Sleeves of a high pressure (HPR)

High pressure hoses (HHP)

A high-pressure hose (HHP) is a flexible pipeline designed for transporting working fluids under high pressure in hydraulic systems. The design of a high-pressure hose includes several layers, each of which performs a specific function to ensure the reliability and durability of the product.

Main design elements of the high pressure hose:

1. Inner layer (sealing):

• Made from synthetic rubber or thermoplastic materials.
• Provides tightness and resistance to chemical influences of the working fluid.

2. Reinforcing layers:

• They are braids or spirals made of high-strength steel or synthetic fibers.
• Provide mechanical strength and resistance to high pressure.
• Depending on the working environment and pressure requirements, they can be single- or multi-layer.

3. Outer layer (protective):

• Made from wear-resistant synthetic rubber or polyurethane.
• Protects the hose from external influences such as abrasive wear, ultraviolet radiation, oils and chemicals.

Main characteristics of HHP:

1. Working pressure:

• Can vary from several tens to several hundred bars.
• Must meet the specifications of the hydraulic system in which the hose is used.

2. Diameter:

• The inner diameter varies depending on throughput requirements.
• The outer diameter affects the flexibility and weight of the hose.

3. Temperature range:

• Operating temperatures may vary depending on the material of the inner and outer layers.
• Typically ranges from -40°C to +100°C, but there may be special models for extreme temperatures.

4. Compatibility with working fluids:

• Hoses must be resistant to various types of hydraulic fluids, such as mineral oils, synthetic fluids and water-glycol mixtures.
