  • Definition of hydraulic fittings

    Hydraulic systems use hydraulic fittings to connect hoses, valves, fittings, and tubes, and they serve two primary functions: holding and sealing. Below the definition, selection, types, and common features of hydraulic fittings. 1. What is a hydraulic fitting? Hydraulic fittings are used in hydraulic systems to connect hoses, valves, pipes, and tubes. They serve two main functions: holding and sealing. help contain the hydraulic fluid, so none of the fluid can escape the system, and they help direct the flow and maintain system pressure. Since hydraulic systems operate in high-pressure env...

  • Metal hose, learn something new!

    1. Product structure The metal hose is mainly composed of the bellows section and the connecting parts at both ends.  2. Product Applications The metal flexible hoses, used as sensitive elements, shock-absorbing elements, compensating elements, sealing elements, valve elements, and pipeline connection, are widely applied in automatic control and measuring instruments, vacuum technology, mechanical industry, electric power industry, transportation, and nuclear energy industry. Metal bellows are made of different metal materials depending on their intended use. Therefore, the performance and ...

  • In-depth analysis of stainless steel braided PTFE bellows

    In the modern industrial field, pipeline systems, as the core part of fluid transmission, have their performance directly related to the efficiency, safety and product quality of the production process. With the advancement of technology and the continuous upgrading of industrial demands, traditional pipeline materials have become difficult to meet the requirements of extreme working conditions. It is in this context that stainless steel braided PTFE bellows have emerged, and with their unique structure and excellent performance, they become the ideal choice in many industrial fields. The ...

  • The service life of industrial rubber hoses

    The service life of industrial hoses depends on the conditions of use. Moreover, depending on the application, the fluid, temperature, pressure, and frequency use can vary greatly, so there is no specific reference standard. The following is a list of the service life of common rubber hose materials (for reference only, as different working conditions can greatly affect the lifespan Nitrile Butadiene Rubber (NBR/BUNA) 2-5 years Hydrogenated Nitrile Butadiene Rubber (HNBR) 2-5 years Ethylene Propylene Diene Monomer (EPDM) 2-5 years Silicone rubber (SI) 3-5 years Fluororubber (FPM/FKM/VITON) ...

  • The working pressure and burst pressure of industrial hoses

    The working pressure and burst pressure of industrial hoses are critical parameters in their design and application, directly determining the safety and reliability of the hoses under specific conditions. Below is a more detailed explanation of these two parameters: Working Pressure: Working pressure refers to the internal pressure that a hose can continuously withstand under normal working conditions without leaking, deforming, or being damaged. It mainly on the material, structure, wall thickness, diameter of the hose, as well as the temperature and medium properties in the working envir...
