Aluminum pipe production
Advantages
It has a very high plasticity, thermal conductivity, and special resistance to various types of moisture: atmospheric and soil. In addition, aluminum pipes remain resistant to unfavorable environmental conditions even with large temperature fluctuations. Aluminum itself can be easily processed and deformed, because it is very plastic. Accordingly, aluminum pipes can easily be cut and bent. Aluminum is one of the most hygienic metals. The outer and inner surfaces of the aluminum pipes are very smooth. This smoothness justifies the high capacity of the pipes, which is why they are constantly used in communication systems.
Pipes of minimum diameter are suitable even for the most complex systems. If we compare aluminum pipes with other metals, then the pluses should be attributed to the fact that they are mainly used for very plastic alloys. Due to this, aluminum pipes have good weldability and high processability. It is because of the numerous advantages of such pipes that aluminum rolling has a great demand in modern industry.
Marking
The strength characteristics of aluminum are greatly increased by heat treatment. The pipe aged artificially and hardened has the marking АД31Т1, in case it was not subjected to thermal treatment — АД3. If the pipe is not fully artificially built and is hardened, it will be designated AD31T5.

Aluminum pipes are thick-walled and thin-walled with a matte surface. Delivery of pipes is carried out in lengths of unlimited length or bays. The metal rolling is free of impurities and has no defects, its surface is cut smoothly, without burrs. Transportation, packaging, storage, temporary anti-corrosion protection is carried out in accordance with GOST 9 .510−93.

Aluminum pipes are produced with quenching by the method of artificial or natural aging using a hard and annealed material. First, hardening takes place, after which the material can be further strengthened by means of a curing technique. After that, the aging process: natural or artificial.

Using
At the moment, aluminum pipes have become simply irreplaceable elements in such areas as the production of building and electrical structures, the design of cars, ships, airships, aircraft, in finishing works, as well as in the fuel, chemical and food industries. They are included as components in engineering systems for household and cryogenic equipment. Aluminum pipes are used for installation of heating systems, drainage networks, main pipelines, gas pipelines, water pipes, air ducts, heating systems. They are ideal for manufacturing radiators, gasoline tanks and pipelines used for fuel and lubricants.
Duralumin pipes
The most demanded of aluminum alloys is duralumin. It consists of aluminum alloyed with manganese, copper and magnesium. If you compare duralumin and aluminum pipes with steel, they are much cheaper, lighter and longer serve. In addition, duralumin withstands fatigue loads with ease. This material can be strengthened by additional heat treatment, such as hardening, artificial or natural aging. But duralumin has one drawback, it is prone to corrosion and, therefore, it is necessary to apply an additional film of pure aluminum to its products.
Application
Duralumin pipes in transport engineering for the design of aircraft, ships, cars, radio and electrical equipment today have become irreplaceable. Of these, lightweight and durable frame structures are produced.
Example of marking: Duralumin pipe GOST 18482−79 D16T 60.10 means that the pipe made of alloy D16T, of round section and conforms to GOST 18482−79, was not subjected to heat treatment, the wall thickness is 10 mm, the outside diameter is 60 mm, the length is non-dimensional.
