Today by a science it is established, that 80 % of all illnesses of the person are connected with poor quality of water. Thus if on a waterworks water after clearing has the indicators meeting requests STATE THOSE on potable water in further it is waited by serious tests. Internal surfaces of metal pipelines on which water flows, represent a mix of the rust, the chlorinated carbons, salts of carbonates, heavy metals and bacteria that should affect quality of water. Recently to drinking water water serious claims — and on overwork zhlorirovannosti, and on high concentration of a rust and a scum are presented. With this problem the population consults the methods: someone defends potable water, others use the filters which choice is huge. But there is also other category of people which owing to the ignorance or neglect to the health aggravates a problem, that is not only does not clear water, and transforms it into water dead, dangerous to a life. The article also is devoted this problem. But about all one after another.

Visitors of the building markets are witnesses of unprecedented variety sanitary-engineering zapornoy armatures with marks ITALY, SPAIN. Today the brass spherical crane is zapornaya the armature widely applied in the world. World leaders in production of spherical cranes — Italians.

Same (at first sight) the spherical cranes overflowing counters of specialised markets and shops, at complete external similarity considerably differ at cost: the part from them can be purchased on 35-40 rbl. per item, and other part of "twins" is persistently kept at level 60 rbl. not having received in one shop of a convincing explanation of the reason of availability of serious "rupture" in cost of cranes, we have decided to conduct independent investigation. Not a secret, that at complete external similarity of items a main role in definition of their cost should play structure of the metal going on manufacturing of an item.

On the field performances spherical cranes differ reliability and durability. However at operation after installation the firm item sometimes starts to flow, and at times and at all collapses, causing catastrophic flooding of premises with all consequences following from here. The matter is that now the Russian market is literally flooded by the forged goods. Their nomenclature is so extensive, that it is difficult to name commodity range which the similar phenomenon would not concern. From compact discs, clothes and products to medicines — everywhere it is possible to meet fakes.

But we will return to sanitary-engineering armature. The desire of manufacturers to receive the big profits in the shortest terms pushes them on issue of fakes known European, basically Italian, brands. Thus many holders of the registered popular marks sustain the huge annual losses, measured hundreds millions dollars.

We have purchased all presented kinds of spherical cranes in different shops of Moscow and have carried out the chemical analysis of metal of parts making them. Well-known, that the qualitative brass is the most abrasive resistant, durable and safe material in water systems. The contents of copper, lead, iron in a brass which goes on manufacturing of spherical cranes, is strictly supervised by the European norms. The data obtained as a result of the analysis have allowed us to classify all spherical cranes on quality of alloys of cases and spherical locks on two groups.

I group we conditionally named «Firm guarantees». We have carried the spherical cranes having the case nickelized brass, a sphere the chromeplated brass To this group.

This group included spherical cranes of Italian firms GIACOMINI, STC, RASTELLI and of some others. These firms constantly improve quality of production. For example, till now firm STC made one model of the spherical crane — STC which was base and unique. Result of introduction of new technologies of a steel two subsequent models: STC-IDRO and STC-VALVEX. Quality of a brass of these cranes high, corresponds to the European norms. Cranes STC-IDRO surpass the previous models in the technical indicators. As one of consolidations on a rod instead of rubber new heat-resistant material Viton that has allowed to increase temperature of environment to 1500S, a thickness of a wall of the crane to 2 mm is applied. We will notice, that the thickness of a wall at spherical cranes of firm GIACOMINI — one of leaders of the Italian manufacturers of spherical cranes — also makes 2 mm.

II group has received the conditional name «Any warranties». We have carried the spherical cranes having To this group:
  • The nickelized brass case, sphere chromeplated iron (marks of cranes RR, TK, FM, kvg);
  • The nickelized zinc case, sphere chromeplated iron (marks of cranes kvg, FM).

Quality of a brass at these cranes mismatches the European norms (the iron and lead contents is considerably raised). For definition of a thickness of walls of cranes we had to saw them nozhovkoy. Many spherical cranes had a thickness of a wall less than 1,0 mm, and separate cranes — 0,5-0,6 mm that indicates production evident defects. At such thickness even insignificant efforts to a bend and pressure which arise at installation, especially at opressovke, can lead to crane rupture.

The most vulnerable from the point of view of safety are zinc cranes. Even if the zinc case will not burst because of the raised pressure of water in the Moscow water systems the probability of is great that in a year of contact to the chlorinated Moscow water it simply will be scattered. The matter is that the hyperchlorinated water intensively washes away zinc and, hence, the crane case istonchaetsya. Zinc enters reaction with chlorine in which result the solution of chloride zinc — that "dead" water killing healthy cages of an organism and causing the whole bouquet of oncological diseases is formed.

We wish to pay attention that spherical cranes with identical marks V or FM come across in different performances: the case a brass — a sphere a brass, the case a brass — a sphere iron, the case zinc — a sphere iron. Practically all spherical cranes are declared as Italian production though the devoted people know what of them actually Chinese. Thus, we were convinced, that the false armature has only external similarity to the first copy. The case and sphere material, a thickness of a wall, admissions and other parametres at fakes mismatch the European requests, and installation of such armature is fraught with the big troubles both for health, and for a family budget.

In the conditions of unprecedented domination of the false goods the best means of struggle against them — education. With that end in view we also have begun our story. And in summary accept some practical advice.
  • To define, of what the sphere is made (zapornyiy), it is enough to test crane body its magnet. If the magnet is drawn to the crane case, the sphere iron means, and the crane short-lived and necessarily will make you.
  • Cautiously scratch a metal subject a surface of the case of the crane. If under the nickelized cover light yellow colour the case is made of a brass and if silvery the case zinc appears. To establish the crane with the zinc case categorically it is not recommended, if only you do not carry yourselves to fans of "dead" water in the form of a solution of chloride zinc.
  • The spherical crane with the brass case which thickness of a wall less than 1 mm (to check up a thickness of a wall it is possible only with the help raspila), should be carried to a category of "dangerous". It can burst simply at installation or through rather short time of operation.

We hope, that our advices will need you. Successful purchase!
