Large Diameter Mortar Slurry Hose

JIDONGDA Large Diameter Mortar Slurry Hose is a heavy-duty flexible rubber pipe designed for high-particle abrasion and high-solids-content applications. The inner lining uses a composite high-wear-resistant rubber formula, combined with multiple high-strength reinforcement layers, and an optional spiral steel wire skeleton, enabling continuous and stable material delivery in complex media such as mud, mortar, slag, and construction grout.

In high-wear conveying scenarios, it is an efficient alternative to steel pipes: steel pipes are prone to wear and breakage, pipeline layout is limited, and frequent downtime for maintenance; while JIDONGDA hoses combine wear resistance, flexibility, and pressure resistance, enabling long-term cost reduction for engineering and mining customers.

Structural Design and Material Configuration

The Large Diameter Mortar Slurry Hose features a structure optimized for wear resistance and structural stability in each layer, with customizable specifications based on the conveying medium:

1. Inner Liner: High-wear-resistant natural rubber (NR) + synthetic wear-resistant rubber composite formula, resisting continuous erosion from solid particles.

2. Reinforcing Layer: Multi-layer high-strength fiber winding; spiral steel wire skeleton optional for high-pressure conditions.

3. Buffer Layer: Impact-resistant transition layer, buffering the instantaneous impact of large solid particles.

4. Outer Protective Layer: Cut-resistant, wear-resistant, and UV-resistant rubber outer skin, suitable for long-term outdoor use.

5. End Connectors: Standard flanges and clamp connectors; quick-connect couplings can be customized for convenient on-site assembly.

Performance Testing and Quality Verification

1. Wear Resistance Test: Simulating high-speed circulation erosion of mineral slurry containing sand, the inner lining wear rate is far lower than the industry standard, and the service life is more than twice that of ordinary slurry hoses.

2. Pressure Testing: Working pressure 0.6–1.6 MPa, burst pressure ≥ 3 times the working pressure; alternating water pressure and slurry pressure testing is used to eliminate potential leakage risks.

3. Impact Resistance Testing: Simulating continuous impact of large aggregates, cyclic impact ≥ 10,000 times; no cracking, bulging, or structural damage after testing.

4. Bending Fatigue Testing: Repeated bending of the entire large-diameter pipe to test flexibility and interlayer adhesion strength; no delamination, slurry leakage, or permanent deformation issues.

Real-World Engineering Application Cases:

Case 1: Inner Mongolia Iron Mine Tailings Transportation Project

The original seamless steel pipes transporting iron ore tailings wore through within 2-3 months due to high-hardness mineral particles, resulting in frequent shutdowns and high replacement costs.

1. Solution: DN400 JIDONGDA flexible hoses with steel wire reinforcement were selected, lined with custom-made ultra-wear-resistant rubber material suitable for high-density iron tailings.

2. Performance Results: After 16 months of continuous operation, only slight, uniform wear was observed, with no perforations. Maintenance downtime frequency was reduced by 75%, saving over 100,000 RMB annually in replacement and maintenance costs.

Case Study 2: Southeast Asian Port Estuary Dredging and Reclamation Project

Dredging vessels need to transport mixed coral gravel and silt over long distances. Offshore conditions require floating pipelines, and ordinary thin-walled hoses are easily damaged by particle impact.

1. Solution: Supply of DN600 dredging hoses with a full UV-resistant outer layer, flanged fittings, and steel frame packaging, suitable for sea transport.

2. Performance Results: Stable operation throughout the entire 8-month construction period, adaptable to tidal floating and bending without leakage, and construction efficiency improved by 28% compared to traditional rigid pipelines.

FAQ

Q1. Which pressure rating of JIDONGDA Large Diameter Mortar Slurry Hose should be selected for tailings transportation in mines?

A: For standard low to medium solids tailings, a 0.6–1.0MPa hose without a steel wire skeleton is recommended; for high-density coarse particles and conditions with large pressure fluctuations, a 1.0–1.6MPa model with spiral steel wire reinforcement is recommended, providing a burst safety factor of 3 times to prevent tearing due to sudden pressure changes. Our technical team can provide customized selection solutions based on slurry concentration and pump parameters.

Q2. Can this Large Diameter Mortar Slurry Hose completely replace steel pipes for long-distance fixed pipelines?

A: For elbows, pump body interfaces, and areas with severe erosion and wear, steel pipes can be completely replaced. For long-distance straight main pipes, steel pipes are recommended as the primary material, with JIDONGDA flexible hoses used in easily worn sections. The hoses buffer pipeline vibration and particle impact, reducing overall pipeline wear and minimizing maintenance frequency.

Q3. For overseas engineering orders, can JIDONGDA customize pipe diameters, lengths, and end fittings?

A: Yes. As a professional manufacturer, we support full OEM/ODM customization. Inner diameters can be made from DN100 to DN1000, and single-piece lengths can be customized. Flanges, clamps, and special quick-connect fittings can all be fabricated according to drawings. For special media such as chemical sludge, coral sand, and high-silica slurry, the wear-resistant lining formula can be adjusted. Export orders come with a complete set of quality inspection reports.
