A rubber hose used for delivering oil is called an oil rubber hose. Additionally, it is also known as an oil – resistant hose. A high – quality oil – delivery hose can endure for many years, effectively helping you cut costs. So, how exactly should one select a good oil pipe? In reality, the best choice depends on the specific working conditions.
Firstly, consider the temperature of the workshop
Each hose has varying temperature resistances because of differences in materials and additives. When the max working temperature is exceeded, issues such as rapid aging and the loss of plasticizers will occur. Consequently, this significantly shortens the hose’s service life and impairs its performance.
Secondly, check the pressure resistance of the oil rubber hose
Oil – resistant pipes transport materials through pressure discharge and vacuum suction, which exerts pressure on the fuel hose. However, if the hose’s pressure resistance is inadequate, it will damage the structure. Over time, this leads to a decline in the oil rubber hose’s performance until it ages and fails. Moreover, the inner diameter of the oil – transfer hose is also related to pressure resistance. A smaller inner diameter results in higher pressure, whereas a larger diameter can reduce the pressure to some extent.
Furthermore, take the assembly of the oil rubber hose into account
If the hose is too long, it will be severely bent during installation. This not only hinders the medium delivery but also generates greater pressure at the bend. Besides, it may cause impact and friction during operation. On the other hand, choosing a hose that is too short is also not advisable. At low temperatures, the hardness of the rubber increases while its toughness decreases. A tight – fitting hose will thus damage the hose structure as well.
