Hongruntong Marine Hose Floats are professional floatation devices developed for port operations, shipyard activities, and nearshore marine engineering where hoses and temporary pipelines require stable buoyancy, frequent repositioning, and high resistance to mechanical impact.
Manufactured using a robust HDPE outer shell combined with a closed-cell foam core, these floats ensure consistent buoyancy and excellent structural integrity. The split-type modular design enables fast installation and removal, making them particularly suitable for temporary or frequently adjusted hose layouts commonly used in ports and shipyards.

At a large commercial shipyard serving bulk carriers and container vessels up to 80,000 DWT, temporary floating hoses were routinely used for ballast water discharge, fire pipeline testing, and equipment flushing during vessel repair and maintenance.
After implementing Hongruntong Marine Hose Floats, the shipyard reported improved safety during operations, easier hose handling by work crews, and a noticeable reduction in hose wear and replacement frequency. The floats demonstrated strong durability and cost efficiency across multiple vessels and maintenance cycles.

NOTE: Customized floaters are available.
Engineered to provide sufficient lift to keep hoses afloat under full-load conditions while maintaining stable freeboard, preventing partial submersion and accelerated wear.
Thick-walled HDPE outer shell offers excellent impact resistance, protecting the internal foam core from damage and ensuring long-term structural stability in busy port environments.
Allows fast installation without disconnecting hoses, significantly reducing labor time and improving operational flexibility for dynamic port-side workflows.
All materials are corrosion-resistant and suitable for long-term exposure to seawater, oils, and common port-side chemicals, ensuring stable buoyancy over time.
Hose Floats can be designed for hose diameters ranging from approximately 200 mm to over 1,200 mm. Custom sizes are available for special project requirements.
Yes. Due to their durable construction and corrosion-resistant materials, Hose Floats can be reused across multiple projects with proper inspection.
The split-body design allows the floats to be mounted directly onto hoses without disconnecting the pipeline, reducing installation time and operational disruption.
Yes. The HDPE outer shell is UV-stabilized and designed to withstand prolonged exposure to sunlight and harsh marine conditions.
Yes. We can provide buoyancy calculations, float spacing recommendations, and technical drawings to support safe and efficient pipeline design.
