Floating Collar Double Shell Structure For Balance And Safety
Secure Bolt Connections
Introduction
This HDPE Pipe Float is designed for heavy-duty floating pipeline
systems in demanding marine and industrial settings. It features a
double-layer shell made from tough polyethylene and an internal
foam core that prevents sinking in case of damage. The structure
offers exceptional resistance to impact, wear, and environmental
stress. Its compact design ensures excellent load distribution and
long-term performance. Widely used in dredging and offshore oil
transport, this float supports pipelines ranging from 4 to 48
inches in diameter and is available in custom colors and
configurations.

Features
High Buoyancy and Stability
Each hose float is engineered to deliver exceptional buoyancy,
ensuring that even heavy-duty pipelines remain securely afloat. The
design balances weight distribution across the water surface,
minimizing pipe sagging or twisting. This improves operational
safety and efficiency, particularly in long pipeline installations
over water.
Durable HDPE Outer Shell
Constructed from high-density polyethylene (HDPE), the float offers
superior resistance to impact, abrasion, and environmental stress.
This material is widely recognized for its long service life,
chemical resistance, and UV stability, making it ideal for harsh
marine and industrial environments. The tough shell prevents
cracking even under repeated collisions or pressure.
Foam Filled Safety Core
The interior is filled with closed-cell polyurethane or EPS foam,
providing a secondary layer of flotation. In the event the outer
shell is punctured or damaged, the float will continue to function
and support the pipeline, reducing the risk of equipment loss or
downtime. This feature is essential for high-risk or remote
operations.
Quick and Easy Installation
The float consists of two symmetrical halves joined by
high-strength bolts, allowing for rapid installation or removal
without special tools. This design reduces setup time and labor
costs, especially in field conditions. Custom clamping systems are
available to match different pipe diameters, ensuring a tight and
secure fit.
Applications
► Firefighting water supply
► Flood response operations
► Emergency dewatering
► Environmental spill containment
► Floating cable protection
