Marine Composite Hose

About product

Marine composite hose refers to a type of transfer hose specifically designed and used for marine applications. It shares many of the characteristics and performance capabilities of general composite hose.

This marine hose is built to withstand the demanding conditions encountered in marine environments. They excel in handling a wide range of liquids and gases, including valuable, high-temperature, flammable, explosive, corrosive, and environmentally polluting substances, as well as oil and chemicals.

Similar to composite hose in general, marine composite hose is constructed using multiple layers of different materials, which contribute to its exceptional durability and reliability. The multi-layered sealing structure ensures that the hose maintains its integrity, even in harsh and challenging conditions, providing resistance against rupture and leakage.

  • Designed for transferring various fluids in marine operations.
  • Handles gasoline, diesel, crude oil, and chemical liquids.
  • Remains highly flexible in freezing weather conditions.
  • Lightweight and easy to handle and transport.
  • Suitable for dynamic marine environments with movement and vibrations.
  • Resistant to high temperatures, low temperatures, aging, deformation, and corrosion.
  • Specially designed inner layer with exposed internal spiral metal for static dissipation functionality.

Product Detail

Marine Composite Hose – Transfer Hose For Marine Oil Project

This transfer hose is specifically designed to handle the transfer of various fluids commonly found in marine operations, such as gasoline, diesel, crude oil, and different chemical liquids. It remains highly flexible even in freezing weather conditions, ensuring ease of use and efficient fluid transfer.

The composite hose for transfer offers several advantages. The transfer hose is lightweight, making it easy to handle and transport. Its strength and flexibility make it suitable for use in dynamic marine environments where movement and vibrations are common. This marine hose is designed to be sensitive to use, allowing for efficient and precise handling during operations.

Additionally, the transfer hose for oil projects exhibits excellent resistance to high temperatures, low temperatures, aging, deformation, and corrosion, ensuring its longevity and reliability in marine applications. This marine hose also features a specially designed inner layer with exposed internal spiral metal, which provides reliable static dissipation functionality, reducing the risk of static electricity buildup.

Construction Of Marine Composite Hose

The construction of the composite hose typically consists of three main components: the inner wire, the liner, and the outer wire. Here is a breakdown of each component:

  • Inner Wire:
    The inner wire of the transfer hose is made of high-tensile heavy hot-dip galvanized steel wire. This inner wire provides structural strength and stability to the hose. It helps maintain the hose’s shape and integrity, especially under pressure and during fluid transfer operations. The hot-dip galvanized coating on the steel wire enhances its corrosion resistance, ensuring durability in marine environments.
  • Liner:
    The liner is the layer that comes into direct contact with the fluid being transferred. The liner is typically made of specialized high-tensile polypropylene fabrics and films in a composite hose for marine oil transfer. Polypropylene is known for its excellent chemical resistance and low moisture absorption properties. The combination of high-tensile fabrics and films provides enhanced strength and resistance to tearing, ensuring the integrity of the transfer hose and preventing leakage.
  • Outer Wire:
    Similar to the inner wire, the outer wire is also made of heavy hot-dip galvanized steel wire. The outer wire provides an additional layer of reinforcement and protection to the transfer hose. It helps to withstand external stresses, including abrasion, impact, and environmental factors. The hot-dip galvanized coating on the outer wire enhances its corrosion resistance, ensuring longevity in marine conditions.

Advantage Of Marine Composite Hose

Marine Composite Hoses offer several advantages that make them well-suited for marine applications. Here are the key advantages:

  • Lightweight: With the lightweight design, the transfer hose is easy to handle, transport, and install. Its lighter weight compared to traditional marine hose reduces the physical strain on operators and simplifies logistics.
  • Good Flexibility: These transfer hoses exhibit excellent flexibility, allowing them to bend freely without the limitation of working space. This flexibility enables easy maneuverability and efficient fluid transfer operations, even in confined areas or complex routing.
  • Positive/Negative Pressure Resistance: The composite hose is designed to withstand both positive and negative pressures effectively. It can handle the forces generated during fluid transfer operations, providing reliable performance and preventing leaks or bursts.
  • Temperature Resistance: The composite hose for oil transfer has good temperature resistance, allowing it to maintain its performance characteristics across a wide range of temperatures. The transfer hose can withstand high-temperature fluids as well as remain flexible and functional in low-temperature environments.
  • Oil and Chemical Resistance: Marine Composite Hoses have excellent resistance to oils and chemicals. They can handle a variety of fluids, including petroleum products, without degradation or loss of performance. The specialized materials used in the hose construction provide resistance to chemical corrosion, ensuring their longevity and reliability.
  • Static Dissipation: Marine Composite Hoses are designed with good static dissipation properties. They effectively dissipate static electricity buildup, reducing the risk of sparks or electrical discharge in potentially hazardous environments.
  • Hydraulic Shrinkage Forming: This marine hose features hydraulic shrinkage forming, which creates a tight seal and enhances the overall sealing performance. This ensures that fluid transfer operations are secure, minimizing the risk of leaks or spills.
  • Seawater Corrosion Resistance: Marine Composite Hoses exhibit excellent resistance to corrosion caused by seawater. The materials used in their construction, including galvanized steel wires, are specifically chosen to withstand the corrosive effects of saltwater environments, ensuring long-term durability.

Marine Composite Hose Applications

Marine Composite Hoses find extensive applications in the marine industry for the suction and discharge of petroleum products during ship-to-ship and ship-to-shore operations. Here are some specific applications of Marine Composite Hoses:

  • Ship-to-Ship Transfers: Marine composite hoses are commonly used to transfer petroleum products, such as oils and aromatics, between two ships at sea. These hoses enable efficient and safe transfer operations, ensuring the seamless movement of fluids between vessels.
  • Ship-to-Shore Transfers: Marine composite hoses are also utilized for transferring petroleum products from ships to onshore facilities, such as terminals or storage tanks. They enable the efficient offloading of oils, ensuring a smooth transfer process from the vessel to the shore.
  • Oil Transfer Operations: Composite hoses, utilized as transfer hoses, are well-suited for the handling of a wide range of oils, including crude oil, diesel, gasoline, and other petroleum-based products. They can withstand the suction and discharge of these fluids, making them ideal for oil transfer applications in marine environments.
  • Aromatics Transfer: In addition to oils, the composite hoses are designed to handle aromatic substances. Aromatics, such as benzene, toluene, and xylene, can be safely transferred using these hoses, ensuring the efficient movement of these volatile liquids.
  • Positive and Negative Pressure Applications: These marine hoses are designed to handle both positive and negative pressures. They can effectively transfer fluids under pressure or vacuum conditions, making them versatile for various marine applications.
