AGRU Chile Provides a Long-Term Solution for One of the World’s Largest Copper Producers
One of the world’s largest copper producers faced significant problems in the cooling tower circuit of its sulfuric acid plant and turned to AGRU Chile for a reliable and long-term solution.
The existing carbon steel pipes were heavily corroded both inside and out. Severe incrustations caused considerable pressure losses due to reduced inner diameter and increased surface roughness. Additionally, leaking weld joints led to overheating of pumps and motors, resulting in increased vibrations throughout the piping system and its supporting structures.
These issues caused frequent shutdowns and rising operational costs, making the continued operation of the plant economically inefficient. To address these challenges, AGRU Chile recommended the use of PE 100-RC piping systems. PE 100-RC is a next-generation polyethylene resin known for its exceptional durability and corrosion resistance.
Made entirely from virgin resin, PE 100-RC offers high resistance to environmental impacts, slow crack growth, and aggressive media, making it ideal for demanding industrial applications. Thanks to its smooth surface, PE 100-RC significantly reduced pressure losses, prevented incrustations, and minimized system vibrations. Furthermore, the material is significantly lighter than steel, allowing for faster, safer, and more efficient installation.
The switch to PE 100-RC piping systems resulted in a substantial extension of the cooling tower system’s service life and boosted overall productivity of the now maintenance-free plant. This solution not only reduced operating costs but also provided a future-proof and sustainable approach to plant operation.
