管法兰是机械、石油、化工、水电、冶金、纺织、制药及核电等行业管道系统中应用最广泛的一种可拆连接件 ,其作用是借助连接螺栓压紧密封垫片 ,使垫片在螺栓压紧力的作用下发生弹性变形或塑性变形 ,以便填塞住法兰密封面间的间歇而达到密封的目的。多年来世界各国一直致力于管
Pipe flanges are the most widely used type of removable connectors in the piping systems of machinery, petroleum, chemical, hydropower, metallurgy, textile, pharmaceutical and nuclear power industries. Their function is to compress the gasket by means of connecting bolts, Under the action of the bolt pressing force, elastic deformation or plastic deformation occurs so as to fill the gap between the sealing surfaces of the flanges and achieve the purpose of sealing. For many years, all countries in the world have been devoted to control
