KHIA ID: 425
Industry: General Industry (GIND)
Application: TCC-Tanks and Chemical Containment Areas (TCC)
Substrate: Steel
Customer Location: Cement manufaturer - Tunisia
Application Date: February 2004
Products:

Belzona® 3211 (Lagseal)

Problem: 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.
