High-Pressure Hoses

This heavy-duty rubber-impregnated high-pressure hose is used to transfer industrial oil or gas. These hoses came into use because of restrictions inherent to rigid pipelines. High-pressure hoses are used where components of the rigid pipeline are connected or the main pipeline has curved path.

Field of Application

These products are relevant for production facilities with pneumatic or hydraulic equipment.

In particular, such hoses are used in:

  • agricultural equipment,
  • construction machinery,
  • forest machines,
  • mining equipment.

Besides, these hoses are essential for proper operation of oil and gas facilities. Flexible high-presure hoses are in demand in municipal infrastructure on a continuous basis, since they are used by various utility service providers. High-pressure hoses can also be used on construction sites.

It is this hose that is used to supply drilling mud to deep wells. Moreover, high-presure hoses are used to transfer various emulsions and liquid fuel.

Design

  • Rubber inner cavity.
  • A metal frame (textile frame is acceptable).
  • A rubber outer layer.

Inner cavity of the hose is leak-proof. It is produced by extrusion. The hoses are made of rubber with improved strength and leak-proofness.

Besides, inner layer is made resistant to stretching, without fail. One more mandatory process requirement is that the hoses are resistant to aggressive chemical media.

Production Features

The intermediate jacket is made of wire or extra strong synthetic yarn. The wire is completely braided around the inner rubber-impregnated layer, forming a robust jacket. For these purposes, special braiding machines are used in a production environment.

High-presure hoses are produced in several design options. So, experts of HydroCube can provide two jackets rather than only one to improve the product strength even more, since it will be operated under high pressure conditions.

A crucial process stage in HydroCube is a hose pressure test.

It includes a number of steps:

  • Measurement of outer length of the hose.
  • Hose cutting off.
  • External cleaning (can be omitted).
  • Internal cleaning (can be omitted).
  • Assembly of a compression coupling.
  • Assembly of a standard adapter.
  • Pressure test.

Then, experts of HydroCube perform testing according to the process requirements. After the hose passes a number of tests, our experts purge it. Only after that, the hose is packed.

Varieties

Various design options of high-presure hoses can be found in the market of special equipment. They vary in operability and operational performance.

Particularly, the hoses specified in catalogues of the relevant stores differ in:

  • Coefficient of resistance to operating medium.
  • Temperature resistance.
  • Working pressure.

Moreover, the main distinctive feature of the high-presure hose is its diameter.

Equipment operated at the moment at various facilities can be completed with high-presure hoses varying in number of armours from 1 to 6.

In addition, high pressure hoses vary in cold resistance index:minimum 2SN / maximum 4SH.

Performance

First of all, the HP hose must be resistant to fractures and mechanical damage. High-pressure operating environment imposes a high responsibility on manufacturers. It is for a reason that these hoses have several jackets made of heavy-duty wire.

In addition to strength, essential specifications include:

  • Allowable bending radius.
  • Maximum pressure.
  • Range of operating temperatures.

Performance standards assume that the HP hose is used at –40 °C to +100 °C. Extra strong hoses can be used under extreme operating conditions, when temperature ranges from –55°C to +155 °C.

Bending radius ensures seamless operation of the hose. It is selected on a case-by-case basis; however, there are general requirements defined by European regulations.
