What are the characteristics of EPDM rubber joints?
Due to the unique advantages of EPDM rubber joints, other rubber strips are not durable in many practical environmental situations, such as the aging resistance, corrosion resistance, water vapor resistance, superheated water resistance, elasticity, etc. among them. What are the characteristics of EPDM rubber joints?
 
EPDM EPDM rubber joints have the following characteristics: low density, the density of EPDM rubber joints is about 0.5~0.6g/cm3, which is one half of common rubber strips, or even lower. Excellent heat insulation. Because there are a lot of bubble holes in the structure of EPDM EPDM rubber joints, the thermal conductivity of the gas in the bubble holes is much lower than that of solid rubber, so the thermal conductivity of the foam rubber strip is very low. The sound insulation effect of EPDM EPDM rubber joints is achieved by absorbing acoustic energy so that acoustic waves cannot be transmitted by reflection. High specific strength. The mechanical strength of EPDM EPDM rubber joints decreases with the increase of foaming times.
 
Rubber joints are mainly rubber and plastic products used to connect the middle of the pipeline with its flexible connection effect, also known as flexible joints, flexible rubber joints, plastic shock absorbers and so on. Double sphere rubber joint uses the elasticity of plastic, high sealing, media resistance, aging resistance and radiation resistance, etc., and selects the degree, hot and cold alternating high degree of polyester cord fabric intersection with its compound, through high pressure, high heat abrasive vulcanized rubber into. No counter-thrust: because the main material is non-metallic material, no force transmission. Energy-saving flexible rubber joints have significant vibration and noise reduction expected effects in the centrifugal pump mouth transformation. As the rubber joint digests the vibration of the pipeline and prevents the pipeline ground screw from falling. Thus flexible rubber joints are a better choice for vibration and noise reduction when compensating for off-set concrete cracks. When rubber joints cannot be fixed for various reasons, other rubber joints should be used to fix them. The normal available medium of plastic ball joint is temperature -℃ general water, medium such as: oil, strong acid, strong alkali, continuous high temperature and other corrosion, hard texture, should choose the corresponding special durable raw material rubber joints, can not blindly follow the trend of mixed or generic. The quality of the connection flange is equally critical, the normal available medium for general-purpose bendable rubber joints is the temperature in - ℃ general water, in the centrifugal water pump import and export trade installation of rubber joints, prohibit the joints at the limit of the disturbance deviation and error situation, rubber joints hanging in the air water supply and drainage or high-level pipeline should have special positioning device on.
