Client Victorian West Gate Tunnel Project
Sector Infrastructure – Road & Tunnel Construction
Project Overview
The West Gate Tunnel is one of Victoria’s largest infrastructure undertakings, designed to ease congestion and improve transport efficiency across Melbourne’s western corridor. With long tunnel sections and extensive underground works, the project required resilient fluid transfer systems capable of withstanding structural movement, vibration, and fire safety demands. Pacific Hoseflex was selected to supply specialised hose assemblies that met these critical performance requirements.
Our Scope
Pacific Hoseflex manufactured and supplied flexible stainless steel assemblies designed to provide long-term reliability and safety under challenging tunnel conditions:
-
Vitalflex® Seismic Joints (for Fire Systems)
Engineered to accommodate structural movement during seismic activity or settlement, these joints ensured uninterrupted operation of the tunnel’s fire suppression systems — a mission-critical requirement in underground infrastructure. -
Vitalflex® Flexible Hoses
Supplied for various applications requiring vibration absorption, alignment correction, and flexible connection in confined or high-stress areas of the tunnel.
Challenges
-
Supporting fire systems with flexible components capable of maintaining integrity during seismic movement or structural shifts.
-
Ensuring compliance with strict safety codes for critical infrastructure and public safety systems.
-
Designing and delivering customised hose solutions to integrate seamlessly within the tunnel’s complex mechanical systems.
Outcome
Pacific Hoseflex provided:
-
Seismic-rated hose assemblies to maintain the integrity of fire suppression systems in the event of movement.
-
Durable, stainless steel hoses that resist corrosion and wear in high-stress tunnel environments.
-
Reliable performance and easy installation, ensuring construction timelines and safety requirements were met.
-
Peace of mind for contractors and engineers through locally manufactured, ISO-certified components.
