Copper pipes are not able to interact with various household liquids such as: oils, fats, detergents, etc. It is worth noting that chlorine, which is contained in water, does not destroy the inner surface of the pipe, but, on the contrary, protects it from damage .
In similarity with plastic pipes, copper is attractive in that it is impossible to form build-ups inside the pipe, which contribute to clogging of pipes. According to the descriptions in GOST, pipes can withstand fairly high temperatures and sudden changes are not a reason for them to break.
This type of pipe with a size of 14 inches in diameter is very flexible. In accordance with this, the pipes become safer because they do not collapse during the cooling of the water.
The main difference from other types of pipes is that the impact of various chemicals and paints is not a reason for destruction, but on the contrary, it is protection for a copper pipe and an attractive design. In addition, there are pipes on sale that are pre-treated with chrome for further painting.
Copper pipes are capable of melting at a temperature of 108 degrees.
Copper Alloy Pipe Types
In household devices, they are divided into:

     Annealable (annealed copper pipes);
     Incapable of annealing (unannealed).

In the first form, the pipe has the ability to be fired, which contributes to the softness of the pipe. But the stability and strength of the pipe at this time, apparently changes for the worse. This type is mounted by several dozen pipe sections of approximately 2.5 meters in size. In the second type, the finish is made in the form of straight-type segments approximately 5 meters in size.
unannealed copper pipes
The type of section can also differ from each other, and you can find a pipe with a rectangular section on the market. This type is usually used in stator-wound electrical machines that are cooled with a special fluid. It is worth noting that the production of this type is quite complicated and therefore the cost will be more expensive.
The main features of copper pipe finishing
To get started, measure and cut the pipes into pieces. The cross section of the pipe must be even and for this you need a special pipe cutter.
Technology for attaching pipes to each other
Copper pipes do not need to be threaded.
You can connect them to each other in two ways:

         With the help of soldering;
         By pressing. (see Hand press for pipe)

Most often, the connection is made by soldering. Since this method creates the strength and tightness of the pipe.
Production
For the production of pipe fittings, copper alloys are used, the copper content of which is determined by Russian GOST 617-2006 (instead of GOST 617-90), R 52318-2005, 859-2001, 11383-75 and the European quality standard EN 1057, and, as a rule, never less than 99.5%. There are the following grades of copper:

     M1. The content of copper in combination with silver is 99.9%. Almost absolute purity of the alloy provides the best indicators of ductility, strength, thermal and electrical conductivity of the material. The M1 brand is recommended for heating circuits (max t of the working medium - 250⁰С), as well as cryogenic installations.
     M2. The content of copper and silver is 99.7%.
     M3. - the so-called technical copper, made as a result of secondary remelting or fire and electrolytic refining. The content of copper and silver is 99.5%. Rolled metal grade M3 is characterized by good strength and affordable cost.

A decrease in the proportion of copper and an increase in the proportion of alloyed elements (nickel, tin, iron, lead, arsenic, etc.) primarily affect the electrical conductivity coefficient, significantly reducing it. At the same time, the strength index remains practically unchanged.
Advantages and disadvantages of copper pipes
The physical characteristics of copper in symbiosis with production methods predetermine the operational features of copper pipe, which is resistant to:

     Corrosion, which not only prolongs the life of the pipeline, but also does not adversely affect the operation of plumbing fixtures.
     Temperature differences while maintaining the integrity of the linear parameters.
     Water hammer. The working pressure of the circuit is from 100 to 450 atmospheres.
     Vibrations, due to which copper pipelines are actively used in seismically unstable regions, including for arranging gas distribution.
     UV rays (unlike thermoplastic polymers, which are destroyed by ultraviolet radiation). The coloring of the copper pipeline is carried out solely for the purpose of adapting it to a specific interior.
Also, the advantages of copper pipes include:

     Wide operating temperature range - from -200⁰С to 350⁰С (depending on the pipe manufacturing method and the type of pipeline connection).
     Absolutely smooth surface that prevents the formation of build-ups of organic and inorganic origin inside the contour, without reducing the propperformance while minimizing friction within the circuit, allowing smaller diameter pipes to be used without compromising system performance.
     Plasticity - a guarantee of resistance to tearing. The coefficient of relative elongation (expansion) is 10-40%.
     Plasticity also facilitates installation work. Pipes can be easily bent in any direction using conventional hand tools, which is an indisputable advantage when creating complex contour lines.
     With all its softness, copper fittings perfectly hold a given configuration, which most plastic pipes cannot boast of.
     Lighter weight compared to steel and cast iron counterparts facilitates transportation, installation and minimizes the load on the building.
     Chemical neutrality to salts, formaldehydes, methanol, a number of acids with a pH level of not more than 9 prevents the destruction of copper. The lack of reaction with chlorine contained in tap water does not provoke the formation of oxides harmful to humans.
     The bactericidal properties of copper contribute to the partial disinfection of water. In copper pipelines, not only do microorganisms not multiply, but the bacteria of Staphylococcus aureus and the group A influenza virus also die.
     The low electrostatic index prevents the formation of sparks, which means that copper fittings can be safely used in the field of flammable and explosive industries.
Kinds
According to the wall thickness, copper pipe is divided into thin-walled and thick-walled. The first one is lightweight, the second one is more durable.
In addition to standard copper pipelines, plastic-insulated pipes are produced, which:

     Cools the surface of the pipe.
     Prevents condensation.
     Keeps heat inside the circuit.
     Reduces noise level.

Depending on the type of final treatment, rolled pipes are divided into annealed and non-annealed. Visually, they are easy to distinguish from each other: annealed, as a rule, are supplied in coils up to 50 meters long, unannealed - in straight segments.
Marking
Marking of the outer, inner diameter and wall thickness of the product is carried out both in mm and in English inches. It's easy to translate one into the other. For 1 inch take a diameter of 25.4 mm. However, in practice, this is rounded up to the usual 25 mm. It is also customary to round other sizes in mm relative to an inch.
Accordingly, common definitions in the colloquial speech of specialists sound like this:

     a diameter of 50 mm is called a two-inch;
     pipe 15 mm - half an inch;
     32 mm - per inch and a quarter;
     20 mm - three quarters of an inch.
