Conventional delivery hoses often suffer from poor abrasion resistance — they wear through quickly under sand and gravel particle scouring. Additional issues include insufficient pressure capacity for high-volume flow, limited throughput due to smaller diameters, and cracking at low temperatures or aging at high temperatures. Frequent replacements add engineering costs and downtime losses.
Manufactured by Hengshui Zhehan Rubber & Plastic, the abrasion-resistant large-diameter sediment and particle delivery hose combines a highly abrasion-resistant rubber lining with a multi-layer steel wire reinforcement structure. It is engineered specifically to handle the high-intensity wear and impact of sediment, pebbles, and mine slag particles, delivering stable pressure performance, controlled deformation, and reliable operation across varying temperature conditions.
For custom diameter, pressure, and length specifications matched to your project conditions, contact us for a tailored abrasion-resistant large-diameter sediment and particle delivery hose selection guide and quotation.
We focus on solving the industry-wide challenges of hose wear, blowout, leakage, and short service life in high-volume sediment and particle transfer applications. Leveraging mature rubber-plastic molding processes, we deliver highly adaptable industrial delivery hose solutions.
Customizable parameter specifications match individual project conditions, ensuring the abrasion-resistant large-diameter sediment and particle delivery hose performs reliably under continuous high-intensity operation and substantially reduces equipment maintenance frequency and replacement costs.
With high abrasion resistance, high pressure capacity, and broad adaptability, we provide long-lasting, safe, and efficient particle media transfer solutions for customers in dredging, mining, and infrastructure sectors.
River and Lake Dredging: Compatible with cutter suction dredgers and desilting vessels for suction and discharge of silt, sand, and mixed particle slurry in rivers, lakes, and reservoirs. The large-diameter design supports high-volume desilting throughput with excellent resistance to water flow impact and sediment abrasion.
Mine Tailings Transport: Handles mine slurry, tailings slag, and crushed stone particle mixtures. Tolerates frictional scouring from sharp ore particles and supports continuous mine transfer operations, effectively avoiding the rapid wear failure common with standard hoses.
Port and Marine Sand Extraction: Suited for sand suction and discharge on offshore and riverside dredging vessels. Resists seawater corrosion and high-intensity sand abrasion. Its flexible construction accommodates vessel motion and pipeline bending in complex offshore operating conditions.
Infrastructure Slurry Delivery: Widely used on road, bridge, and tunnel construction sites for slurry, muck, and sand-gravel mixture transfer. Stable performance across temperature ranges, suited for outdoor open-air construction environments, with straightforward installation and strong compatibility.
The lining uses a specially formulated high-abrasion rubber compound with abrasion resistance 4 to 7 times that of ordinary rubber hose. It withstands sustained scouring from hard particles such as sediment, pebbles, and mine slag, extending the service life of the abrasion-resistant large-diameter sediment and particle delivery hose by more than 60% and significantly reducing replacement frequency.
Custom large-diameter sizes from DN200 to DN1000 are available. The smooth inner bore provides unobstructed flow with full cross-section capacity and no diameter reduction or clogging issues. Per-hour delivery throughput increases by approximately 30% compared to standard hoses, making it well suited for high-volume sediment transfer projects.
A multi-layer steel wire winding plus fabric composite reinforcement structure, vulcanized as a single unit, delivers compact pressure resistance. Standard working pressure ranges from 1.0 to 4.0 MPa, with burst pressure rated at three times the working pressure or higher. Under high-pressure conditions, the hose resists bulging, blowout, and leakage.
A specialized rubber-plastic material formulation supports operation across a -20°C to 50°C temperature range. It resists seawater and weak acid/alkali slurry corrosion, as well as UV and aging degradation. Long-term stable performance is maintained in open-air, submerged, and humid operating environments.
Excellent flexibility allows bending to accommodate complex pipeline layouts. Repeated bending during operation does not cause delamination or cracking. Integrally formed flange connections simplify installation and connection, suitable for both mobile equipment and fixed pipeline installations.

During installation, match flanges and fasteners to the correct specifications to ensure a tight, sealed connection. Never operate the abrasion-resistant large-diameter sediment and particle delivery hose beyond rated pressure or temperature limits. During operation, prevent sharp objects from cutting or crushing the hose body, as localized damage can lead to leakage or blowout.
Before resuming use after extended shutdown, inspect the hose body for cracking, delamination, and aging signs. When conveying high-hardness particle media, reducing instantaneous flow velocity can lower scouring wear. For storage, keep the hose in a dry, well-ventilated area away from direct sun, rain, and compressive deformation to maximize service life.
This hose must not be used for strong acid, strong alkali, or other highly corrosive media transfer. For operating conditions beyond rated temperature and pressure limits, contact the factory in advance for a custom-adapted product. When bending the hose in service, avoid sharp kinks that could break internal steel wires and cause delamination failure.
Q: What are the minimum order requirements?
A: Standard stocked specifications are available for small-batch orders. Custom specification minimums are flexible and produced to match project requirements, with no rigid large-quantity restrictions.
Q: What customization options do you offer?
A: We support full-dimensional customization including size, pressure rating, wall thickness, flange style, and logo printing. Production can be tailored to your equipment conditions and drawing specifications.
Q: How long is the warranty period?
A: Our abrasion-resistant large-diameter sediment and particle delivery hoses are manufactured to industry standards and fully inspected before shipment. The warranty period is 12 months, with free after-sales service for non-human-caused quality issues.
Q: Do you supply the hoses with flanges pre-installed?
A: Yes. We can supply the hose with integrally vulcanized flanges of your specified type and rating, ready for direct bolt-on installation. Specify your flange standard (e.g., PN, ANSI, DIN) when requesting a quotation.
Q: Can this hose be used for both suction (negative pressure) and discharge?
A: Standard configurations are designed primarily for positive-pressure discharge. For suction or vacuum dredging applications, we recommend our dedicated suction dredge hose variant with additional structural reinforcement. Contact our technical team to specify the right model.
Q: What is the typical lead time for custom large-diameter orders?
A: Custom large-diameter orders typically require 15 to 25 working days depending on diameter size, length, and order volume. Stocked standard sizes can ship within 3 to 5 working days. We confirm a specific delivery schedule with each order.
