The Challenge

The Meridian mine (Faena El Peñón) required the installation of a line for the drainage of high-pressure water from the lower level of the mine, passing through the vertical ventilation chimney with a height of 150 meters, continuing through the interior of the mine until an outdoor pool.

Pexgol Solution

The client decided to install 800 m of Pexgol pipes in three di erent sizes:
Pexgol 160 mm (6”) Class 15, 160 mm (6”) Class 19 and 200 mm (8”) Class 26.7.
The installation was very simple:

Lifting was carried out in the ventilation chimney.
Mechanical connections were used that did not require special tools for installation.
In the upper area the pipes were placed on supports provided by the mining company.

Pexgol was selected due to its capabilities:

Possibility of supply in long lengths minimizing the connections to only 4.
Ability to withstand the drag of more than 5 km from outside to the final assembly point inside the underground mine.
Ability to withstand creep involved in vertical mounting of 150 meters.
