The balance between the wall thickness and performance of rubber oil hoses

In the modern industrial field, rubber oil hoses are important components of hydraulic systems and transmission fluids, and the stability and reliability of their performance are crucial. The wall thickness of rubber oil hoses, as one of the key factors affecting its performance, is a parameter that designers and users need to focus on. As the saying goes, the thicker the wall of the rubber oil hose, the stronger its pressure resistance, and this view is true in most cases. However, there are always two sides to things, and too thick a wall may also bring a series of unexpected problems. Therefore, when choosing rubber oil hoses, we need to weigh the wall thickness and flexibility according to the actual application scenario to find the best balance point.

First, let's explore the relationship between the wall thickness of the rubber oil hose and its pressure resistance. Wall thickness is an important supporting structure for rubber oil hoses to withstand internal pressure. In the hydraulic system, the oil pipe needs to withstand a high working pressure. If the wall thickness is insufficient, it may cause the oil pipe to expand or even rupture under high pressure, thereby causing system failure. Therefore, increasing the wall thickness can effectively improve the pressure resistance of the oil pipe and ensure the stable operation of the system under high pressure. Especially in some application scenarios with extremely high pressure requirements, such as heavy machinery, aerospace and other fields, it is particularly important to choose rubber oil hoses with thicker wall thickness.

However, the thicker the wall thickness, the better. Although the excessive wall thickness improves the pressure resistance, it may also cause the rubber oil hose to become stiff, affecting its flexibility and service life. The rubber material itself has a certain elasticity, which enables the oil pipe to maintain good shape recovery and sealing under complex working conditions such as bending and torsion. However, if the wall thickness is too thick, the bending radius of the oil pipe will increase, the flexibility will decrease, and it will be difficult to adapt to complex installation spaces and motion trajectories. In addition, excessive wall thickness may also increase the weight of the oil pipe, which will have a negative impact on the overall performance and efficiency of the system.

More importantly, excessive wall thickness may cause cracks, aging and other problems in the rubber oil hose during long-term use. This is because when the rubber material is subjected to continuous stress, stress relaxation and creep will occur. The internal stress distribution of the oil pipe with too thick wall thickness is more complex, and stress concentration areas are prone to occur, which accelerates the aging and damage of the material. Therefore, while pursuing pressure resistance, we cannot ignore the impact of wall thickness on the flexibility and service life of the oil pipe.

So, how to find the best balance between wall thickness and flexibility? This needs to be analyzed specifically according to the actual application scenario. For occasions that need to withstand high pressure and the installation space is relatively fixed, rubber oil hoses with thicker walls can be selected to ensure the stability and safety of the system. For occasions that require frequent bending, twisting or limited installation space, the wall thickness should be appropriately reduced to improve the flexibility and adaptability of the oil pipe.

In addition, when selecting rubber oil hoses, it is also necessary to consider various factors such as material type, processing technology, and use environment. Different types of rubber materials have different oil resistance, temperature resistance, and wear resistance, and should be selected according to specific working conditions. The quality of the processing technology will also directly affect the quality and performance of the oil pipe, so qualified and experienced manufacturers should be selected for cooperation. Factors such as temperature, pressure, and fluid properties in the use environment will also affect the selection of oil pipes, and comprehensive evaluation and testing are required.
