Large Diameter Heavy-Duty Flanged Rubber Hose

JIDONGDA Large Diameter Heavy-Duty Flanged Rubber Hose is designed for more demanding engineering environments compared with ordinary conveying hoses.

Media such as mineral slurry, sand, gravel and tailings can cause continuous wear on the inner wall of the hose. Meanwhile, large equipment operation may also involve vibration, pressure fluctuations and mechanical loads.

Therefore, the selection of this product should not focus on a single parameter, but should consider the overall matching of:

· Inner rubber wear resistance

· Reinforcement layer

· Outer rubber protection

· Flange connection

· Actual operating conditions

Heavy-Duty Selection Logic

Heavy-duty hoses do not simply mean increasing the wall thickness.

What needs to be confirmed is the medium wear level, working pressure, vacuum pressure, length, bending condition, installation environment and flange stress conditions.

For highly abrasive slurry applications, the particle size and concentration of the medium should be provided as a priority.

Structure and Wear-Resistant Design

The inner rubber layer is responsible for medium contact and wear resistance.

Multiple layers of cord fabric/fabric reinforcement form the main reinforcement structure.

According to suction conditions, spiral steel wire can be added.

The outer rubber layer provides environmental protection.

The flange serves as the end connection structure.

Media containing particles such as sand, mineral slurry and tailings will continuously wash and wear the inner wall.

The inner rubber material and structure should be selected according to actual wear conditions.

The existing information does not specify a unified wear-resistant rubber compound, so the final order should be confirmed according to specific operating conditions.

Technical Parameters and Quality Control

Diameter, length, working pressure, working vacuum pressure and temperature need to be confirmed according to the structure.

According to order requirements, inspections can be carried out for:

· Appearance

· Dimensions

· Flange

· Pressure

· Vacuum / Negative Pressure

· Hardness

· Rubber Performance

Special testing standards should be agreed in advance.

Application Industries

Mining:
Mineral slurry, tailings and ore slurry.

Flange Configuration

Flanges can be confirmed according to:

· GB

· DIN

· ANSI

· JIS

· ASME

· Customer drawings

During purchasing, the following flange details should be checked:

· Flange outer diameter

· Number of bolt holes

· Bolt hole diameter

· Bolt hole spacing

· Thickness

· Sealing surface

· Connection dimensions

Maintenance Focus

Under heavy-duty operating conditions, regular inspection records should be established.

Attention should be paid to:

· Inner and outer rubber wear

· Bulging

· Cracks

· Flange loosening

· Leakage

If the actual pressure, vacuum pressure or conveying medium changes, the product suitability should be re-evaluated.

FAQ

What situations are heavy-duty hoses recommended for?

When the conveying medium has strong abrasion, the equipment load is high, or the project requires higher structural reliability, a heavy-duty configuration can be considered.

Can it be used for tailings transportation?

Yes. The wear-resistant structure can be confirmed according to the particle size, concentration, pressure and flow rate of the tailings.

Are heavy-duty hoses always rated for higher pressure than ordinary hoses?

Heavy-duty does not necessarily mean a higher pressure rating. The final working pressure should be determined according to the specific structure and technical parameters.

Can customer drawings be supported?

Yes. The flange and product structure can be confirmed according to customer drawings.

Can it be used for project bulk orders？

Yes. Specifications, quantity, inspection requirements and delivery time can be determined together during the project technical confirmation stage.
