2SN high pressure hose is used in hydraulic systems for supplying working fluid or removing it. This element is necessary for equipment intended for the production of logging, mining, drilling, construction and repair of highways, and is an important part for special equipment, road transport, mechanical units and installations.
2SN Hose has a two-layer construction of oil-resistant and wear resistant rubber, and is reinforced with a double steel wire braid. Oils, petroleum products (diesel fuel, fuel oil, oil), and other hydraulic fluids are used as a working composition. The 2SN hose has a range of operating temperatures from -50 to + 150 degrees.
Parts are manufactured using the latest equipment from high quality materials. Hoses and hoses can be supplied in a standard type, or at the request of the customer, with the required dimensions and shapes of connecting tips, of any diameter and length.
Design and features
The 2SN hose differs from the modification of the old 1SN model by the presence of a double steel wire cord, the structure consists of 5 layers, each of which is responsible for certain functions:
- outer polymer - rubber layer (wear protection);
- steel reinforcement (increases tensile strength under pressure);
- tubular spacer (separates the cord);
- the second layer of reinforcement;
- oil-resistant polymer rubber layer (protects against the influence of the hydraulic medium, serves as a line).
When working with flammable or expensive materials, it is necessary to use this modification of the hoses. When the first layer ruptures, the liquid does not come out, but closes in the surface contour.
The 2SN hose is intended, among other things, for use in oversized and hard-to-reach places. It can be bent and folded by any method, while the system will not lose the required pressure, and the hose will not rip off the threaded connection.
Features of choice
When purchasing 2SN hoses and hoses, it is necessary to determine the working environment, the products can be designed for water, special-purpose hydraulic fluids or petroleum products. Also, the design of the hoses can be adapted to the universal parameters of the fluid.
In addition, it is necessary to take into account the indicators of the operating and maximum pressure in the system and select a part corresponding to these parameters.
In addition, the length of the hose plays an important role, since with a sufficiently large distance, the product can break off the threaded connections from a sharp pressure surge and the effect of its own weight.
