Customer Location:

Steel Plant, Teesside, UK

2011

 
 

Application Situation:

Basic Oxygen Steelmaking (BOS) Demin water plant. Two bunds for regeneration chemicals - 96% sulphuric acid and 46% Sodium hydroxide.

 
 

Problem:

Belzona® 4311 (Magma CR1)

Belzona Facts:

The client chose Belzona due to the performance the materials offered and its ability to be applied to complex geometry as there were many fittings and platforms in the area.  The client was delighted with the short time taken to complete the work and the final finish.
