<p>PURPOSE: A rotary-type pipe connection device which facilitates manufacturing work by simplifying a structure of pipe connection part is provided to prevent the separation of the connected part of pipes due to the pressure of fluid. CONSTITUTION: A rotary-type pipe connection device comprises flange parts(10,50), a support groove part(20), a stopping projection part(30), and a packing member(40). The flange parts are formed in one and the other pipes(1,3), respectively. The flange part of the other pipe adheres closely the packing member to the flange part using a bolt member(5) and a screwnut(7). A coherent stripe adhering closely the packing member is formed in the inner surface of the flange part. The stopping projection part is projected in the exterior of the other pipe.</p> |
