Corroded Pipe Repaired With Belzona!



Petrochemical (PETR)



Valves, Pipes and Fittings (VPF)


Customer Location:

Petrochemical Plant, SE Texas, USA


Application Date:

May 2013


Application Situation:

12-inch diameter Natural Gas line that supplies the entire complex of 3 separate plants.



Poor protection on the flange caused corrosion to the pipe and flange. 



Belzona 1111 (Super Metal) for filling pits and gaps between bolts/nuts.

Belzona 5831 (ST Barrier) to prep due to the potential of the pipe sweating.

Belzona 4151 (Magma Quartz Resin) 

Belzona 9371 (Reinforcement) for wrap

Belzona 5111 (Ceramic Cladding) for protection.



Carbon Steel


Application Method:

Application was carried out in accordance with Belzona Know How System Leaflet VPF-11. After proper surface preparation Belzona 5831 with Belzona 9371 reinforcement tape were used in areas where potential pipe sweating could occur due to Belzona 5831's moisture tolerant capabilities. Belzona 1111 was then used to fill in the pits and gaps between bolts/nuts. A final coat of Belzona 5111 was used to protect the flange and pipe from further environmental attack.


Belzona Facts:

The customer needed a solution that would not only stop metal degradation but bring back some structural integrity while providing corrosion protection until 2016 when pipe replacement could be addressed during a site wide outage. Customer decided to use a Belzona solution thanks to a previous repair on a cooling tower pipe completed a previous month.
