【Abstract】 A kind of sealing plug for pressure test of plastic pipe is designed,which is characterized by free end seal,and the two sealing joints are not connected with each other. The external surface of rigid plastic pipe adopts self locking mechanism,and the inner surface adopts compression mechanism to achieve sealing effect,which meets the requirement of pressure proof seal.更多还原
