PIPE CONNECTION STRUCTURE CAPABLE OF FIRMLY CONNECTING PIPES WITHOUT WELDING BY DEFORMING ENDS OF PIPES TROUGH PLASTIC DEFORMATION AND INTERCONNECTING THE PIPES

摘要

PURPOSE: A pipe connection structure is provided to facilitate coupling of pipes and to make a coupled part stand the inner pressure of the pipes, by firmly combining plastic deformed parts of the ends of the pipes to a connector. CONSTITUTION: A pipe connection structure comprises a pipe connector(10) formed in a cylinder shape, a sealing ring, and at least one pipe end(2,4). In the pipe connector, at lest one packing groove and at least one pipe combining groove are formed to the outer periphery of at least one side. The sealing ring is inserted in the packing groove of the pipe connector. Packing parts(3,3') by plastic deformation are uniformly formed at the upper position of the packing groove and combining parts(5,5') by plastic deformation are uniformly formed at the upper position of the pipe combining groove while the pipe end is fitted into the outer surface of one side of the pipe connector.
