Stainless steel water hoses

Resistance to corrosion is one of the most important properties of water hoses, for ensuring the long life of the component.

Hoses are widely used, especially in the plumbing, building and construction sectors. In these sectors, it is important that water hoses withstand working conditions which are certainly not comparable to domestic conditions: for example, the operating pressure required to push water along a height of several metres must not impair the structure of the hole itself.
For this reason, stainless steel hoses are preferred over plastic hoses for these kinds of uses, even though plastic obviously ensures good sealing in terms of thermal insulation.
As well known, resistance to corrosion is an essential property where metal works in close contact with corrosive agents such as water and oxygen: in the presence of these two agents the metal tends to release electrons that bond with the hydrogen ions present in the water. Subsequently, hydroxide is formed that, combining with the metal ions, creates what everyone knows as Rust. This is the most classic cause of corrosion. In order to avoid rust forming, you generally have to resort to using metals with percentages of chrome and nickel (but especially chrome), in order to allow the formation of a protective layer that insulates the underlying metal from atmospheric attacks: this phenomenon, which is integral to the water hoses designed by Gnali Bocia, is called passivation.
