Marine Chemical Discharge Hose

About product

A marine chemical discharge hose is a type of transfer hose specifically designed to handle a wide range of chemical products, including acids, alkalis, and alcohols. It is constructed with materials that offer resistance to various chemicals, making it suitable for demanding applications.

The chemical hose is designed to be flexible and lightweight, allowing for easy handling and maneuverability. Its softwall construction provides flexibility without sacrificing strength, enabling it to withstand the pressures associated with chemical discharge.

  • Transfer of chemicals between ships and shore facilities, ensuring safe and efficient unloading/loading.
  • Discharging chemicals on offshore platforms and rigs, withstanding harsh environments.
  • Management of ballast water, facilitating the discharge of treated water to prevent environmental contamination.

Product Detail

Marine Chemical Discharge Hose Application

The marine chemical discharge hose is commonly used in various applications where the safe and efficient transfer of chemicals is required. Some of the specific applications include:

  • Ship-to-Shore Transfer: The transfer hose is used for transferring chemicals, such as acids or alkalis, between ships and shore facilities. It enables the safe and efficient unloading or loading of chemicals onto vessels, ensuring proper containment and minimizing the risk of spills or environmental contamination.
  • Offshore Platforms and Rigs: The transfer hose for chemical products is employed in offshore operations, including oil and gas platforms or drilling rigs. It facilitates the discharge of chemicals used in various processes, such as drilling mud, production fluids, or chemical treatments. The hose’s chemical resistance and durability are crucial in withstanding the harsh offshore environment.
  • Ballast Water Management: Ballast water is essential for maintaining the stability of ships. However, it can carry invasive species that may harm marine ecosystems. The marine chemical hose is used in ballast water management systems to discharge treated ballast water, ensuring compliance with environmental regulations and preventing the spread of harmful organisms.
  • Tank Cleaning: Ships often require thorough cleaning of tanks and compartments to remove residues and prepare for cargo changes. The marine chemical discharge hose assists in the discharge of cleaning solutions, solvents, or detergents used in tank cleaning operations, ensuring effective cleaning and preventing cross-contamination.
  • Bilge Water Discharge: The chemical hose is utilized in the discharge of bilge water, which accumulates in the lower parts of ships and contains a mixture of water, oil, and other pollutants. It helps transfer the bilge water to appropriate treatment or disposal facilities, facilitating compliance with environmental regulations.
  • Chemical Spill Response: In the event of a chemical spill or emergency, the marine chemical discharge hose can be deployed to contain and control the spill. It enables the transfer of chemicals for proper containment, cleanup, or disposal, minimizing the impact on marine ecosystems.

Transfer Hose Construction – Marine Chemical Hose

  • Tube: The innermost layer of the transfer hose is made of black, smooth EPR (Ethylene Propylene Rubber) rubber compound. EPR rubber offers excellent resistance to a wide range of chemicals, including acids, alkalis, and alcohols. The smooth surface of the tube allows for efficient flow of the chemical products while minimizing friction and pressure drop.
  • Reinforcement: The hose is reinforced with high-strength synthetic cord materials. These reinforcement layers, typically made of textile or synthetic fibers, provide the hose with structural integrity, strength, and pressure resistance. The reinforcement helps the hose withstand the forces exerted during chemical discharge operations and prevents the hose from collapsing or bursting under high-pressure conditions.
  • Cover: The outer layer of the chemical hose is made of black, smooth EPR rubber compound with a wrapped finish. This cover protects the hose from external factors such as weathering, ozone, and chemical exposure. The EPR rubber compound used in the cover provides excellent resistance to these elements, ensuring the long-term durability and performance of the hose.
