Marine Suction Dredge Hose

About product

The marine suction dredge hose is specifically designed for the conveyance of silt, gravel, and other materials in conjunction with a dredger. It effectively utilizes negative pressure to suction the mixture of silt and water. Commonly used in combination with rubber flange/steel backing flange and double action flange fittings, these hoses are available in various sizes to suit specific applications. They possess exceptional qualities such as 100% vacuum capability and high implosion pressures. Additionally, for compatibility with gimbals and the ladder of cutter dredgers, suction hoses with small bending radius can be provided.

  • Facilitates efficient suction and transfer of materials during dredging operations.
  • Ensures a secure and reliable connection with other components.
  • Allows flexibility and movement, accommodating variations in equipment positioning.
  • Designed to withstand abrasive materials and harsh marine conditions.
  • Suitable for various dredging applications and projects.

Product Detail

 The Flange Type Of Marine Suction Dredge Hose

Marine suction dredge hoses are commonly equipped with different flange types to ensure secure connections and efficient material conveyance. Here are two flange types often utilized:

  • Rubber Flange/Steel Backing Flange: This flange type combines the flexibility of a rubber flange with the structural support of a steel backing flange.
  • Double Action Flange: The double action flange is designed to enhance sealing capabilities.

Advantage Of Rubber Flange/Steel Backing Flange

  • Secure and Reliable Connection: The combination of rubber flange and steel backing flange provides a secure and reliable connection between the marine suction dredge hose and other components, minimizing the risk of leaks or disconnections during dredging operations.
  • Flexibility and Movement: The rubber flange allows for flexibility and movement, accommodating variations in positioning and alignment of the dredging equipment. It helps prevent stress on the hose assembly and allows for easier installation and removal.

Advantage Of Double Action Flange

  • Enhanced Sealing: The double action flange provides enhanced sealing capabilities due to its double-sided design. It features rubber seals on both sides, offering a tighter seal and minimizing the chances of leakage during dredging operations.
  • Leakage Prevention: The double action flange helps prevent leaks, even in situations where there may be slight misalignment or movement between the hose and the connected components. It provides an additional layer of protection against potential leakage.
