FT800X1100 Type Polyethylene Pipe Float

FT800X1100 Type Polyethylene Pipe Float

Product Introduction

The FT800X1100 Type Polyethylene Pipe Float is a high-performance buoyancy module engineered for heavy-duty marine dredging, sand pumping, and pipeline support applications. This model features a robust 800mm outer diameter and 1100mm length, providing exceptional flotation capacity for large-diameter pipelines in rivers, lakes, and offshore environments .

Advanced Material Construction

Each FT800X1100 float is manufactured from high-quality polyethylene (LLDPE/HDPE) through advanced rotational molding technology, creating a seamless, leak-proof outer shell . The shell is filled with high-strength closed-cell polyurethane (PU) or expanded polystyrene (EPS) foam, which provides permanent buoyancy even if the outer shell is punctured . This dual-layer construction delivers exceptional resistance to impact, corrosion, UV radiation, and harsh marine conditions .

Technical Parameters

Key Features & Benefits

1.Optimized Buoyancy Performance: The FT800X1100 delivers 600kg net buoyancy per unit, engineered to provide approximately 30% higher flotation than pipeline weight requirements, ensuring safe and reliable operation during dredging operations .

2.Exceptional Durability: The polyethylene shell offers outstanding weather resistance, environmental stress crack resistance, and an operational temperature range from -60°C to +80°C . Impact strength exceeds 31.4 KJ/m², with tensile strength greater than 12 MPa .

3.Two-Half Modular Design: Each float consists of two symmetrical halves that bolt together around the pipeline, enabling quick and easy installation without specialized tools or equipment . This design allows for convenient maintenance, repositioning, or replacement as project requirements change.

4.Corrosion-Resistant Hardware: Supplied with galvanized or stainless steel bolts, nuts, and washers that provide secure, vibration-resistant connections while resisting saltwater corrosion . This ensures long-term structural integrity in marine environments.

5.High Visibility Safety: Manufactured in bright international safety colors (typically orange or yellow) to act as warning signals to other vessels and improve visibility during day and night operations, preventing accidental pipeline collisions .

6.Non-Slip Surface Design: The exterior features an anti-skid textured surface for safe handling during installation and maintenance, with rounded corners to prevent injury .

7.Extended Service Life: The non-porous HDPE material resists marine growth, chemicals, and abrasion, lasting up to three times longer than traditional steel pontoons with virtually zero maintenance requirements .

8. Environmentally Friendly: Made from non-toxic, recyclable materials that do not pollute water quality, making them safe for freshwater and saltwater environments .

Typical Applications

*Sand Dredging & Excavation: Provides essential flotation for discharge pipelines in river and lake sand mining operations .

*Land Reclamation Projects: Supports pipelines transporting sand and slurry for coastal development and hydraulic reclamation .
