The principle of operation of high pressure hydraulic hoses and their characteristics
High pressure hydraulic hose is a type of flexible piping used in hydraulic systems. Its main task is the transportation of liquids for various purposes. These can be soluble and mineral oils, fuels, water emulsions, lubricants.
Functions and features of the use of high pressure hoses
In addition to transporting liquids, the functions of such hoses include:
- Preserving the mobility of individual elements in the system without violating its tightness and integrity. The high pressure hose acts as a flexible pipeline in the joints of mechanisms and machines, mobile working bodies, such as swinging cylinders of dumps and booms of excavators, cranes.
- Ensuring the reliability of the hydraulic system as a whole. The hose is easier and faster to replace than a metal pipe. In addition, high pressure hoses better resist such negative influences as shock, friction and vibration.
High pressure hoses are most often used in such types of systems and transport:
- presses, jacks, turbines, cylinders, pumps and other elements of hydraulic systems;
- trucks and cars;
- machine tools;
- lifting equipment in construction work and in warehouses;
- forestry machinery;
- agricultural machinery;
- drilling machines.

Thermoplastic hoses are used in auxiliary systems for the supply of solvents, alcohols and other special fluids.
There are also high pressure winding and braided hoses.
According to European standards EN853 and EN857, high-pressure braided hoses are divided into:
- 1ST - single-layer braid.
- 2ST - double-layer braid.
- 1SN - thin outer layer and single layer braid.
- 2SN - thin outer layer and double layer braid.
Such hydraulic hoses are used with an average pressure range of 22-40 MPa.
Wheeling high pressure hoses, based on European standards EN856, can be of 4 types:
- 4SP - have 4 layers of metal coil, suitable for medium pressure applications.
- 4SH - are characterized by 4 layers of coil and are used at high pressure.
- R12 - have 4 layers of metal coil, are operated at medium pressure and high temperatures;
- R13, R15 - have 6 layers of coils, suitable for impulse loads in high pressure conditions.
