Water - ÖEV

In modern households hot water is self-evident. As steel is the standard raw material for boilers there is a question of corrosion resistance.

 

If porcelain enamel is melted onto the steel at about 830-850°C it is more than a coating. During the enamelling process  a chemical and physical compound between steel and the glass-like enamel. The boiler gets its strength from the steel and the necessary corrosion resistance from the glass coating. The melted-on layer avoids any rusting. Porcelain enamel acts like an insulation because there is no absorption of water or electric conduction.

The glass lined steel is temperature resistant from -60°C to +450°C and extreme temperature changes are also no problem.

Special enamels were developed. These provide an optimal adhesion to the steel and fulfill every requirement for boilers. They show a very high resistance against water, steam and acids and they are physiologically harmless.

The enamel layer itself would provide a corrosion protection of 99% but to reach 100% anodes are installed.

  

Enamel provides highest protection for over- and underground hydrants, pipe systems, valves and connection parts because it is resistant to acid soils, frost, heat, wind and snow.
