Rapid solution

Due to health and safety concerns hot work was not an option. The client needed a fast solution with minimal service disruption as every day of shutdown was costing £1.5m.

The application team was able to work on live equipment, so production could continue. Where leaks were present, a plate was bonded using a fast curing repair compound Belzona 1221 (Super E-Metal) over a holed area. A temporary wrap was created over that area using the same material. Then, the whole pipe was wrapped using Belzona 4301 (Magma CR1 Hi-Build), a material known for its chemical resistance properties. Belzona 1831 (Super UW-Metal) wrap was finally applied on top and also used to encapsulate the adjacent flange.

Should the metal underneath the Belzona wrap continue to deteriorate and a through-wall defect occur, Belzona 4301 (Magma CR1 Hi-Build) would resist the contents of the pipe. Belzona 1831 (Super UW-Metal) in turn adds mechanical strength, while at the same time protecting the pipework from external corrosion damage.
