Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Irrigation District - Wyoming, USA

 
 

Application Date:

March 2007

 
 

Application Situation:

Galvanized steel pipe used to carry 400 ft³/s of irrigation water.

 
 

Problem:

Debris, sand, and silt carried by irrigation water wore through the galvanizing in one season. Left uncorrected, the underlying carbon steel pipe would quickly corrode leading to soil erosion.

Belzona® 5811 (Immersion Grade)
Belzona® 9331 (Reinforcing sheet)
 

Substrate:

Galvanized steel

 
 

Application Method:

Belzona® 5811 and Belzona® 9331 were applied in accordance with a modified Belzona Know-How System Leaflet VPF-2.

 
 

Belzona Facts:

Replacement of the damaged pipe would have cost $700,000 and taken considerable time to complete. The Belzona repair was conducted quickly in situ and saved the customer $650,000. Inspected after one season and found to be in excellent condition.
