Carbon Steel

 
 

Application Method:

Application was carried out in accordance with Belzona Know-How Leaflets TCC-3 & TCC-5. Belzona® 1311 was used to repair pitting and to smooth out weld repairs before the lower part of the vessel was coated with Belzona® 1391.

 
 

Belzona Facts:

Previously the eroded/corroded areas had been repaired by the customer's own staff  welding and grinding those areas almost each year during seasonal shutdowns for maintenance. This sort of conventional repair presented a safety risk and was time consuming. The decision to use cost-effective Belzona protective system saved company money, time and reduced risk. In addition Belzona coating will provide long term resistance to the chemical attack and corrosion.
