Marine Floating Discharge Hose

About product

The marine floating discharge hose is comprised of a lining, reinforcing plies, flotation jacket, outer cover, and carbon steel fittings at both ends. Its unique integrated buoy-type flotation jacket design ensures a seamless connection with the hose, providing balanced buoyancy distribution. The closed-cell foaming material used in the flotation jacket minimizes water absorption, ensuring long-term buoyancy stability and reliability.

  • Excellent abrasion resistance and UV protection for durability in marine environments.
  • Colored indicator layer for easy visual inspection of wear levels.
  • Foam floatation casing for water absorption prevention and buoyancy.
  • High-quality, wear-resistant rubber construction for durability and reliability.
  • Customizable flange design for secure connections.
  • Flexible bending capability for adaptability in different conditions.

Product Detail

Performance Of Marine Floating Discharge Hose

The marine floating discharge hose offers excellent performance with the following features:

  • Outer cover: The hose is equipped with an outer cover that provides exceptional abrasion resistance and UV protection, ensuring durability and longevity in harsh marine environments.
  • Wearing colored indicator layer: It features a colored indicator layer that serves as a wear indicator, allowing for easy visual inspection of the hose’s condition and wear levels.
  • Single foam floatation casing: The hose is designed with a single foam floatation casing that prevents water absorption, ensuring buoyancy and maintaining the hose’s performance even in wet conditions. The hose’s emergence above water is at least 20% of the total volume, ensuring reliable floating capability.
  • High-quality, wear-resistant rubber: The hose is constructed using high-quality, wear-resistant rubber that can withstand the demanding conditions of marine applications, providing excellent durability and reliability.
  • Flange design: The hose’s flange design can be customized according to customers’ specific requirements, ensuring proper and secure connections to the equipment or piping systems.
  • Bending angle: The hose is capable of bending within a range of 0° to 45° during operation, allowing flexibility and adaptability to different working conditions.

Buoyancy Of Marine Floating Discharge Hose

The buoyancy of the marine floating discharge hose is highly customizable to cater to specific application requirements. It is denoted internationally by “SG XX,” such as “SG 1.8,” “SG 2.0,” and “SG 2.3.” The “SG XX” signifies the maximum density of the conveyed material in t/m3, indicating that the hose will not fully submerge when handling materials with that density. The buoyancy configuration is tailored to the operating environment and conveying capacity, ensuring optimal performance and preventing excessive submersion. This flexibility allows the hose to adapt to various conditions and maintain efficient buoyancy throughout its operation.

Marine Floating Discharge Hose Applications

Marine floating discharge hoses have several distinct applications:

  • Floating pipelines: These hoses are commonly used to create floating pipelines for the efficient conveyance of materials. They can be connected together to form an independent floating pipeline system, enabling seamless transport across water bodies.
  • Independent floating pipeline: Marine floating discharge hoses can function as standalone floating pipelines, eliminating the need for additional steel pipes. This application is ideal when a dedicated and flexible pipeline solution is required.
  • Spaced connection with steel pipes: These hoses can be spaced connected with steel pipes at intervals, combining the advantages of both components. This hybrid configuration offers versatility and adaptability in material conveyance, allowing for efficient transportation in diverse marine environments.
