Customer Location:

Zinc Producer, North Carolina, USA

Application Date:

July 2015

Application Situation:

400,000 sulfuric acid holding tank nozzle.

Products:

Belzona 4311 (Magma CR1)

Substrate:

Carbon steel

Application Method:

The tank nozzle flange and inside neck area was blasted to prepare its surface for the Belzona coating. Belzona 4301 was used to build the tank nozzle flange back up to its original shape. Two coats of Belzona 4311 were used to coat the flange and the interior of the tank nozzle.
