These conditions place significant demands on pipeline performance. Abrasive slurries cause internal wear, while aggressive chemistry and variable pH drive accelerated corrosion. High pressures, flow fluctuations and long distances further increase system stress, elevating the risk of leakage, failure and costly downtime.

As a result, pipe fittings play a critical role in maintaining system integrity – ensuring secure connections, accommodating movement and enabling efficient maintenance. Poorly specified fittings can lead directly to operational failure, whereas well-engineered solutions improve reliability, protect assets and support long-term performance.

Supporting Mining Operations at Altitude

This capability is demonstrated at Codelco’s Andina Mine in Chile, one of the world’s largest copper mining operations located 4,000 metres above sea level in the Andes.

As part of a major expansion project to increase production capacity, Viking Johnson supplied 116 large diameter dedicated couplings to support the pipeline network delivering essential water to the site. Operating in a high-altitude, high-demand environment, the pipeline infrastructure required robust, reliable connections capable of withstanding continuous pressure and challenging conditions.

The use of Large Diameter mechanical couplings provided secure, leak-tight joints while supporting efficient installation and long-term performance across a critical system.
