Faced with badly corroded pipework around central saltwater cooling towers, Rapp-it was the preferred repair and protection method for this challenging environment.

SCOPE

This repair was conducted on exposed pipework around a large ammonia chiller vessel. One of the critical challenges involved repairing pipe sections exposed to extreme temperatures, including frozen ammonia lines ranging from –30°C to –40°C.

SOLUTION

The customer used Rapp-it Steel Putty and Rapp-it Pipe Repair Bandages to stem the leak and put the vessel back in production. Following direct communication between the inspection team and Rapp-it’s technical support, the repair has consistently withstood both the mechanical demands and harsh thermal conditions.
