JIDONGDA Wire Reinforced Large Diameter Flanged Rubber Hose is a heavy-duty flexible hose solution developed for the transportation of water, slurry, mud, sand, mineral materials, and other compatible media in large-scale pipeline systems.

Compared with conventional large-diameter rubber hoses, this product integrates a spiral steel wire reinforcement structure into the hose wall to improve structural stability during suction operations. When the hose works under negative pressure, external atmospheric pressure may cause the hose body to deform inward. The embedded steel wire skeleton helps maintain the original hose shape and supports stable material flow.

The hose is suitable for connection between pumps, dredging equipment, pipeline systems, and other industrial equipment. With customizable diameter, length, reinforcement structure, and flange configuration, JIDONGDA provides flexible solutions for different engineering requirements.

Product Structure

JIDONGDA Wire Reinforced Large Diameter Flanged Rubber Hose adopts a multi-layer composite structure designed for demanding suction and discharge applications.

Inner Rubber Layer

The inner layer directly contacts the transported medium. Different rubber compounds can be selected according to the characteristics of slurry, sand, mineral particles, water, and other materials to improve wear resistance and service reliability.

Reinforcement Layers

Multiple layers of high-strength fabric or reinforcement materials provide pressure resistance and structural strength, allowing the hose to withstand internal pressure during discharge operations.

Spiral Steel Wire Reinforcement Layer

The spiral steel wire embedded in the hose wall forms a continuous support structure around the hose circumference. It improves resistance against vacuum deformation and helps maintain the hose cross-section during suction operations.

Outer Rubber Layer

The outer cover protects the hose against external wear, impact, weather conditions, and mechanical damage during transportation and installation.

Flanged Ends

Both ends can be equipped with flange connections according to pipeline requirements, enabling connection with pumps, dredging equipment, and fixed pipeline systems.

Working Function of Spiral Steel Wire Reinforcement

During suction or vacuum operation, large-diameter hoses are exposed to external atmospheric pressure. Without sufficient structural support, the hose body may experience inward deformation, resulting in reduced flow efficiency or even hose collapse.

The spiral steel wire in JIDONGDA Wire Reinforced Large Diameter Flanged Rubber Hose acts as a supporting framework inside the hose wall. It provides circumferential reinforcement, improves shape retention, and helps the hose maintain stable operation under negative pressure conditions.

The actual vacuum resistance depends on multiple factors, including steel wire specifications, wire spacing, hose diameter, reinforcement layers, hose length, bending conditions, and operating environment. JIDONGDA can optimize the hose structure according to specific project requirements.

Product Advantages

01｜Spiral Steel Wire Support for Negative Pressure Stability

JIDONGDA Wire Reinforced Large Diameter Flanged Rubber Hose uses a spiral steel wire reinforcement structure to provide continuous circumferential support. It helps reduce hose flattening and collapse risks during vacuum suction operations, improving stability in large-diameter suction pipelines.

02｜Suitable for Both Pressure and Vacuum Conditions

The hose structure is designed to consider both positive pressure discharge and negative pressure suction requirements. Reinforcement layers handle internal pressure, while the spiral steel wire improves resistance against external pressure during vacuum operation.

03｜Large Diameter for High-Volume Transportation

The large-bore design supports efficient transfer of high-volume media, making it suitable for dredging, mining, and industrial systems requiring continuous material flow.

04｜Reliable Flange Connection

With customizable flange standards and dimensions, JIDONGDA Wire Reinforced Large Diameter Flanged Rubber Hose can be integrated with pumps, dredgers, and pipeline systems for convenient installation and reliable connection.

05｜Customized Material Selection for Different Media

According to different working media and abrasion conditions, suitable inner rubber materials can be selected to improve wear resistance and extend service performance.

06｜Engineering-Based Customization

JIDONGDA supports customized solutions covering hose diameter, steel wire structure, reinforcement layers, length, flange design, and material selection to meet different project requirements.
