Belzona Facts
A doubler assembly was manufactured from a curved plate and oversize pipe. This was then cut to allow easy assembly. The plate was then sealed and injected with Belzona® 1391 to act as an adhesive. Once completed the whole assembly was protected from further corrosion by application of Belzona® 5111 and Belzona® 6111. Application reported OK in February 2008 and many other similar applications carried out for the client.
