Complete repair after consolidating with the release film to be later removed

Application Situation

The pipe was so deteriorated that they were concerned that abrasive blasting the bottom of the pipe will puncture the pipe and create through wall defects. It was decided to do a plate bonding with a surface tolerant product as an initial reinforcement before further reinforcing with SWII.

Application Method

First, the pipe was prepared as best as possible. The we did a plate bonding repair with Belzona 1161 to protect the bottom section of the pipe. After, we grit blasted the rest of the pipe and reinforced the rest of the pipe with Belzona Superwrap II.

Belzona Facts
