Belzona® Repairs Cooling Water Pipe At A Steel Plant

 
 

Industry:

Fluid Flow (FLOW)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Czech Republic

 
 

Application Date:

May 2012

 
 

Application Situation:

Steel plant cooling water pipe.

 
 

Problem:

Corrosion had caused heavy damage on cooling water pipe, therefore weakening the jacket. This may have eventually led to a through-wall defect which would cause a costly downtime period.

 
 

Products:

Belzona 1111 (Super Metal)

Belzona 5831 (ST-Barrier)

Belzona 5811 (Immersion Grade)

Belzona 9341 (Reinforcement Tape)

Belzona 9111 (Cleaner/Degreaser)

 

Substrate:

Steel

 
 

Application Method:

After removing the impurities, the pipeline was treated with the Belzona 5831 coating system. Subsequently, the areas were pressed with Belzona 1111 and reinforced with reinforcing sheets. At the end, the entire pipe casing was treated with a two-component coating system for a long-term protection of Belzona 5811 in combination with Belzona 9341 reinforcement tape. 

 
 

Belzona Facts:

The reinforcement could be carried out whilst the pipe was offline, thereby avoiding costly downtime.
