Application Method:

Application was carried out using a modified version of Belzona System Leaflet SHM-11. Application area was roughened using a grinder and grooved using a die grinder.  Rebate grooves were cut in at the edge of the application area.  Final cleaning was done using Belzona 9111. The edges were taped in order to keep the Belzona material within the prepared area. Belzona 1812 was then applied, taking care to push it well into the roughened area before building it up too thickly. Final thickness was approximately 1/4 inch.  

 
 

Belzona Facts:

The OEM equimpent was not lasting for more than a few weeks in the environment the constant blowouts were creating unscheduled shut downs and lost productivity.  The Belzona application has been in place for 6 months and is still performing well with no blowouts.  The customer is now also adding Belzona 1812 to their pipe bends where they had previously had to use customer made bends with a high wear resistant steel.
