Copper pipe
Relevance
Copper was one of the first metal, mastered by people, along with tin, iron, silver and gold. In some production areas it is no alternative material, for example, in electrical engineering. Although it is inferior in strength steel alloys, but surpasses them in adaptability and corrosion resistance. Copper pipe not only shows excellent corrosion resistance and high ductility and thermal conductivity. Seamless copper pipe of circular cross section is widely used in heating systems of several European countries, water and gas. It is hardly replaceable in the air conditioning and refrigeration circuits. It is easy to assemble, available in any kinds of processing. It is easily cut, drilled, easily soldered hard and soft solders, is remarkable for its resistance to action of aggressive reagents, durability.

Dignity
Copper pipe and fittings — lighter than steel, easier to install, more resistant to all types of corrosion, including atmospheric and soil. They are plastic, durable, easily welded and soldered, capable of withstanding substantial differential pressures and temperatures comply with the most stringent sanitary standards. On their inner surface does not breed bacteria or fungi, copper does not react with chlorinated or sea water. Copper pipe is relatively cheap Ease of installation, aesthetic appearance, long service life — make this tube extremely beneficial for use in various industries. It works in the temperature range from +250°C to cryogenic temperatures, in addition, copper is harmless to human and durable.
Disadvantages
Copper plastic, but soft, the strength of copper tubes and relatively low if compared with steel alloys.
Manufacturer
For copper pipes use technically pure copper grades M1, M2, M3. Chemical composition normalized GOST 859−2001. The surface should be brushed clean without any defects, signs of contamination, possible traces of broach. Precision fabrication can be increased or normal in diameter and wall thickness. Control of the chemical composition of the normalized GOST 24 231−80. Water thick-walled copper tubes are manufactured according to GOST: 617−90, pipe rectangular and square — GOST 16 774−78, capillary tubes — GOST 2624−77, pipe waveguide — GOST 20 900−75, tube thin — GOST 11 383−75, pipes of copper-Nickel alloy MNZH5−1 — 17 GOST 217−79; pipes for heating and heat exchangers — GOST 21 646−2003 copper Tube for air conditioning circuits produce according to specifications 184 450−106−181−2006.
Fittings
The connecting fittings are made of copper of the same brand. Installation is either high-temperature capillary soldering (strength of such connections is greater than strength of pipes), or use a press≤fittings, swaged to who press≤tools. The last fittings are installed faster, x I less durable.
Application
Copper pipe fittings significantly reduces the cost of installation. Copper — the most stringent health standards, does not cause allergies, prevents the growth of bacteria or mold. Time of trouble-free operation of such tubes is up to 100 years. They are relevant for climate control systems, refrigerators, create, wind instruments, decorative items. These pipes are demanded in engineering, construction, power engineering. Due to the chemical inertness and safety for health — copper pipe occupies a special place in drinking water. The preference for the construction of the communication of technical and sanitary systems pipes of the same material — significantly reduces costs. Often copper pipe is zag by ion cutting, punching, production of parts rolling in mechanical engineering.
