Client Oyu Tolgoi Project – South Gobi Desert, Mongolia
Sector Mining – Copper & Gold Extraction
Project Overview
The Oyu Tolgoi project is one of the world’s largest known copper and gold deposits, located in the remote South Gobi region of Mongolia. As part of this multi-billion-dollar underground mine development, Pacific Hoseflex was contracted to supply high-performance expansion joint solutions that could withstand the extreme temperature fluctuations, vibration, and movement typical of large-scale mining operations.
Our Scope
Pacific Hoseflex manufactured and supplied a suite of metallic expansion joints engineered for high-pressure and high-temperature fluid systems within the processing and utility infrastructure of the mine.
-
Metallic Expansion Joints
Designed to absorb thermal expansion, vibration, and mechanical movement in critical pipeline systems — ensuring long-term reliability and protecting structural integrity in a remote, heavy-duty mining environment.
Challenges
-
Withstanding extreme temperature variations and mechanical stress in remote desert conditions.
-
Maintaining system flexibility and durability in large-scale mining infrastructure with continuous, heavy-duty operation.
-
Supplying precision-manufactured components to meet international quality and performance standards under tight construction schedules.
Outcome
Pacific Hoseflex’s metallic expansion joints delivered:
-
Reliable compensation for thermal and mechanical movement, reducing stress on connected systems.
-
Durability under harsh conditions, including dust, vibration, and temperature swings.
-
Minimal maintenance requirements, ideal for remote, high-production mining environments.
-
Seamless integration into critical process infrastructure, supporting operational efficiency and safety.
