Project Overview

The Oyu Tolgoi project is one of the world’s largest known copper and gold deposits, located in Mongolia’s remote South Gobi Desert. As part of this major underground mine development, Pacific Hoseflex was contracted to manufacture and supply high-performance metallic expansion joints for critical processing and utility infrastructure.

The project required engineered components capable of performing reliably under extreme temperature fluctuations, vibration, mechanical movement, and the continuous operating demands associated with large-scale mining environments.

Challenges

Withstanding extreme temperature variations and mechanical stress in harsh desert conditions.
Managing thermal expansion, vibration, and movement across critical pipeline systems.
Maintaining system flexibility and durability under continuous heavy-duty mining operations.
Supplying precision-manufactured components that met international quality and performance standards.
Supporting project requirements in a remote location with demanding construction schedules.

Our Scope

Pacific Hoseflex manufactured and supplied a specialised package of metallic expansion joints engineered for high-pressure and high-temperature fluid systems throughout the mine’s processing and utility infrastructure.

The expansion joints were designed to accommodate thermal movement, absorb vibration, and reduce mechanical stress on connected pipework and equipment, helping protect the long-term integrity of critical systems.

Outcome

Pacific Hoseflex delivered:

Reliable compensation for thermal expansion and mechanical movement across critical pipeline systems.
Reduced stress on connected pipework, equipment, and structural components.
Durable performance in harsh conditions including dust, vibration, and significant temperature fluctuations.
Low-maintenance expansion solutions suited to a remote, high-production mining environment.
Seamless integration into critical process and utility infrastructure.
Improved system reliability, operational efficiency, and long-term asset protection.
