Large Diameter Flexible Flanged Rubber Hose

JIDONGDA Large Diameter Flexible Flanged Rubber Hose is mainly used for flexible connection and media transportation between large equipment, pump units, pipelines and mobile equipment.

The product adopts a rubber hose body combined with reinforcement structures and is equipped with flanges at both ends. It is suitable for conveying:

· Water

· Seawater

· Slurry

· Mineral slurry

· Sand and gravel

· Tailings

· Some industrial media

The main positioning of this product is flexible connection. Therefore, during selection, besides pressure and diameter, factors such as equipment vibration, pipeline displacement, installation deviation, bending space and hose length should also be considered.

Key Advantages

01 | Flexible Connection Capability

The rubber hose body provides certain bending and displacement adaptability, making it suitable for flexible connections near equipment interfaces.

02 | Large Flow Conveying

The large diameter structure can be used for large-volume media transportation. The specific diameter range shall be confirmed according to the actual product and project requirements.

03 | Flange Matching

Both ends can be equipped with carbon steel, stainless steel or other flanges, and can be matched according to common standards or customer drawings.

04 | Optional Suction and Discharge Structure

According to actual vacuum requirements, suitable reinforcement structures and spiral steel wire frameworks can be configured.

05 | Medium Adaptability

For media such as water, seawater, slurry, mineral slurry and sand, suitable inner rubber materials can be selected according to material requirements and wear conditions.

06 | Non-standard Customization

Customization is available for:

· Diameter

· Length

· Pressure

· Vacuum pressure

· Temperature

· Flange

· Rubber compound

· Color

Product Structure

The inner rubber layer directly contacts the conveying medium.

The reinforced fabric layer bears the pressure load.

When vacuum support is required, a spiral steel wire reinforcement structure can be configured.

The outer rubber layer provides aging resistance and environmental protection.

The end flanges are used for bolted connections between equipment and pipelines.

Why Choose Flexible Flanged Structure

When fixed pipelines experience pump unit vibration, equipment movement or installation errors, additional stress may occur at connection points.

Flexible rubber hoses can serve as flexible sections in pipelines, helping accommodate certain displacement and vibration.

The actual allowable bending radius, displacement range and installation method should be confirmed according to the specific structure.

Typical Installation Locations

Commonly used at:

· Pump suction or discharge ends

· Connections between equipment and main pipelines

· Mobile equipment connection points

· Industrial pipelines requiring frequent installation and disassembly

The flange dimensions must match the mating flange, sealing surface and bolt hole positions.
