Description
本実施例においては、リング5は180度の円弧部材5a及び5bからなるものであったが、180度以下にリング5を分割する場合には、円弧部材は合計で360度になる複数の円弧部材であっても良い。
図7において、圧力配管2に対して溝23が形成される点は実施例1と同じである。また、インサート3およびリング5も同様である。
インサート3のOリング40に対する圧縮は、横孔430に挿入されるボルトを用いて行う。
フランジ500は、圧力配管2を外嵌する中空510を有する直線状の円筒管であり、一方の中空510の入口には、全円周に渡って半径方向外側に後退した段差511bが設けられている。段差511bは、中空510から半径方向に後退すると、圧力配管2の外周に正対する円筒内周面511aに到る。フランジ500は、フランジ400における貫通孔412を有していない。フランジ500には、さらに、中心線Cの方向に、等角度間隔に多数の横孔530を有している。横孔530を利用して、締結ボルトNにより他の機器との接続を行う。
