Belzona Facts:

A Belzona® SuperWrap repair, compliant to ISO/TS 24817 and ASME PCC-2 Article 4.1, was applied to provide reinforced protection to the weak and vulnerable areas of the corroded pipework. Using a Belzona® SuperWrap repair, the client was able to eliminate the need for hot work and this approach also minimized the time the pipe system was out of service. The pipe repair was completed within two hours and was back to full strength following a forty-eight-hour cure period.
