A six inch diameter pipe, carrying water and condensate, operating at 30-50°C and 31 Bar pressure.
A Belzona® SuperWrap reinforced repair, compliant to ISO/TS24817 and ASME PCC-2 Article 4 was designed and applied by validated applicators.
Large parts of the system were planned to be removed by the end of 2011 due to these defects. Using Belzona® SuperWrap, the client was able to significantly extend the lifetime of the system without the need for hot work. The repair was completed within twelve hours and after a 48 hours cure period the system was back in service. The Belzona® Superwrap was designed so that integrity in the system was maintained even after the defect goes through-wall. The Belzona® SuperWrap repair is compliant untill 2016.
