National standard rubber joints have good repetitive displacement (change) reducibility and can provide large directional compensation in a small size range, which can better eliminate the multi-directional errors arising from the installation of various pipeline connections.
Do not use defective national standard rubber joints for installation. National standard rubber joints can be used for lifting and conveying raw water and sewage, feed water and circulating water of thermal power plants, metallurgical industry, condensate, pipeline transportation of chemical substances in chemical industry, petrochemical industry, dilution and connection between long and short distance pipelines in other industries. Because rubber has high abrasion resistance, it is also suitable for low-temperature transportation of granular and powder and gas in all industries. When the pipeline medium is more special, special rubber is needed to cope with it. Such as oil resistant national standard rubber joints, acid and alkali resistant national standard rubber joints, etc.
