Dredging Rubber Hose Project Case Studies

Indonesia Port Dredging Project

Project Background

This project was carried out for port channel expansion and maintenance dredging. The contractor needed to transport high-density slurry and sand mixture over a long distance to the designated reclamation area. Due to the harsh offshore environment, the dredging hoses were required to provide excellent abrasion resistance, flexibility, and seawater corrosion resistance.

Customer Feedback

The floating hose system provided stable performance in offshore environments and significantly improved the efficiency of the reclamation operation.

River Desilting Project

Project Background

The project involved river desilting and waterway maintenance in an urban area. Small cutter suction dredgers were used to remove accumulated sludge and sediment. Flexible dredging hoses were required due to the complex pipeline layout and limited working space.

Product Details

• Product: Suction & Discharge Dredging Hose

• Size: DN300

• Features: High flexibility, vacuum resistance, abrasion resistance

• Connection Type: Quick flange connection

Project Advantages

• Flexible pipeline installation

• Reduced vibration and operational impact

• Improved construction efficiency

• Shorter installation and maintenance time

Customer Feedback

The dredging hoses showed excellent flexibility and durability, helping the contractor complete the desilting work efficiently and safely.

Mining Slurry Transfer Project

Project Background

This mining project required the transportation of tailings slurry containing high-abrasion solid particles. The customer needed a heavy-duty slurry hose solution with outstanding wear resistance and long operational life.

Product Details

• Product: Heavy Duty Slurry Hose

• Size: DN450

• Inner Layer Material: High abrasion-resistant natural rubber

• Reinforcement: Steel wire spiral reinforcement

• Working Pressure: 20 bar

Project Advantages

• Extended service life under abrasive conditions

• Reduced hose replacement frequency

• Lower maintenance downtime

• Improved slurry transportation efficiency

Customer Feedback

The heavy-duty slurry hoses significantly reduced maintenance costs and delivered reliable performance under continuous mining operations.
