A 14" HDPE pipe float designed for dredging in sand mining is built to support the larger pipelines used in transporting slurry, sand, and other mining materials. Here’s a detailed description:

Specifications:

• Inner Diameter (ID): 400 mm (designed to fit a 14" pipeline).
• Outer Diameter (OD): The OD would be significantly larger than the ID to provide adequate buoyancy, typically depending on the required buoyancy capacity.
• Material: High-Density Polyethylene (HDPE), known for its lightweight, impact resistance, corrosion resistance, and UV stability.
• Buoyancy Capacity: Tailored to support the larger, heavier 14" dredging pipe and the slurry load it carries. This would depend on factors like the density of the slurry being transported and environmental factors.
• Design: A two-piece clamshell design with bolted or strapped connections for secure fastening around the dredging pipe. This allows for easy assembly, installation, and removal.
• Weight: Light enough to be easily transported and installed but sturdy enough to provide reliable buoyancy.
• Applications: Used in dredging, sand mining, and slurry transportation operations where keeping the pipeline afloat is crucial for smooth operations in marine or offshore conditions.

Key Features:

• High Buoyancy: Designed to handle the weight of the 14" pipeline and the material it carries, ensuring the pipeline stays afloat during operations.
• Durability: Resistant to the harsh marine environment, including UV exposure, chemicals, and mechanical impacts from floating debris or heavy materials.
• Easy Installation and Maintenance: The two-piece design makes it easy to install around the pipeline, even in remote or offshore environments.

This type of float is critical in ensuring that larger pipelines (like the 14" pipe) remain buoyant and functional during dredging operations, minimizing downtime and facilitating efficient transportation of materials.
