Belzona® Repairs Cooling Water Pipe

 
 

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-Barier

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 ST-Barier coating system, which is designed to protect both metallic and non-metal surfaces, which can be applied to wet or wet surfaces that can not be properly dried before application. Subsequently, the areas were pressed with BELZONA® 1111 Super Metal and reinforced with reinforcing sheets. At the end, the entire pipe casing was treated with a two-component coating system for long-term protection of the BELZONA® 5811 Immersion Grade metallic and non-metallic surfaces in combination with the BELZONA® 9341 Reinforcement Tape reinforcing reinforcement fabric.

 
 

Belzona Facts:

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