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: 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.

Q: 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.

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.

Juhua pipe floats deliver dependable buoyancy and stability for pipelines in marine and inland projects. Designed for durability and long service life, these floats simplify installation, reduce mechanical stress, and help maintain accurate pipeline alignment under changing water and sediment conditions.

Frequently Asked Questions (FAQ)

Q1: What are pipeline floats?

A1: Pipeline floats (also known as dredge floats or buoyancy modules) are devices attached to discharge pipes to keep them afloat on water.

Q2: How do I calculate how many floats I need for my pipeline?

A2: You need to ensure total buoyancy exceeds total weight. Calculate the combined weight of the steel/pipe itself + the weight of the material inside (e.g., slurry/water) + accessories. The floats should provide at least 20-30% more buoyancy than this total weight to keep the pipeline floating properly (usually with 1/4 of the pipe diameter above water).

Q3: How long is the warranty period?

A3: 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.

Q4: Are these floats suitable for seawater use?

A4: 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.

Q5: What sizes and specifications can be customized?

A5: We provide modular pipeline floats with internal diameters ranging from 110 mm to 1200 mm and length options from 500 mm to 2500 mm. Custom wall thicknesses, color options, and net buoyancy requirements can be engineered based on project specifications.

Q6: What is the delivery time for bulk orders?

A6: With our direct factory manufacturing capacity and optimized supply chain management, standard models can be dispatched promptly, while custom engineered production runs are scheduled efficiently to guarantee on-time global delivery.
