Polyethylene PE Floating Buoy & Float Ball​

About product

The float buoy is made primarily from medium- to high-density polyethylene (MDPE/HDPE), with a density range of 0.926–0.953 g/cm³. This material offers excellent toughness, impact resistance, and low-temperature durability, effectively withstanding collisions from floating debris, wave impact, and long-term UV exposure.

Utilizing advanced rotational molding technology, the PE floating buoy is manufactured in a single seamless piece without any welding or joints. This ensures structural integrity, uniform stress distribution, and high resistance to cracking or damage during operation. The interior is filled with high-strength polyurethane foam or closed-cell EPS foam (density ≥ 35kg/m³), providing stable and reliable buoyancy. Even if the outer shell is partially damaged, the float remains buoyant, ensuring the safe operation of the pipeline system.

Marine PE Floating Buoy, Body & Float Ball​ for Sale

Zava Marine specializes in the R&D and manufacturing of marine engineering equipment. Our polyethylene float buoy series are widely used in offshore reclamation, river dredging, underwater pipeline laying, and water surface pipeline projects across oceans, rivers, and lakes. Designed to meet demanding construction needs, our products offer strong buoyancy, corrosion resistance, lightweight construction, and easy installation, earning broad recognition from clients both domestically and internationally.

Polyethylene Floating Buoy & Body Performance

  1. Superior Buoyancy Capacity: Each polyethylene float buoy & ball unit is custom-matched to pipe diameter, flow requirements, and water conditions, delivering high and stable buoyancy that keeps pipelines level and secure even under wave and current forces.
  2. Excellent Environmental Adaptability: PE Floating Buoy ballcan operate in extreme conditions, with a working temperature range of -60°C to 80°C, making them suitable for cold highlands, tropical marine areas, and chemically aggressive environments.
  3. Corrosion Resistance & Maintenance-Free: Designed to operate in saltwater, brackish water, acid/alkaline media, or polluted water bodies, the floating buoys contain no metallic parts, making them entirely rust-free and maintenance-free, thereby lowering life-cycle costs.
  4. Eco-Friendly Design: All materials comply with EU RoHS environmental standards. No toxic substances are released, ensuring no pollution to water ecosystems. Both the PE shell and foam core are fully recyclable, supporting green and sustainable infrastructure.
  5. Easy Installation & High Construction Efficiency: The modular structure, lightweight design, and standard pipe holes with bolted connections make field installation quick and easy. The floating ball can be assembled on-site or onboard, significantly boosting construction efficiency and safety.
