PROBLEM TO BE SOLVED: To provide a loose flange type pipe joint which has a packing member comprising a reinforcement ring made of metal and elastic gaskets made of rubber and prevents the elastic gaskets made of the rubber or the like from directly contacting with a fluid passing through a pipe with the reinforcement ring made of the metal.SOLUTION: In a loose flange type pipe joint, a packing member includes: a pair of annular elastic gaskets; a metal reinforcement ring holding the gaskets; and an outer frame body with bolt holes. Annular grooves are provided on side surfaces of the reinforcement ring, and the elastic gaskets respectively fit in the annular grooves.SELECTED DRAWING: Figure 1 【課題】金属製の補強リングおよびゴム製などの弾性ガスケットで構成するパッキン部材を有し、金属製の補強リングによってゴム製などの弾性ガスケットがパイプ内の通過液と直接接触しないルーズフランジ式管継手を提供する。【解決手段】ルーズフランジ式管継手において、パッキン部材は、１対の円環状の弾性ガスケットと、両ガスケットを保持する金属製の補強リングと、ボルト孔付きの外枠体とからなり、該補強リングの両側面に円環状溝を設けて、両円環状溝に弾性ガスケットをそれぞれ嵌合する。【選択図】図１
