Hong Kong-Zhuhai-Macao Bridge

Project Background Analysis and Core Challenges:
The Hong Kong-Zhuhai-Macao Bridge is the world's longest sea-crossing bridge, hailed as one of the "Seven Modern Wonders of the World." Its undersea tunnels, artificial islands, and bridge management facilities impose the most stringent requirements on pipeline systems:

Extreme Environmental Corrosion: The high-humidity, high-salinity marine environment presents an epic challenge to the corrosion resistance of pipeline systems, demanding products with an exceptionally long design life.

Exceptionally High Safety and Reliability Standards: The fire protection, water supply, and gas systems (e.g., emergency power generation) must adhere to a "zero-failure" standard. Any leakage or failure could lead to catastrophic consequences and significant social impact.

Seismic and Deformation Resistance: Located in a coastal area, the bridge must account for structural deformations caused by geological activities and water flow impacts. The pipeline connection system must possess excellent seismic and anti-flexural deformation capabilities.

Full Life-Cycle Cost: For a century-long project, the initial procurement cost is not the sole consideration. The durability and low maintenance cost of the products are critical, requiring an extremely low full life-cycle cost.

KANAIF Group’s Ultimate Solutions:

Facing world-class challenges, KANAIF Group adopts enterprise standards that exceed national requirements, providing "ultimate safety and ultimate durability" solutions tailored for this mega project:

I. Ultra-Corrosion-Resistant Product System Customized for Marine Environments

Fire Protection System Solutions:
Provide high-performance epoxy-coated pipe fittings, hot-dip galvanized pipe fittings, and stainless steel pipe fittings. Key indicators such as coating thickness, adhesion, and salt spray resistance hours far exceed conventional standards, ensuring decades of rust-free and failure-free performance in the corrosive marine environment. This guarantees the absolute reliability of the bridge and tunnel fire protection systems.

The flexible characteristics of the grooved connection system effectively absorb structural deformations, ensuring pipeline safety.

Water and Drainage System Solutions:
Supply a full range of ductile iron pipe fittings with internal and external epoxy ceramic coating or special-coated pipe fittings for the water supply and drainage systems of the bridge and artificial islands. The products feature smooth and wear-resistant inner walls and extremely high external corrosion resistance, effectively resisting chemical corrosion from seawater and soil, ensuring water quality and ultra-long system life.

Gas and Special Gas System Solutions:
Provide seamless forged high-pressure pipe fittings for emergency power generation and other facilities on the bridge. These fittings employ special sealing designs and increased wall thickness, undergoing 100% non-destructive testing and ultra-high-standard pressure tests to eliminate any leakage risks, safeguarding the bridge’s energy backup system.
