Generally speaking, the rubber used for conveying oil is called oil pipe, and those rubber pipes with oil resistance and oil resistance are called oil-resistant rubber pipes. What we’re talking about today is how to choose an oil resistant hose:
   What suits you is the best. The choice of oil resistant hose can not blindly pursue excellent function. You should choose the hose that suits your needs, otherwise you will not be able to make full use of the hose, which may also lead to wasted resources.
  The first thing to check is the temperature of the working environment.
   Due to the difference in materials and additives, the temperature resistance of each variety and model of oil resistant hose will also vary. Exceeding the upper temperature limit can cause problems such as rapid hose aging and loss of plasticizer, which can significantly reduce hose life and performance. Therefore, the temperature adaptation range of the oil-resistant pipe should be higher than the instantaneous maximum temperature during normal operation.
  Second, check the pressure resistance of the rubber hose.
   When the oil-resistant pipe conveys the material, the material is conveyed by pressure discharge and vacuum suction. This will put some pressure on the rubber hose. If the pressure resistance of the rubber hose is not enough, so that the pressure of the material at work is greater than the upper limit of the rubber hose, it will cause more or less damage to the structure of the rubber hose. In the long run, rubber hoses have low performance until aging and damage. At the same time, the inner diameter of the rubber hose should also be related to the compression resistance of the rubber hose to a certain extent, because the material with the same pressure will pass more pressure when passing through the small inner diameter rubber hose, and when passing through the large inner diameter rubber hose. , part of the delivery pressure will be reduced.

 
  Assembly of hoses should also be considered.
   If the length of the rubber hose is too long, the rubber hose will be severely bent during the installation process, which is not only bad for the transportation of the material, but also increases the pressure at the bend. There may also be a risk of damage due to shock and friction during equipment operation. However, we cannot choose rubber hoses with tight lengths, because at low temperatures, the hardness of the rubber will increase and the toughness will decrease. If it is tight, it will also damage the hose structure.
