CASE STUDY

Acid Line Case Study

Rapp-it Pipe Repair Bandage is suitable for use on dilute acid lines. Many mining facilities use acid to aid the stripping of minerals, and Rapp-it has been tested against several different acids with superior chemical resistance.

Scope

The customer had a leak in the acid column outlet bend to the extraction column, 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, 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.

“Rapp-it is used widely on site. It is an outstanding product for all applications. There isn’t an occasion where Rapp-it hasn’t done the job.”
