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.

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.

Q: 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.

The Pipe Floats with Cable Troughs are engineered for stability, durability, and safety in marine and industrial pipeline systems. Their integrated cable protection design ensures smooth operations in harsh environments such as offshore projects, ports, and water transportation systems.

Frequently Asked Questions (FAQ)

Q: How long is the warranty period?

A: The warranty period begins on the date the buyer hands over the goods to the investor and ends on the first 18 (eighteen) months after the buyer's handover date, or on the first 12 (twelve) months after the installation date, whichever comes first.

Q: Are these floats suitable for seawater use?

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

Q: How thick is the plastic on the floats? Precisely what is the material?

A: All of our floats are made with PE (polyethylene) plastic shells, each float has a closed-cell urethane foam filling for safety and structural rigidity. The PE shell is a super tough material that will take a beating and the foam filling stops you from sinking if you do manage to puncture a float.

Q: What happens if one breaks?

A: In the years of us selling our floats to industrial and recreational customers, very few tell us that they have punctured a float. Our floats really are tough as nails, but if you have the misfortune of piercing one, you can either easily replace the float, or repair it, but when the damage happens, you won't sink due to the non-water absorbing urethane foam inside each float. If you choose to repair a float, remove it from the pipe (or at least pull the craft out of the water), let it drain in a dry area for a couple days, and use a HDPE plastic welding kit. This is a kit that comes with a special electric soldering iron-type tool and some plastic welding rod.

Q: What are the standard dimensions and modular models available?

A: Available standard models include L800 × OD500 × ID160, L800 × OD500 × ID220, L1500 × OD1300 × ID630, and L1300 × OD1300 × ID500, designed to accommodate various pipeline diameters and buoyancy requirements.

Q: Can dimensions, buoyancy, and colors be customized?

A: Yes, color (such as standard orange, black, or custom colors), buoyancy, structure, and attachment methods (such as steel, steel-textile, or customized strap fastening systems) can be tailored to meet client project specifications.
