The HDPE Floating Pipe Pontoon is a durable buoyancy device designed to support pipelines on water surfaces during dredging, slurry transport, and offshore construction.
Manufactured from rotational molded high-density polyethylene (HDPE), the outer shell is seamless, waterproof, and highly resistant to impact, UV radiation, saltwater, and chemicals.

HDPE Floating Pontoons are engineered to maintain the correct floating position of pipelines and reduce mechanical stress caused by waves, current flow, and water level changes.

They help to:

• Keep pipelines evenly floating above water
• Stabilize long-distance slurry and sand pipelines
• Protect pipes from corrosion and seabed wear
• Absorb vibration and wave impact
• Prevent pipeline deformation and joint leakage
• Improve project safety and continuity

• River and harbor dredging pipelines
• Offshore sand mining and land reclamation systems
• Subsea pipeline installation support
• Mining tailings transportation lines
• Industrial wastewater floating discharge pipelines
• Temporary marine pipeline construction projects
• Floating water supply pipelines

• Select suitable pontoon size according to pipe diameter and weight.
• Place the two shell halves around the pipeline.
• Secure tightly with stainless steel bolts or straps.
• Arrange pontoons evenly along the pipeline.
• Test buoyancy balance before full operation.
• Launch the pipeline into water and monitor stability.
• Correct spacing ensures long-term safe performance.

• Tailor-made design for each project
• Strict quality inspection
• Stable export supply
• Professional technical support
• Competitive pricing and fast delivery
