The Qualities and Advantages of Copper

 

Copper tubes can be used as pipes for carrying water for human consumption in accordance with the provisions laid down in DPR no. 1095 of 3rd August 1968. Their conformance is also extended to the provisions laid down in the European Directive 98/83, on the quality of water for human consumption, and DM 174 of 6th April 2004, which implements the aforesaid Directive, establishing the possibility of using copper tubes as pipes for carrying drinking water and water for human consumption.

Heat technicians, installation engineers and end users can use copper tubes in plumbing installations with maximum tranquillity and safety

 

 

Copper tubes are used on a worldwide scale for carrying drinking water, for heating systems, gas distribution, in hospital medical gas carrying systems, as well as in air-conditioning and refrigeration applications and several types of industrial use.

 

The modern technologies used to work the raw material and subsequently manufacture the finished product, together with strict quality controls, make copper tubes an avant-garde and absolutely reliable product for all applications in which they are used.

 

Copper is a metal with an extremely high electrical and thermal conductivity, second only to silver; it has a high corrosive strength and is not magnetic. It is easy to work, extremely ductile and malleable; it is easy to recycle and has a high scrap recovery rate. Its impermeability, resistance to ultraviolet light, resistance to low temperatures, which enable it to be installed in cold periods without any risk of breakage, constitute a high added value and give the product unique features that are a permanent guarantee of maximum reliability.

 

 

In addition, copper is bacteriostatic, that is, it combats the proliferation of bacteria on its surface.

It has been found that the proliferation of Legionella is reduced when copper tubes are used. The capacity of this metal to inhibit the proliferation of bacteria on its surface was already known in the nautical sector: many anti-fouling varnishes (used to inhibit the growth of seaweed and shellfish) to be applied to the keels of ships contained copper salts; every summer, recommendations are made to insert a copper wire in wells to kill mosquito larvae; in many American hospitals, it is obligatory to make door handles and banisters of brass (a copper-zinc alloy) to avoid the transmission of diseases and pathogenic bacteria. copper is by far the best material against Legionella and other pathogenic bacteria, such as Escherichia Coli, Streptococcus Faecalis and Staphyloccocus Aureus.

In addition, copper ions kill other micro-organisms that Legionella feed on and reduce the growth of the biofilm, which tends to form a protective shield for bacteria.

Its bacteriostatic property, together with other physicochemical and economic characteristics played a major role in the choice of copper alloys in the coinage of the new Euro coin.

 

Due to its high thermal conductivity, it is one of the most effective materials for heat exchanges: this is why it is used in heat exchangers, solar panels, and wall and floor-mounted radiating panels.

The alternative products, made up of several layers of different materials, have no thermal conductivity and have different mechanical/chemical and flow characteristics for each of the layers making them up, unlike copper which has a uniform, low thermal expansion coefficient and uniform mechanical/chemical and flow characteristics.

In addition, copper tubes can be supplied in various physical states (soft, half-hard and hard) and thus adapts better to users’ needs.

Copper is an ecological product, avant-garde for new design concepts due to its extreme adaptability to all manufacturing and installation innovations.
