Large-bore high-pressure flexible hoses are specifically designed pipeline components for conveying high-pressure fluids. Below is a detailed introduction to them:

I. Structural Features

Large diameter high-pressure hoses are typically composed of an inner rubber layer, a reinforcing layer, and an outer rubber layer. The inner rubber layer is responsible for contacting and sealing the fluid, the reinforcing layer provides the necessary strength and pressure-bearing capacity, and the outer rubber layer serves as a protective layer, preventing the hose from being damaged by external environments. Additionally, depending on specific requirements, the hose may also include other special layers, such as wear-resistant layers and corrosion-resistant layers.

Section 2: Material Selection

1. ‌Internal rubber layer materialSelect materials with high sealing properties and resistance to fluid corrosion, such as NBR (nitrile rubber), EPDM (ethylene propylene diene monomer), or fluoro rubber, etc.

2. ‌Enhanced layer materialTypically made of high-tensile steel wire braided or wrapped, to ensure the hose does not burst or deform under high pressure.

3. ‌Outer rubber layer materialSelect materials with abrasion, weather, and corrosion resistance, such as chloroprene rubber, polyurethane, or PVC, etc.

Section 3: Performance Advantages

1. ‌High-pressure bearing capacityLarge-bore high-pressure flexible hoses can withstand pressure to ensure stable transmission of fluids within the pipeline.

2. ‌Excellent sealing propertiesThe selection of the inner rubber layer material and the structural design ensure that the hose maintains excellent sealing performance under high pressure.

3. ‌Fluid-resistantThe inner layer material can withstand corrosion from various chemicals, extending the lifespan of the hose.

4. ‌Wear and weather resistanceThe choice of the outer rubber layer material ensures that the hose maintains stable performance in harsh working conditions.

Section 4: Application Fields

Large-bore high-pressure hoses are widely used in the oil, chemical, metallurgy, shipbuilding, and other fields, particularly in situations requiring the conveyance of high-pressure fluids, corrosive media, or high-temperature media.
