Custom Poly Floats Supplier & Products

Pipeline floats (also commonly designated as dredging floats, pipeline pontoons, or HDPE buoyancy modules) are rotationally molded split polyethylene bodies designed to clamp around offshore, riverine, or mining pipeline sections. Their primary mechanical duty is supporting the combined deadweight of the conduit and the moving internal medium (such as dense slurry, tailings, or seawater), maintaining alignment, eliminating seabed drag friction, and preventing excessive pipe joint stress under swell conditions.

Buoyancy sizing must never be evaluated against an empty pipeline. It requires aggregating: (1) Total dry pipe weight per meter, (2) Total weight of internal fluid when running at peak design specific gravity (e.g., up to 1.6 kg/L for abrasive mining tailings), (3) Flange couplings, nuts, bolts, and cable harnesses. Standard hydrodynamic specifications mandate an additional 20% to 30% buoyancy reserve factor, ensuring roughly one quarter to one third of the pipe's upper diameter stays visible above water.

Unlike steel floats, virgin polyethylene cannot rust or develop electrolytic pinhole galvanic corrosion in hypersaline oceanic conditions. Poly floats eliminate recurring paint stripping, sandblasting, and drydock maintenance. Furthermore, rotational LLDPE has natural elasticity; it absorbs dynamic wave shock and impact from workboats without permanent denting, cracking, or loss of internal sealed displacement.

To provide an exact engineering recommendation and price list, our technical team requires: (1) Outer diameter (OD) and material (HDPE, steel, rubber hose) of the pipe, (2) Fluid slurry density / specific gravity, (3) Total pipeline distance and expected site dynamics (open sea, protected basin, swift river current), (4) Cable trough requirements if electric or signal lines ride the pipeline, (5) Desired freeboard margin, and (6) Delivery destination port for export freight optimization.

Our warranty covers 18 months from the date of final cargo handover to the project investor or 12 months from the date of operational deployment, whichever milestone occurs first. Under normal atmospheric and marine exposure conditions, UV8-stabilized virgin rotomolded shells exhibit an operational service lifespan typically exceeding 8 to 15 years, easily transferable across multiple project lifecycles.

Yes. Beyond our standard internal tooling for pipe diameters from OD 110 mm up to OD 1200 mm+, Juhua maintains an in-house aluminum and steel mold fabrication division. We routinely produce bespoke offshore mooring buoys, subsea tie-in cradles, specialized water barrier attachments, floating pontoons, and liquid storage tanks matching private label OEM/ODM design prints.
