Large Diameter Water Discharge Hose

The Large Diameter Water Discharge Hose is a professional, flexible industrial hose designed for transporting large volumes of fluid and for rapid drainage operations. Constructed from high-quality synthetic rubber with a multi-layer reinforcement structure, it maintains its integrity and high drainage efficiency during prolonged continuous use, high-pressure operation, and demanding outdoor conditions.

Unlike traditional rigid piping, the JIDONGDA Large Diameter Water Discharge Hose features a flexible design that facilitates easy routing and installation. This significantly simplifies construction work, shortens project timelines, and reduces overall engineering costs. Leveraging proven manufacturing technologies and a comprehensive quality control system, we—as a professional manufacturer—offer custom-made large-diameter drainage hoses for water management and fluid transport projects worldwide.

Product Construction

1. Inner rubber layer

Made from hydrolysis- and abrasion-resistant synthetic rubber, this layer offers excellent compatibility with the conveyed media. It withstands high-velocity flows and exposure to wastewater, recycled water, and agricultural water, preventing damage to the inner walls and pipeline clogging.

2. Reinforcing carcass layer

A multi-layer structure composed of high-strength polyester cord. This significantly enhances tensile strength and burst resistance, enabling the hose to withstand sudden pressure surges during high-intensity fluid flow without expanding or cracking.

3. Stabilizing load-bearing layer

Features a special design that optimizes load distribution along the entire length of the hose. This effectively minimizes deformation, sagging, and flattening—issues that can arise during prolonged use or under constant loads—thereby maintaining a stable diameter and ensuring unobstructed fluid flow.

4. Outer protective layer

Made from a weather-resistant rubber compound that effectively withstands UV radiation, ozone aging, moisture-induced corrosion, and mechanical abrasion. The material is designed for long-term outdoor use and the harsh conditions of construction sites, significantly extending the product's service life.

Key Product Features

1. High flow capacity: A specialized large-diameter design ensures high flow rates, enabling rapid drainage of accumulated water and enhancing efficiency for both emergency drainage and standard water transfer operations.

2. Lightweight and portable: The product is lighter than metal or rigid pipes of similar specifications; it can be coiled or folded, saving space during transport and reducing labor requirements for handling and installation.

3. Excellent flexibility: The highly flexible body allows for routing across challenging terrain (uneven surfaces, slopes, obstacles) and navigating bends without creating flow stagnation zones.

4. Superior weather resistance: Reliable performance in high temperatures, rain, high humidity, and intense UV radiation, making the hose suitable for year-round outdoor use.

5. Easy connection: Compatible with quick-connect couplings and standard flanges; simple installation and removal—without the need for complex equipment—ensure high operational efficiency on-site.

6. Long service life: A combination of high-quality materials and a multi-layer reinforced structure provides resistance to aging, abrasion, and deformation, ensuring stable long-term performance and reducing the frequency of equipment replacement.

Real-world Project Example

1. Project Name: Flood Protection and Drainage System Upgrade Project (Jiangxi Province, China, 2025).

2. Project Background: Many low-lying urban areas in Jiangxi Province are prone to flooding on roads and in residential complexes during heavy rains in the flood season, severely disrupting transportation and resident mobility. Existing rigid piping systems had limited capacity and failed to provide an effective emergency response, unable to cope with sudden downpours and water accumulation.

3. Project Plan: This Large Diameter Water Discharge Hose utilizes JIDONGDA DN1200 large-diameter water delivery hoses, combined with quick-connect flanges and custom-made, ultra-long 800-meter hose sections. The solution addresses key challenges such as preventing water accumulation on major urban roads, draining underground garages, and managing river water levels.

4. Results: The hoses were deployed within two hours of the onset of rain; a single hose achieved a flow capacity of 1,200 m³/h, effectively resolving urban flooding issues. Compared to traditional temporary steel piping, installation time was reduced by 60%, and the total project cost decreased by 35%. After more than six months of operation, the hoses showed no signs of aging, deformation, or leakage; they reliably withstood numerous heavy rainstorms, successfully upgrading the urban drainage system.

Frequently Asked Questions

Q1: What are the pressure and temperature ranges for JIDONGDA Large Diameter Water Discharge Hoses?

A1: Standard hoses are rated for a working pressure range of 0.3–1.6 MPa, while specialized high-pressure models can withstand up to 2.5 MPa. The operating temperature range is -20°C to 60°C, meeting the requirements of most applications—whether outdoors or in standard industrial environments. Options with specialized rubber compounds are available for use in extremely high or low temperatures.

Q2: Can this large-diameter drainage hose be reused?

A2: Yes. JIDONGDA large-diameter drainage hoses feature a multi-layer reinforced construction that is resistant to aging, wear, and deformation. With proper use, cleaning, and maintenance, they can be coiled for storage and reused; they resist damage from water flow or bending during installation, significantly reducing equipment replacement costs.

Q3: Which international standards do the hose fittings meet?

A3: Associated components—such as flanges and connectors—fully comply with major international standards, including ANSI, DIN, and JIS. They are also compatible with standard quick-connect systems, ensuring seamless integration with common domestic and international drainage equipment, as well as high versatility and ease of installation.
