Отрасли промышленности:

General Industry (GIND)



Tanks and Chemical Containment Areas (TCC)


Местоположение клиента:

Cement manufaturer - Tunisia


Дата применения:

February 2004


Ситуация применения:

Electro-static precipitators



The Electrostatic precipitators at this large cement manufacturer operate at 70kv and 200°C (392°F). As a consequence they are insulated to conserve heat energy. As usual the insulation is protected by the use of jointed steelsheeting which does not prevent moisture from penetrating the insulation layer. The result is under insulation corrosion made worse by the fact that the site is coastal and the atmosphere is salt-laden.

Факты Belzona (Экономия средств? Альтернативы? Почему Belzona?, и т.д.):
