Rapp-it Pipe Repair Bandages are suitable for use on many pipe substrates, including tailings pipes that are typically used in Coal Handling Processing Plants (CHPP).

SCOPE

The customer advised that they had a leak in their tailings underflow pipe, used for transferring the smaller rejects to the tailings dam. This pipe usually has about 600kPa going through 24/7 and at times, pressures can reach up to 1000kPa. The leak was located on a bend just off the pump, which had worn through the basalt lining and the metal outer casing.

SOLUTION

The customer reduced the pressure and cleaned and roughened the damaged area. The leak was firstly stemmed with Rapp-it Steel Putty, and four Rapp-it Pipe Repair Bandages were applied. In just 30 minutes, the leak was contained and the pipe was back up and running – saving costs and downtime.
