CASE STUDY

Hydroelectric Power Station Case Study

Rapp-it is suitable for use on corroded fluid lines, water reticulation pipelines and outflow pipes widely used in hydro-electrical power stations.

Scope

The customer had an overhead leak in a 100mm water main line. The pipe required urgent repair, as the damaged area was dangerously close to electrical conduits, creating a safety hazard.

Solution

The customer reduced the line pressure, then cleaned and roughened the damaged area. The leak was plugged with Rapp-it Steel Putty and Rapp-it Pipe Repair Bandages (100mm x 4.8m) applied over the top. The line was fully functional 30 minutes after application.

“We recently applied the Rapp-it bandage repair kit to a leaking 4-inch water main pipe. Upon return to service, no leakage was detected, and the water main line has remained in service — allowing us to long-term budget plan a replacement of this section instead of an unplanned budget cost and replacement.”
