HDPE Dredging Pipe Floats Providing Buoyancy and Support for Discharge Hoses and Pipelines in Various Dredging Environmental Circumstances

Constructed with high-density polyethylene (HDPE) through rotational molding technology and filled with high-strength closed-cell polyurethane (PU) foam, these floats combine exceptional durability, corrosion resistance, and superior buoyancy performance. Unlike traditional steel floats, our HDPE dredging pipe floats feature a lightweight design that simplifies transportation and installation, while the integrated UV stabilizers ensure long-term resistance to harsh environmental factors such as sunlight, saltwater, and extreme temperatures (-60℃ to +80℃). Available in standard yellow, orange, or customized colors, the floats also serve as effective warning signs for nearby vessels, enhancing operational safety in busy waterways.

• Reliable Buoyancy Support: Effectively disperses the weight of dredge pipelines and the slurry inside, preventing pipeline sinking and ensuring stable floating above the water level.
• Pipeline Protection: Absorbs and reduces impact energy from vessel collisions and wave shocks, minimizing wear and damage to dredge pipelines and hoses.
• Stabilization & Guidance: Helps maintain the pipeline's designed route during dredging operations, reducing deviations caused by water flow and wave disturbances.
• Environmental Adaptability: Resists corrosion from saltwater, chemicals, and acidic/alkaline substances, making it suitable for both freshwater and marine environments.

• Inland Waterway Dredging: River and lake sediment cleaning, channel deepening, and waterway maintenance projects. Ideal for shallow water conditions and areas with frequent pipeline movement.
• Port & Harbor Construction: Port expansion, berth dredging, and navigation channel improvement. The high-impact resistance ensures durability in busy port environments with heavy vessel traffic.
• Offshore Dredging & Reclamation: Coastal reclamation, offshore wind farm foundation construction, and seabed mining. Designed to withstand rough sea conditions and strong wave impacts.
• Mine & Industrial Dredging: Tailings discharge, coal washing wastewater treatment, and industrial wastewater pumping. Corrosion-resistant properties adapt to harsh industrial environments.
• Environmental Remediation: Eutrophic lake treatment, wetland restoration, and contaminated sediment dredging. The eco-friendly materials comply with international environmental standards and do not pollute water bodies.

1. During operation, regularly inspect the float connection status. Tighten any loose bolts and replace damaged gaskets in a timely manner to prevent float slippage or water ingress.
2. Avoid collision between the floats and hard objects (such as rocks, ship hulls) to prevent damage to the HDPE shell. For high-risk areas, install additional防撞 guards if necessary.
3. After long-term use, clean the float surface to remove marine organisms, sludge, or other attachments. This helps maintain buoyancy performance and extends the service life of the floats.
4. When storing the floats, place them in a dry and ventilated area away from direct sunlight. Avoid stacking heavy objects on the floats to prevent deformation.
5. If the float shell is cracked or the internal foam is waterlogged (resulting in reduced buoyancy), replace the float immediately to ensure operational safety.
