The Challenge
A leading mining operation focused on nickel and cobalt extraction and refining in Madagascar, faced a critical challenge: ensuring a reliable water supply to its pulp plant. This required building a 6-kilometer pipeline from the nearest river to the plant.
Although the project design seemed straightforward, two key challenges emerged:
- High Pressure Requirements: With a height difference of 160 meters and friction losses across the 6-kilometer distance, the pipeline needed to withstand pressures of up to 28 bar.
- Project Urgency: The plant was running out of water, meaning the project had to be executed quickly — from pipe supply to installation — with limited resources.
The Solution
Pexgol provided an ideal solution for this project by supplying 280 mm (10”) pipes in classes 30, 24, 19, and 15. These pipes were selected due to their ability to handle high pressures, flexibility, and ease of installation. Additionally, they were supplied in long coils of 100, 200, and 300 meters, which significantly reduced the number of required connections.
The fitting system used included electrofusion couplings, flared ends, and loose flanges, ensuring secure and quick connections. Pexgol’s technical support covered the entire process, from design to on-site installation, including training and tools to optimize the project’s execution.
Ambatovy evaluated alternative solutions such as steel flexible pipes with PE coatings but ruled them out due to long delivery times and the need for specialized installation tools. Pexgol proved to be the most efficient and viable solution, providing a fast, tailored response to the client’s needs.
Pexgol’s performance in this project highlights its ability to overcome technical and logistical challenges in demanding conditions.
