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
