper installation, careful and regular maintenance of the product.
You don’t need to take special care of the corrugation, it will be enough to wipe dust and soot from time to time. Despite regular cleaning, over time, a thick fatty coating with particles of dust and burning will form on the walls of the corrugation. Unfortunately, it is impossible to clean such strong 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 ventilation grate and only then mount the new corrugation.
Disguise options
In addition to its main purpose, the corrugated pipe should look aesthetically pleasing 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 kitchen cabinets. There are kitchen sets that have a special place designed for plastic ventilation pipes. Most often used for disguise:
- gypsum board or plastic box;
- stretch or false ceiling.
Then the corrugation for the hood looks more presentable.
These masking options contribute to unhindered and quick access to all communications. If the hood and ventilation pipes have the same color, then there is no need to mask them, the main thing is to correctly fit the structure into the interior of the room.
In Leroy Merlin building hypermarkets, it is not difficult to pick up a variety of details for the corrugation for the hood, that is, to complete the product. All structural elements are of high quality and technical characteristics, and the need to search and purchase fasteners or other parts will disappear, which is beneficial in material terms and in terms of time.
Rules for the care of corrugated pipes
Smooth-walled corrugations can be easily and easily cleaned of dirt. The sectional structure is easy to maintain, and products with a corrugation diameter of 120 millimeters are easy to clean by sticking a hand with a sponge inside. Sections are easy to remove and install.
When the walls of the corrugation are embossed, it is more difficult to clean the dirt. It is in the folds that dirt, dust and fatty deposits accumulate during the operational period. Because of this, many homeowners do not spend time cleaning and buy a new pipe.
Having familiarized yourself with the installation features and the rules for choosing corrugations, 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. Accurately and efficiently installed corrugated pipe willserve many years.
