Difference between low pressure rubber hose and high pressure rubber hose

With the gradual improvement of rubber technology, the types of rubber hoses are also increasing, but so far, we often classify them according to the high pressure and low pressure of rubber hoses. What are the advantages of doing so?

Next, the editor will take nitrile rubber hose as an example to explain it to you

First, introduce their classification standards. According to the classification standard, when the maximum pressure that the rubber hose can withstand is not higher than 1.6Mpa, it belongs to the range of low-pressure rubber hose. If the maximum pressure bearing capacity of the rubber hose exceeds 10MPa and does not exceed 100MPa, it belongs to high-pressure rubber hose. The between them belongs to medium pressure rubber hose. If the maximum working pressure exceeds 100MPa, it belongs to ultra-high pressure rubber hose.

Distinguish from purpose. Take the application of nitrile hose in automobile as an example. High pressure nitrile hose and low pressure hose can bear different pressures, so their application range will be the same. Therefore, the low-pressure rubber hose is mainly used for the oil suction port with low pressure, which belongs to the input end. The high-pressure rubber hose is applied to the oil delivery end with high pressure to quickly output fuel for the equipment and ensure the good operation of the machinery.

Distinguish from the process. The production process of high-pressure hose is more complex than that of low-pressure hose. The low-pressure hose only needs to clamp wires or cloth in the skeleton layer to increase its pressure resistance, but these measures are not enough for the high-pressure hose. Some materials, such as canvas, polyester wire and steel wire, need to be added to the skeleton layer of high-pressure nitrile rubber hose to increase the pressure resistance.

In short, when purchasing rubber hose, we must pay attention to the selection of pressure. If the pressure resistance of rubber hose is too large, the work efficiency may be reduced. If it is too small, the pipe body of nitrile rubber hose may be cracked or even broken. If you need to buy rubber hose, you can come to parlmu company for consultation.
