Refinery Slop Tank Protected With Belzona

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Oklahoma, USA

 
 

Application Date:

March 2005

 
 

Application Situation:

Base of a storage tank containing crude oil and some medium molecular weight hydrocarbons.

 
 

Problem:

The bottom internal section of the tank was leaking from a previous coating failure which lasted less than two years. The refinery was looking for a longer term solution to protect the tank bottom from corrosion. There was not enough time to replace the bottom.

 
 

Products:

Belzona 1121 (Super XL-Metal)

Belzona 5811 (Immersion Grade)

 

Substrate:

Carbon Steel

 
 

Application Method:

New steel plates were welded over the existing through wall defects. The welds and pits were filled with Belzona 1121. Two coats of Belzona 5811 were applied afterwards in two contrasting colors.

 
 

Belzona Facts:

Belzona lasted over seven years compared to the previous coating, saving from the labor cost and taking the tank out of service three times.
