🔧 Gofra for drawing: variety, dignity, self-assembly

Almost every kitchen in modern apartments and private homes equipped with hood. It is mounted directly above the kitchen stove and may be autonomous with special filters or connected to a common ventilation system using duct - flutes. Today the online magazine HouseChief experts will tell what is a flute for drawing what species exist and how to install it by hand.

Corrugated pipe and the scope of its application

Corrugation is a hose or tube, the ability to stretch, shrink and turn in any direction without prejudice to the inner diameter. It consists of a frame, usually made of wire, and a sheath of PVC, steel or aluminum foils and other materials. It is used for devices of different engineering systems: water, heating, gas communication, warm floor, ventilation etc. In household corrugated pipe is mainly used for kitchen hood with a compound obschedomovoy ventilation system. Largely due to the ripple from the kitchen there are various smells and vapors that are formed during the cooking process.

Pros and cons of corrugated pipe for exhaust

Before you buy a corrugated pipe for exhaust, should be familiar with its advantages over other types of air ducts, as well as learn some drawbacks.

Among the advantages of corrugated pipe is worth noting the following:

However, despite such a number of advantages, in corrugated duct for hood has its drawbacks, though few.

The main parameters of a corrugated pipe for ventilation, which is necessary to pay attention

Going choose corrugated ducts for ventilation, it is necessary to consider two major parameters: the diameter and length. The first component is determined by the outlet on the extractAnd for outputting a obschedomovyh ventilation pipe can use a special grating with an adapter. A wrong duct increase the burden on the hood, will reduce the efficiency and increase the noise level. Manufacturers offer four major corrugations size for drawing with a diameter - 100, 120, 125 and 150 mm. There corrugated pipes and other diameters, but the most common - 100 and 120 mm.

As for the length of the corrugated pipe for ventilation, it is mainly produced air ducts 1 and 3 meters. To select suitable corrugation, it is necessary to measure the distance between the hood ventilation considering all angles and planned turns. To obtain the value necessary to add 10-15% of the required length and out of the tube.

Varieties of corrugated material for the extraction of

Current manufacturers offer corrugated tube for ventilation of the most different materials: aluminum, steel, PVC, etc. Each of them has its own advantages and disadvantages. Let us consider them in more detail.

Steel and aluminum corrugated pipe

Aluminum corrugated duct is the most common type of air duct, which can be used in the system ventilation. In such a product a lot of advantages:

Pipes of the steel strip, unlike corrugations of aluminum for ventilation can withstand fairly strong air flow and high temperature. However, they have considerable weight and more complex installation.

The disadvantage of steel and aluminum corrugated ducting is that if a fan of high power, there is a lot of noise and vibration increased. Also corrugated aluminum susceptible to mechanical damage, so use them very carefully.

Plastic corrugated ventilation

Very often, the compounds for kitchen hood with ventilation obschedomovoy use corrugated pipes spirally-wound type of PVC. This is due to the fact that such corrugations are characterized by:

However, before you buy a plastic corrugated for drawing, you should know about its shortcomings, namely: fire hazard, toxic emissions during combustion, low strength, poor tolerability low temperatures.

Other types

There are other varieties of corrugated pipe for ventilation, which are used less frequently due to objective reasons. Thus, for example, corrugated, thermally insulated duct is used to protect a high operating temperature. Typically such constructions are mounted on the outside of the building, which can significantly reduce the formation of condensate inside the pipe.

Pipe with a polyester film is a metal wire frame, wrapped in several layers of film. Light construction is obtained and can be used to work with low pressure and temperatures. The disadvantage is that the corrugated thin Membrane wall is easily damaged, so it is best used for flush mounting

Selecting the corrugated pipe: expert advice

A man who had never before encountered with the installation of the hood and the duct, it will be difficult to choose a suitable corrugated. Therefore, our editorial experts decided to gather some practical tips on what to consider when buying corrugations. By purchasing a flexible duct, should be guided by the following main characteristics:

• diameter and a length;
• material;
• appearance;
• price.

The diameter of the flexible duct is usually specified by the manufacturer or that the equipment in the instructions. For institutions corrugations in the duct, as a rule, require special ventilation grille. In any case, it is necessary to measure the exhaust outlet and in accordance with it to select the diameter of the corrugated pipe.

corrugation length is 1-3 meters, so Gaugeable predetermined distance from the grille to the hood ventilation installation place in view of bends and corners. Do not take the pipe with a large reserve and pay at the same time. Corrugation must be stretched in order not to degrade system performance.

The material of construction of the corrugated pipe, it is very important, particularly if the duct is mounted on the extractor hood. Commonly used corrugated steel or aluminum strip. Plastic design is best used in the ventilation to the circulation of cold air, because the material is easily heated and loses its quality.

