This type of pipeline is a critical component in dredging projects (such as riverbed cleaning, port expansion, sand suction and filling, etc.). It is connected to equipment or other pipe sections via live flanges (i.e., removable flanges).

Advantages of Live Flange Dredging Rubber Hoses:

1. Extremely high flexibility and resistance to bending

◦ Advantages: The rubber hose itself is very flexible, able to adapt to complex working terrains such as curved rivers and undulating seabeds. It can bend along with the movement of the working vessel, unlike steel pipes which are prone to jamming or require numerous bends.

◦ Value: Significantly improves operational flexibility and efficiency, reducing the difficulty and time of pipeline layout.

2. Excellent wear resistance and corrosion resistance

◦ Advantages: Specialized dredging rubber hoses have an inner lining of highly wear-resistant rubber (such as natural rubber, wear-resistant composite rubber), which effectively resists erosion from solid particles like mud, gravel, and slag. Additionally, rubber exhibits good corrosion resistance to seawater, freshwater, and most chemicals, unlike steel pipes which are prone to rusting.

◦ Value: Long service life, particularly suitable for conveying abrasive media containing sharp particles, reducing long-term operational replacement costs.

3. Superior impact and tensile strength

◦ Advantages: The hose body is typically reinforced with multiple layers of high-strength synthetic fiber cord or steel wire winding, enabling it to withstand high internal pressure and external tensile forces. The elasticity of rubber can absorb energy from material impacts and water hammer effects, preventing pipe rupture.

◦ Value: Ensures safety and reliability under harsh operating conditions, capable of withstanding sudden load changes and towing forces.

4. Lightweight, easy to handle and install

◦ Advantages: Compared to steel pipes of the same diameter and length, rubber hoses are much lighter. Combined with the live flange design, individual pipe sections are very convenient to disassemble, handle, and install, usually without the need for large lifting equipment.

◦ Value: Significantly reduces labor intensity and installation/dismantling time, accelerating project progress, especially suitable for projects requiring frequent relocation.

5. Good sealing performance and convenient connection

◦ Advantages: Live flange connections typically use gaskets or packing to provide reliable sealing, preventing leaks. The flange plates are removable, allowing quick and firm connect between pipes.

◦ Value: High connection efficiency, good sealing effect, reducing environmental pollution and energy loss caused by medium leakage.

6. Vibration damping and noise reduction

◦ Advantages: The rubber material effectively absorbs vibrations and noise generated by the pumping system, making the entire dredging system operate more smoothly.

◦ Value: Enhances equipment lifespan and improves working conditions.
