  • Industrial hose working pressure and burst pressure

    The working pressure and burst pressure of industrial hoses are the most important parameters in their design and application, which directly determine the safety and reliability of hoses under specific working conditions. Here is a more detailed explanation of the two parameters: Working pressure: Working pressure refers to the hose in normal working conditions, can continue to withstand the internal pressure, without leakage, deformation or damage. It mainly depends on the hose material, structure, wall thickness, diameter and the working environment of the temperature, media properties ...

  • What tests do hydraulic hoses need to undergo before leaving the factory?

    1. Salt spray test Testing method: Salt spray testing is an accelerated testing method that first atomizes a certain concentration of salt water and then sprays it into a closed constant temperature box. By observing the changes in the hose joint after being placed in the constant temperature box for a period of time, the corrosion resistance of the joint can be reflected. Evaluation criteria: The most common criterion for evaluation is to compare the time it takes for oxides to appear on the joint with the expected value during design to determine whether the product is qualified. For exam...
