What Is The Bursting Pressure of Hydraulic Tubes?

Hydraulic tubes are used to transmit hydraulic oil and realize the transmission and control of hydraulic energy. Hard pipe is mainly seamless steel pipe, while hose is pipes formed by layered wire mesh and rubber bending. ‌

The bursting pressure is usually 4-5 times its working pressure, generally between 100MPa and 150MPa, and the specific value depends on the material and diameter of the pipe. The main reasons for hydraulic tube bursting include the use of inferior pipes, excessive pressure in the hydraulic system, and high temperature of hydraulic oil. Preventive measures include the selection of qualified hydraulic tubes, reasonable setting of system pressure, and control of hydraulic oil temperature.

Hydraulic tubes are an indispensable part of the hydraulic system, and the pressure they withstand has a certain limit. So, what is the bursting pressure of hydraulic tubes?

Analysis of the causes of hydraulic tube bursting

There are many reasons for hydraulic tube bursting, and the common ones mainly include the following points:

1. Use of inferior hydraulic tubes. There may be hydraulic tubes of substandard quality on the market, and their performance and reliability are far inferior to regular products. Using such pipes will greatly increase the risk of bursting.

2. The hydraulic system pressure is too high. If the preset pressure of the hydraulic system exceeds the bearing limit of the hydraulic tube, the pipe may burst.

3. The hydraulic oil temperature is too high. High temperature will affect the sealing of hydraulic components and even cause deformation of components, which will cause bursting.

Burst pressure of hydraulic tubes

The bursting pressure of hydraulic tubes refers to the pressure value at which the hydraulic tube is destroyed under the action of internal pressure. This value is usually 4-5 times the working pressure of the hydraulic tube. According to Chinese standards, the working pressure of hydraulic tubes is divided into four types: low pressure, medium pressure, high pressure and ultra-high pressure. The bursting pressure of hydraulic tubes is generally between 100MPa and 150MPa, but the specific value will be affected by many factors such as the material, diameter, wall thickness and use environment of the pipe.

Preventive measures for hydraulic tube bursting

In order to prevent hydraulic tube bursting, the following measures can be taken:

1. Choose hydraulic tubes from regular big brands to ensure that their quality and performance meet the standards.

2. Reasonably set the pressure of the hydraulic system to avoid excessive pressure causing pipe bursting.

3. Control the temperature of the hydraulic oil to prevent hydraulic tube bursting caused by high temperature.

Summary

Through the above analysis and preventive measures, we can effectively improve the safety and reliability of the hydraulic system and reduce the risk of hydraulic tube bursting. At the same time, regular inspection and maintenance are also essential to ensure the normal operation of the hydraulic system.
