At least one flange (1; 2; 26) is has a face with a circular groove (6; 7; 27) to at least partly receive a sealing ring (9; 21) which has its ring wall rectilinear as seen in a cross-section when front faces of the pipe flanges are spaced apart. A bottom (13; 14; 28) of the groove (6; 7; 27) exhibits a first transition (15; 16; 29) between the bottom and a radially located inner wall of the groove, and a second transition (17; 18; 30) between the bottom and a radially located outer wall of the groove. The ring (9; 21) in side view exhibits a shape like a truncated cone. The pipe flanges (1, 2; 25, 26) are attached to each other to yield that the flanges (1,2; 25, 26) in operative state are forcibly held in an abutting and facial engagement, and upon tensioning of tensioning means (3, 4) to create said operative state, compressive forces act onto the sealing ring (9; 21) to yield that its wall, as viewed in cross-section, is bent radially to exhibit a curved configuration.
