Large Diameter Fabric Reinforced Flanged Rubber Hose

JIDONGDA Large Diameter Fabric Reinforced Flanged Rubber Hose is a dual-purpose suction and discharge hose specifically designed for heavy industry and marine engineering. Unlike ordinary rubber hoses, it uses a composite reinforcement process of fabric cord and steel wire spiral, completely solving industry pain points such as negative pressure collapse, hose wear, poor flexibility, and short service life of traditional hoses.

The product supports diverse customization options for pipe diameter, length, pressure rating, and flange standards, and is compatible with mainstream international standards such as ANSI, DIN, JIS, and BS. It is adaptable to complex working conditions such as high negative pressure operations, abrasive erosion, seawater corrosion, and outdoor aging, making it a core supporting equipment for large-scale dredging, mining, and marine fluid engineering projects.

Core Advantages

1. Superior Wear Resistance

The inner layer of the pipe uses a customized composite wear-resistant formula of natural and synthetic rubber, which can withstand the erosion of media such as sand and slurry for extended periods, significantly reducing the pipe's wear rate and effectively extending the equipment's service life.

2. Excellent Negative Pressure Resistance

The built-in integrated steel wire spiral support structure provides stable support for the pipe, preventing hose collapse, deformation, and blockage during negative pressure suction operations, ensuring continuous and stable media delivery.

3. Excellent Flexibility and Easy Installation

The multi-layered fabric cord reinforcement structure gives the hose excellent bending performance, allowing for installation in complex terrains and narrow working conditions, significantly reducing construction difficulty and improving installation efficiency.

4. Corrosion and Erosion Resistance

The specialized rubber formula is resistant to corrosion from seawater, industrial wastewater, and trace amounts of chemical fluids. It exhibits excellent stability and is resistant to cracking and peeling during long-term operation in marine and chemical environments.

5. Weather and Ozone Resistance

The outer layer of the Large Diameter Fabric Reinforced Flanged Rubber Hose is made of weather-resistant and ozone-resistant synthetic rubber, resisting outdoor ultraviolet radiation, marine salt spray, and ozone corrosion. It maintains stable physical properties even during long-term outdoor and marine operations.

6. Customization for All Scenarios

Supports personalized customization of pipe diameter, pipe length, working pressure, flange type, and rubber formula, precisely matching the differentiated usage requirements of various engineering projects and equipment.

Product Structure:

1. Inner Rubber Layer: Utilizes high-quality wear-resistant natural rubber, styrene-butadiene rubber, or customized special rubber compounds, emphasizing wear and corrosion resistance, suitable for conveying various abrasive and corrosive media.

2. Reinforcing Layer: Composed of multiple layers of high-strength synthetic fabric cords reinforced with a steel wire spiral, this layer balances flexibility, pressure resistance, and negative pressure resistance, comprehensively enhancing the overall structural strength of the hose.

3. Outer Rubber Layer: Utilizing high-performance weather-resistant, ozone-resistant, and wear-resistant synthetic rubber, this layer provides comprehensive protection for the internal reinforcing structure, preventing damage from the external environment and extending the hose's service life.

4. Flange Connection: Available with carbon steel, galvanized steel, or stainless steel flanges, compatible with ANSI, DIN, JIS, BS, and custom flange standards. The connection is secure, with excellent sealing, ensuring leak-free operation under high pressure.

Stringent Performance Testing System

1. Water Pressure Test: Full pressure testing ensures the working pressure meets standards, mitigating the risk of pipe bursts and leaks;

2. Negative Pressure Test: Simulates extreme negative pressure conditions to verify the hose's resistance to collapse and stable suction performance;

3. Burst Pressure Test: Ensures the product's burst pressure is far higher than the industry safety threshold;

4. Adhesion Test: Tests the bonding strength between the rubber layer and the reinforcing layer to prevent delamination and pipe failure;

5. Abrasion Resistance Test: Assesses the hose's service life under long-term transport of abrasive media;

6. Dimensional and Appearance Inspection: Precisely verifies dimensional tolerances and identifies surface defects and manufacturing flaws.

Real-World Engineering Application Case

Case Study: Yangtze River Channel Dredging Project

Large-scale dredging projects in the middle and lower reaches of the Yangtze River require long-term transport of high-concentration silt and gravel mixtures. Traditional ordinary hoses are prone to negative pressure collapse and severe wear, with a service life of only 12 months. This project utilizes JIDONGDA DN500 Large Diameter Fabric Reinforced Flanged Rubber Hose. Relying on its steel wire reinforcement structure and highly wear-resistant inner rubber layer, it has operated continuously for 1200 hours without deformation, collapse, or wear issues, extending its service life to 36 months. Annual equipment replacement and maintenance costs are reduced by over 65%, ensuring efficient waterway dredging.

Wide Application Scenarios

1. Dredging Industry: Cutter suction dredgers, trailing suction hopper dredgers, river and port dredging, land reclamation projects;

2. Mining Industry: Slurry transportation, tailings transport, fluid transportation in mineral processing plants;

3. Marine Engineering: Offshore construction, coastal protection, artificial island construction, seawater intake systems;

4. Industrial Sector: Industrial fluid transportation, media transportation in wastewater treatment plants;

5. Sand and Gravel Industry: Sand and gravel mining, aggregate transportation, quarry waste transportation.

FAQ

Q1: What is the core difference between JIDONGDA fabric-reinforced flanged hoses and ordinary steel wire hoses?

A1: This product uses a composite reinforcement structure of "high-strength fabric cord + steel wire spiral," which, compared to ordinary single-wire flexible hoses, offers stronger bending toughness and resistance to deformation. It is less prone to damage from repeated bending and provides more even pressure distribution.

Q2: Does the Large Diameter Fabric Reinforced Flanged Rubber Hose support special flange standards and non-standard pressure customization?

A2: Yes. JIDONGDA offers full-dimensional personalized customization services, adaptable to mainstream international flange standards such as ANSI, DIN, JIS, and BS. Non-standard flanges, pipe diameters, pipe lengths, and working pressures can also be customized according to working conditions.

Q3: What about product quality and after-sales service?

A3: All JIDONGDA products are manufactured strictly according to international quality standards. From raw material warehousing to finished product delivery, the entire process undergoes quality inspection, and each batch of products comes with a complete test report.
