Porcelain tube
The most commonly used solution
DESCRIPTION
This type of heaters are manufactured in protective tubes made of firm porcelain. They are delivered with protective caps and connection cables. The main advantage is the possibility of changing the ceramic cartridge (or tubular element) without changing the protective tube. They are used for heating of fluids in electroplating baths and tanks. The heaters are immersed directly in liquid. Porcelain coat is long standing. Due to high content of Al2O3 it is resistant to frequent changes of temperature. Porcelain tubes are not resistant to mechanical damage and shocks. Porcelain tubes can be seriously damaged when operating on dry, outside of fluid. As a rule porcelain tubes are resistant to acids, but hydrofluoric acid is an exception.
APPLICATIONS
- Phosphating baths
- Nickel-plating baths
- Tin-plating baths
- Other electroplating baths and tanks
