Water / Salt water

The presence of water in the work environment is practically a constant: in the form of vapor it constitutes the humid component of the air, but it can be present in liquid form in many work cycles (with cleaning or cooling functions) or even in form of snow or ice in open environments subjected to severe winters. Water has corrosive properties towards some metals and alloys, in particular steels and cast irons; the presence of ions or dissolved salts can greatly increase these processes and require physical and chemical protection interventions. In liquid form, water can be under pressure, creating further problems on the resistance of the seals and increasing the possibility of coming into contact with apparently protected metal parts.
