Wire rod hydraulic hoses are indispensable connecting components in hydraulic systems, and their performance directly affects the efficiency and safety of the entire system. When selecting wire rod hydraulic hoses, it’s essential to understand their pressure index for optimal application in various situations.

Definition of Pressure Index
The pressure index of a wire rod hydraulic hose refers to the maximum pressure it can withstand. Generally, it’s classified into three levels: low pressure, medium pressure, and high pressure, with pressure indices of 6.3 MPa, 16 MPa, and 32 MPa, respectively.
Relationship between Pressure Index and Hose Size, Thickness, etc.
The pressure index of a hose is related not only to its material but also to its size and thickness. When selecting hoses, we need to consider the actual working environment and conditions to choose the correct size and thickness to ensure the accuracy of the pressure index.
How to Correctly Select the Pressure Index of a Hose
Correctly selecting the pressure index of a wire rod hydraulic hose is a crucial prerequisite for ensuring the normal operation of the hydraulic system. When selecting hydraulic hoses, we need to understand the following points:
(1) Working pressure: The pressure index of the hose needs to be determined based on the actual working pressure to avoid hose rupture caused by using a hose with a low pressure index subjected to high pressure.
(2) Working temperature: The working temperature range of the hose needs to meet the temperature requirements of the actual working environment to avoid hose aging or hardening due to excessively high or low temperatures, thus affecting its service life.
(3) Medium: When selecting suitable steel wire hydraulic hoses, the properties of the actual medium need to be considered, such as the corrosiveness and viscosity of the medium.
(4) Safety factors: When selecting hoses, the safety factors of the application environment need to be considered to avoid hose rupture caused by using a hose with a low pressure index subjected to high pressure, which could harm personnel and equipment.
How to avoid hose problems
During the use of steel wire hydraulic hoses, aging and damage may occur. Here are some suggestions to avoid hose problems:
(1) Regularly check the condition of the hoses and whether replacement is necessary. (2) Select suitable steel wire hydraulic hoses, taking into account the environment and conditions of the actual working environment.
(3) Keep the hoses clean and dry, and avoid contamination and moisture.
(4) When connecting the hoses, ensure the tightness of the flanges, sealing rings, and bolts.
