Dewatering high pressure pipe

Copper Mining Industry, Chile (2008)

Project Description:  Open copper mine with extreme temperatures ranging from −20°C to +40°C, high pressure and water hammer – impossible conditions for other types of pipes –
need to change location after a period of time, distance between the two locations is 10 km

Challenges

• Dragging over rough terrain
• High temperatures
• High pressure

Solution

PEXGOL™ pipe diameter 110 mms class 15, each unit of 300 m with no connections (

The pipes were dragged a distance of 10 km and re-assembled but no damage caused by dragging
