Leaking new FIRE Mains Relined

Caterpillar’s state-of-the-art parts distribution facility supports the worldwide expansion of heavy industry equipment manufacturer. Multiple leaks in the new fire lines were causing the fire system to fail, putting the entire building at risk.

Work Performed

Utilising our Blueline technology, Nuflow relined multiple lengths of blue brute fire lines ranging in diameters from 262mm to 315mm. A double thickness liner was utilised as being a fire line the reline work was required to withstand pressure of up to 1700 kpa’s.

The problem

After an investigation of the fire line, it was discovered there were multiple leaks including one near a 45 degree bend and junction. This resulted in the line not being able to hold pressure, meaning should there be a fire the system would not function to full capacity.

Results

Nuflow were able to rehabilitate all lines with no disruption to surfaces or essential services.

Alternatives

An alternative to relining would have been to excavate the area and replace the pipes. This would have been very expensive, disruptive and labour intensive due to the pipes being located 4m under hardstand pavement, a surface designed specifically to support the heavy traffic flow of oversize vehicles.
