High Abrasion Resistance Dredging Hose With Steel Armor And Long Service Life
Description
The Armored Hose is a heavy-duty flexible hose designed for high-load and high-abrasion marine operations. It features a multi-layer rubber construction reinforced with integrated steel armor, providing exceptional resistance to mechanical impact, external compression, and internal wear. Manufactured using premium synthetic rubber compounds and high-tensile steel rings or chains, this hose maintains structural stability under extreme working conditions.
With a large inner diameter range and customized length options, the hose is suitable for continuous material transfer where durability and reliability are critical. Its excellent abrasion resistance significantly reduces wear caused by solid particles, while the reinforced structure enhances load-bearing capacity and service life. The Armored Hose delivers consistent performance in demanding marine environments, offering long-term operational value and reduced replacement frequency.
Case Study
During a major port expansion project, a dredging contractor operating a 12,000 DWT cutter suction dredger faced frequent hose failures due to severe abrasion and external impact from rocky seabed materials. Standard rubber hoses required replacement every few months, causing downtime and high maintenance costs.
Hongruntong Marine supplied customized Armored Hoses with enhanced steel armor density and thicker wear-resistant inner lining. After installation, the hose system operated continuously for over 18 months without structural damage. The client reported a 40% reduction in maintenance costs and significantly improved operational safety. Based on the results, the same hose configuration was replicated across additional vessels in the fleet.

Key Features
High Abrasion Resistant Inner Lining
The inner tube is made from specially formulated rubber compounds designed to withstand continuous friction from sand, gravel, and slurry. This reduces material loss and extends service intervals even under high flow velocity conditions.
Integrated Steel Armor Reinforcement
The external steel armor provides superior resistance against crushing, impact, and bending stress. This structure protects the hose from mechanical damage while maintaining flexibility during operation.
High Load-Bearing Capacity
Designed to handle heavy materials and external loads, the hose maintains dimensional stability under pressure and weight, making it suitable for demanding marine operations.
Long Service Life Design
Optimized material selection and reinforced construction significantly reduce fatigue and wear, resulting in a longer operational lifespan and lower total cost of ownership.
Applications
Dredging and Slurry Transfer Systems
Ideal for transferring abrasive mixtures with high solid content where conventional hoses fail prematurely.