When buying corrugations need to carefully inspect it for physical damage: dents, cracks, abrasions, and other defects. It is also recommended to ask the seller a certificate of quality and certificate for the product, which must be specified warranty period of not less than 12 months.

Price. Before heading for the purchase of corrugated pipe for exhaust is desirable promonitorit prices in your city, depending on the manufacturer and the seller. This will help you significantly save and choose the product with the best value for money.

How to Install a corrugation on the hood in the kitchen

Run the installation of the corrugated pipe, anyone can for kitchen hood. This requires a minimum set of tools and a little time. In some cases, the installation takes longer than 1 hour. Below, we consider that it is necessary to set the corrugations, and describe in detail the process of its installation.

To create a duct between the kitchen hood and obschedomovoy ventilation system you will need:

• Corrugated tube with a diameter corresponding to the size of the pipes and on the exhaust ventilation grid;
• two clamp (metal or plastics);
• ventreshotka with a nozzle;
• adapter;
• Novoselov with self-tapping screws;
• sealant and an aluminum tape (if required);
• crosshead screwdriver;
• pliers;
• wallpaper scissors or a knife.

Step by step instructions for installing the corrugations on the hood

As you will see from the steps below to install corrugation on the hood and connect it to the ventilation system of the forces of any person. To do this, you need to have the minimum skills working with a screwdriver.

Illustration	Description of the action
	Purchases and extract corrugation suitable diameter and length
	The wall cabinet, which is attached to hood, need to partition a jigsaw and cut hole for corrugated pipe
	In our case, you will need an adapter to extract the socket corrugation. It can be purchased at almost any store climate, household appliances or building market
	Set the adapter to the hood. For the connection reliability can be treated with a sealant
	At the end of the tube worm put on the yoke, and to sit down on her plastic adapter
	With a screwdriver tighten the clamp. The main thing is not to overdo it
	We vent bred in plasterboard box. We took the tube with a check valve, although most of them are already equipped with hoods
	Gently derive the pipe through the opening in the hood
	Also, gently straighten corrugation, being careful not to bruise her
	We put on the pipe clamp, and attach it to the air conduit with a check valve. Tighten the clamp with a screwdriver. In this setup can be considered completed

How to connect with each other corrugation

As mentioned above, the standard length of corrugated pipe for ventilation is 1-3 m. Usually, this is enough, but what if the distance between the hood and the ventilation duct is greater than 3 m. In this case need two tubes which are interconnected by means of a special plastic couplings and clamps. If the hand is not turned an appropriate pipe diameter, the corrugations may be joined together by an aluminum tape.

How to hide the corrugation of the hood in the kitchen

Whatever kind of corrugations for drawing you choose, to be honest, it will not have the high aesthetic characteristics. L

uchshim embodiment will mask the duct, keeping in mind that it should always to be easily accessible for maintenance or replacement. Consider the most common methods.

1. Corrugated box can be hidden in a plasterboard (or separate within the tiered ceiling structure).
2. Corrugation hiding behind the plastic boxes that can be purchased in DIY stores as a decorative element. These boxes are available in a variety of forms, colors and even equipped with lights. However, this option is suitable if the hood is located near ventkanala.
3. Air duct can be hidden in the wall cabinet, which is attached to the hood.
4. Corrugated pipes can decorate, making it part of the interior, or simply paint to match the walls.
5. Hide duct for the wide eaves of kitchen units.

Care corrugated duct and should be replaced

Corrugated pipe - a fairly inexpensive option duct from the cooker hood to the ventilation duct. If done correctly, its operation will be a long and trouble-free. However ripple over time accumulate dust and grease. Tube must be periodically cleaned with a soft cloth and soap solution. Particular attention should be paid to places between the folds.

Although the term corrugated pipe service is up to 10 years, it accumulates in the fat, soot and grime that can prevent the air move. This contamination is almost impossible to remove. The best option would be to purchase and install the new corrugation, the more that it will cost inexpensive. After dismantling of the old pipe the new set in the same way as described in the steps below.

Comparison of flexible corrugated ventilation duct with a rigid

Many prefer to use as a duct between the hood and vent plastic round pipe or conduit of rectangular section. Such a solution has its advantages and disadvantages. The advantages of plastic ducts to flexible corrugated pipes include:

With the advantages of plastic ducts, we figured out, and now look at what they lose corrugated pipe for exhaust. Among the shortcomings:

corrugations cost hoods and accessories

The minimum set for installation on corrugated hood is inexpensive and affordable for everyone. It was the reasonable price largely determines the choice in favor of a corrugated pipe.
