  • 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...

  • What is the current situation and future direction of the construction machinery industry?

      With the continuous advancement of technology and the acceleration of industrialization, construction machinery, as an important equipment in modern fields such as construction, transportation, and water conservancy, is playing an increasingly important role. The widespread application of construction machinery not only improves construction efficiency and reduces labor intensity, but also promotes the development of related industries and makes great contributions to the country’s economic construction.   1、 Common Classification of Construction Machinery Engineering machiner...

  • What are the breakthrough points of hydraulic transmission?

    1. Control of oil leakage issues The hydraulic control system has a variety of application scenarios, and it is prone to problems during use, one of which is oil leakage. leakage not only leads to the contamination of hydraulic oil but also severely affects the normal operation of the control system. This is mainly because hydraulic oil plays a crucial role the transmission and control processes of mechanical equipment, and the control of hydraulic oil temperature is particularly strict. If the hydraulic oil operates for a long time in an overhe state, it will affect the normal operation of...

  • Super soft hose

    Speaking of hoses, everyone’s impression might be that they are soft, capable of conveying fluids, and similar to the transparent water pipes at home Before joining the Weilan platform, I also had this understanding. In fact, in the world of hoses, there are many special products, such as the antivehicle pressure hoses introduced earlier. Today, I want to introduce to you the “excellent student” of the hose family – the ultra-soft hose 1. Why choose ultra-soft tubing? In practical applications, the need for special flexible hoses is very common, mainly due to the fo...
