Operating Temperature Range -40°C to 80°C Dredging Pipe Floating Pipeline
Product Overview
Hongruntong Marine specializes in manufacturing high-performance Floating Pipelines (Floating Hoses) for marine, coastal, and offshore applications including dredging, offshore oil and gas transportation, aquaculture, and flood control. Our pipelines are engineered to operate stably on water surfaces, even in rough sea conditions with strong waves, tides, and variable water levels.
Constructed with a high-strength composite structure, the pipeline integrates a wear-resistant inner tube, multi-ply high-tensile steel wire reinforcement, and durable outer cover, while being equipped with integrated buoyancy layers or modular floaters to ensure reliable flotation without sinking or tilting.

Key Features
- 30+ Years Manufacturing Experience: Mature manufacturing processes and strict quality control systems ensure products meet highest industry standards
- Integrated Buoyancy System: Built-in high-density foam buoyancy layer ensures stable flotation, preventing tilting or sinking in rough seas
- Ultra-High Abrasion Resistance: Specially formulated thick rubber inner tube withstands abrasive media, extending service life by 40%
- Heavy-Duty Steel Wire Reinforcement: Multiple plies of high-tensile steel wire provide exceptional pressure-bearing capacity and vacuum resistance

Applications
- High-Pressure Buoyancy Stability: Reinforced integrated buoyancy system supports heavy pumping loads while maintaining stable flotation
- Dynamic Vessel Motion Adaptability: Superior flexibility absorbs constant movement of service vessels and crane platforms
- Marine-Grade Chemical Resistance: Formulated to handle diverse fluids including hydraulic oils, cooling fluids, and concrete grout
- UV & Weather Hardening Protection: UV-stabilized outer cover resists cracking and degradation from prolonged sunlight exposure
Frequently Asked Questions
Can your floating pipeline be used in offshore wind farm construction in rough sea conditions?
Yes, our floating pipeline is engineered with an integrated buoyancy system and robust reinforcement, ensuring stable flotation and structural integrity even in strong waves, tides, and rough open-ocean conditions, perfectly suited for offshore wind farm construction.
What fluids can the floating pipeline convey for offshore wind farm projects?
It can reliably convey hydraulic oils, cooling fluids, concrete grout, freshwater, and construction slurries—all common fluids used in offshore wind turbine installation and maintenance.
How does the floating pipeline adapt to the movement of wind farm service vessels?
With superior flexibility and anti-fatigue design, it can absorb the dynamic movement of service vessels and crane platforms, avoiding stress damage and ensuring uninterrupted fluid transfer.
Is the floating pipeline compliant with offshore wind farm engineering standards?
Yes, all our products meet stringent international standards (BV, ABS, DNV, ISO 1436), fully complying with the safety and quality requirements for offshore wind farm construction logistics.
