Rapp-it Pipe Repair Bandage is suitable for use on dilute acid lines. Many mining facilities use acid contents to aid the stripping of minerals. Rapp-it has been tested against several different acids and has superior chemical resistance.
SCOPE
The customer advised they had a leak in the acid column outlet bend to the extraction column as part of the stripping circuit in gold production. The bend had previously been repaired with a steel patch, but a leak occurred just above the repair weld.
SOLUTION
The customer reduced the line pressure and then cleaned and roughened the area. The leak was stemmed with Rapp-it Steel Putty and a Rapp-it Pipe Repair Bandage (100mm x 3.6m) applied over the top. The line was up and running at full capacity, 30 minutes after application.
