Number of Steel Wire Layers And Weaving Methods of Hydraulic Hoses

In hydraulic systems, hydraulic hoses are key components for transmitting hydraulic energy, and their performance directly affects the safety and efficiency of the entire system. The number of steel wire layers and the weaving method of hydraulic hoses are important factors that determine their core performance such as pressure-bearing capacity and flexibility.

The number of steel wire layers in hydraulic hoses is designed according to the pressure requirements of the application scenario. Common structures include single-layer, double-layer, three-layer and even multi-layer steel wires. Single-layer steel wire hydraulic hoses are suitable for low-pressure environments, such as auxiliary connections in some small hydraulic equipment. While ensuring basic pressure-bearing capacity, they have good flexibility and are more convenient to install. Double-layer steel wire hydraulic hoses can withstand higher pressures and are widely used in medium-pressure systems such as construction machinery and agricultural machinery. Their structural stability is stronger, enabling them to cope with more complex working conditions. For high-pressure hydraulic systems, such as large industrial hydraulic equipment, hydraulic hoses with three or more layers of steel wires are often required. The multi-layer steel wires cooperate with each other to form a strong pressure-bearing barrier, ensuring that there are no safety hazards such as rupture under high pressure.

The weaving method is also a key factor affecting the performance of hydraulic hoses. At present, the mainstream weaving methods are cross weaving and spiral weaving. Cross weaving involves weaving steel wires on the outer layer of the hose at a certain angle to cross each other. This method gives the hydraulic hose good impact resistance and structural stability, enabling it to maintain good performance when the pressure of the hydraulic system fluctuates, and it is often used in occasions with high requirements for stability. Spiral weaving is where steel wires are wound around the hose in a spiral shape. This weaving method makes the hydraulic hose more flexible and performs well in hydraulic systems that require frequent bending and movement, such as hydraulic connecting pipelines in some automated production lines.
