Stainless steel hoses for domestic use

From residential use to heating and boiler systems: stainless steel hoses are an effective solution for many structures.

In domestic environments, boilers and heating systems, many of you will have surely noticed the presence of metal hoses covered in a protective casing made of rubber or rigid plastic. These hoses are made of stainless steel, a metal alloy made up of Iron, Carbon, Chrome and traces of Nickel. It is the Chrome and Nickel which provide steel and the hoses with anti-oxidation properties, a fundamental requirement for the containment of gas or liquid flows which could have a corrosive effect on the internal walls of the hoses. Another external protection is provided by the casing which guarantees an adequate protection against the elements which could cause external damage to the hoses.  Despite the apparent simplicity of their construction, these stainless steel hoses must meet the conformity requirements which guarantee the reliability of the product when subjected to mechanical strain, even if much greater than those pertaining to normal use.
Similarly, the outer covering of the hose is subjected to a series of controls in order to avoid any losses or faults on the surfaces of the hose.
The specific standard for stainless steel hoses is UNI-CIG 9891: the UNI acronym indicate that the standard is accredited by an Italian organisation while CIG identifies the subcategory of the component which is fluids in a gaseous state; finally the series of numbers correspond to the exact reference standard for the hoses subjected to certification.
