What are pipeline floats?

Pipeline floats, also called dredge floats or buoyancy modules, are clamp-on polyethylene bodies fitted around discharge pipes to keep a dredging or water-transfer pipeline afloat, aligned and visible on the water surface.

How do I calculate how many floats I need for my pipeline?

Total float buoyancy must exceed the total weight of the pipe, the conveyed medium (water or slurry) and accessories. As a rule of thumb, floats should provide 20–30% more buoyancy than this total so the pipeline floats with roughly one quarter of its diameter above water.

Are polyethylene floats suitable for seawater use?

Yes. Polyethylene is highly resistant to saltwater corrosion, UV radiation and chemical attack, and unlike steel floats it never rusts, which is why PE is preferred in marine environments.

How long is the warranty period?

The warranty starts when the buyer hands over the goods to the investor and ends 18 months after that handover date or 12 months after the installation date, whichever comes first.

What information is needed for an accurate pipe float specification?

Provide pipe outer diameter, pipe material and wall thickness, conveyed medium and its density, pipeline length, site conditions (river, reservoir, port or offshore), required freeboard, colour or marking requirements, quantity and destination port.

Can floats and buoys be customised?

Yes. Float bodies are matched to the specified pipe outer diameter, and colour, marking and fittings can be adapted to project requirements. Custom rotomolded parts can also be produced to drawings.

Frequently Asked Questions (FAQ)

Are these pipe floats suitable for seawater use?

Yes, absolutely. Polyethylene (PE) is highly resistant to saltwater corrosion, UV radiation, and chemical erosion. They are preferred over steel floats in marine environments because they never rust.

How thick is the plastic on the floats, and what is the exact material?

All of our floats are made with rotationally molded PE (polyethylene) plastic shells, and each float features a closed-cell urethane foam filling for safety and structural rigidity. The tough PE shell handles heavy physical impacts while the foam core prevents sinking even if punctured.

What happens if a float gets pierced or damaged during operation?

Damage is very rare due to the durable construction, but if pierced, you will not sink thanks to the closed-cell urethane foam inside. You can easily replace the modular unit or perform an on-site repair using a standard HDPE plastic welding kit after draining and drying the damaged area.

Can you design customized products and dimensions for specific projects?

Yes. We provide full OEM and bespoke engineering support. Our professional technical team designs custom outer lengths, internal diameters, buoyancy ratings, and structure profiles to precisely meet your engineering drawings and job specifications.

What standard outer and inner dimensions are available?

Standard configurations include L800×W500×ID160mm, L800×W500×ID220mm, L1300×OD1300×ID500mm, and L1500×W1300×ID630mm. Tailored sizes and custom internal diameters are readily manufactured to fit your specific floating pipes.

How are these floats securely fastened to pipelines and cables?

Our modular floats are designed for versatile attachment and are compatible with high-strength stainless steel bolts, steel-textile straps, or specialized corrosion-resistant strapping systems to ensure reliable, non-slip attachment under harsh offshore waves.
