Description
Dredge hoses provide critical support for cutter suction dredgers, trailing suction hopper dredgers, and other dredging vessels.
Built for high-pressure and high-abrasion applications, they often include replaceable wear-resistant liners and external flotation layers.
They function efficiently in both calm and turbulent waters, offering a reliable conduit for material transport under varying conditions.
( Case: A large river dredging project in Brazil aimed to deepen navigation channels and required hoses that could withstand constant movement and sharp sediment particles.
The dredging company deployed flexible suction hoses with integrated float collars and high-abrasion rubber interiors. The result was smoother operations with 30% less downtime and significantly improved sediment handling capacity. )

Features
Shock and Vibration Absorption
Reduces mechanical stress between dredger and pipeline system, minimizing damage caused by waves or pump surges.
Easy Connection with Flanges or Couplings
Standard or customized end fittings ensure secure, leak-free connections and fast assembly on site.
Replaceable Wear Sleeves or Liners
Extends hose lifespan by allowing inner liner replacement instead of full hose replacement.
Resistant to High Internal Pressures
Built to handle both suction and discharge pressure without compromising structural integrity.
Applications
Environmental Dredging
Employed in cleaning polluted sediments from lakes, rivers, or harbors. The hoses ensure safe transport of contaminated material without leaks.
Hydraulic Sand Pumping
Used in combination with dredge pumps for sand mining, river sand pumping, and shore feeding systems, enabling effective material movement over long distances.
Offshore Dredging Operations
Ideal for deep-sea or offshore projects such as pipeline trenching, subsea excavation, or seabed leveling. Floating and submerged hoses are both applicable.
Advantages
Resistance to Abrasion and Corrosion
Built to handle highly abrasive materials like sand, mud, gravel, and silt in harsh marine environments.
Global Project Experience
Our hoses have been installed in major dredging projects across Europe, Southeast Asia, Africa, and the Middle East.
Short Lead Times and Fast Delivery
Efficient production processes ensure on-time delivery even for urgent or large-scale orders.
OEM ODM Services Available
Flexible cooperation models to meet brand and specification needs of international partners.
FAQ
1. Are your hoses resistant to UV and saltwater?
Absolutely. The outer layer is formulated to resist weather, UV rays, and seawater corrosion.
2. Can the hoses float on water?
Yes, we offer floating dredge hoses with built-in buoyancy foam for offshore applications.
3. What is the service life of a dredge hose?
Service life depends on usage but typically ranges from 1 to 5 years under normal dredging conditions.
4. Do you conduct pressure testing before delivery?
Yes, every hose undergoes hydrostatic pressure testing to ensure safety and quality compliance.
