Aluminum tube is a modern and practical solution for many

The time has passed when only iron products were used for laying the line. Today corrugated aluminum tube enjoys wide popularity due to its excellent qualities. We will tell you about this and other varieties further.

Key properties

Aluminum pipes are controlled according to GOST 18475 82, therefore it is possible to speak with confidence about their quality. Next we look at the main features that they own.

Merits

First of all, our instructions will affect the main positive qualities with which the products described by us are endowed:

• Easy molding and processing. Any person can do this or that manipulation with their own hands. To do this, you do not need to have special expensive equipment.

Tip: for the connection, you can use special fittings for aluminum pipes, which provide high reliability.

• The light weight of the aluminum tube makes it easier to work with.. It also affects transportation.

• Resistance to corrosion and other aggressive media. In this aspect, they win over most of their fellows.
• The widest range of aluminum pipes allows you to solve any, even the most complex tasks.. They can be of various shapes and sizes, which greatly simplifies the life of highway makers.
• It should also be noted, and the smallest roughness. This property contributes to increased throughput. Therefore, it is comfortable to transport various liquids into them.

It is interesting: the carrying capacity of aluminum is 30-40% higher than that of steel and copper.

• Affordable price. Today this is a very important property, because many of us make our choice based on the financial component.

Among all these, of course, important advantages, there was one drawback. Relatively recently, the carcinogenic properties of aluminum have been discovered. Therefore, it is not recommended for drinking water.

Classifications

Aluminum pipe according to GOST can have various classifications. Let's look at them all:

In form, it can be:

• Rectangular.
• Oval.
• Round.
• Square.

The thickness of the walls is:

• Thick wall - over 5 mm.
• Thin-walled - from 1 to 5 mm.

In addition, all samples are divided by the class of quality characteristics. This indicator is the most important among others.

So, there are four classes:

• B - characterized by the normalization of the chemical composition.
• B - rationing of mechanical qualities.
• E - not subject to heat treatment. Most often, these are samples with a diameter of less than 22 mm, because, as a rule, they do not require increased technical characteristics.
• D - are not subject to rationing, and both chemical and mechanical. However, such products are subject to pressure regulation.

There is also a division into groups regarding the method of production:

• By cold deformation, the aluminum circle acts as the raw material. It is consistently pulled, stitched and calibrated. This technology is used, including for specialized products, for example, samples of size 10x2.
• Pressed.

• Made by welding. Sheets or strips are used as raw materials. After welding, the pipe is subjected to tempering, which provides stress relief at the seams.

Scope of application

As we have already said, the material described by us has received the widest distribution in many spheres of our life.

Therefore, it will not be superfluous to call them all:

• Ventilation shafts.
• Boxes for various communications. Here the advantage in weight plays a very significant role.
• The creation of metal structures of various sizes.
• Furniture production (as decorative elements).

Note! For additional protection against aggressive media, anodizing is often carried out.

• Transportation of liquid, bulk and even gaseous substances.
• Extractive industry.
• In the field of construction - where you need to create the most lightweight, and at the same time strong frame. So from pipes with a diameter of 25 mm, you can create a resistant design that will cope with serious loads.
• Arrangement of pools.
• In private construction. As we have said, for the organization of drinking water such material is not suitable. Therefore, it is used mainly for ventilation lines.

A few words about the alloys

Excessive plasticity of aluminum does not always carry positive aspects. Quite often it is required that the finished product be rigid, for example, for pipes with a diameter of 50 mm or more, used under conditions of strong mechanical loads. In this connection, various alloys began to appear, acquiring some additional properties.

At the beginning of the last century duralumin (an alloy with copper) was created. It has been found that the addition of copper contributes to an increase in rigidity and strength. Such a property could not go unnoticed.

Today, manganese and magnesium are added to such alloys, producing various grades, the most famous of which is D16T. In addition, now all products are subjected to special heat treatment, designed to improve the most important characteristics.

In conclusion

Now you know, for example, how the aluminum tube D16T differs from its counterparts. However, if you could not understand all the subtleties, then do not worry. In the presented video in this article you will find additional information on this topic, which will allow you to comprehend all the nuances.
