Flange for pipe joints with pipes leading fluids under high pressure, where the flange comprises a contact surface (6, 7; 6a, 7a) which, when the securing bolts (3) for the pipe joints are not tightened, form an outwards directed angle to each other, and being forced towards each other when the securing bolts (3) are tightened. The flanges may also comprise outer and inner depending sections (8, 9; 10, 11) for further tightening effect, and may additionally possibly comprise washer/gasket grooves (12) and washers/gaskets (20). |
