Applications

    • Compliant or conventional Belzona SuperWrap II pipe wrap system for the repair of complex geometries of pipes including bends, straights and tees

    • Compliant or conventional, wet-applied Belzona SuperWrap II Patch for composite patch repairs of large diameter pipes (over 600mm) and tank walls

    • Conventional, prefabricated and pre-cured composite plate manufactured from Belzona SuperWrap II for plate bonding applications

    • Conventional, prefabricated and pre-cured composite wear pad designed using Belzona SuperWrap II for pipe support – this can be overcoated with an erosion-resistant coating, for example, Belzona 1331, for additional protection and can be formed on site, resulting in minimum lead time
