摘要： A pipe connection has a connecting member (1). The connecting member (1) has a first end face (4), a first conical bore (5), starting to taper from the latter, which defines a first cone angle (11). The connecting member also includes an axial bore length (9) followed by a bore (6). The outside of the connecting member (1) has a threaded portion (3). A nut (13) has a second conical bore (15) tapered in the direction opposite to the direction of the first conical bore (5). The second conical bore defines a second cone angle (16). A through-bore (17) is in the nut (13). A pipe (18) has a pipe projection (19) which extends into the bore (6) of the connecting member (1). A connecting portion (21) is on the pipe (18). A first conical tensioning face (22) which cooperates with the first conical bore (5) is on the connecting portion (21). The first conical tensioning face defines a third cone angle (23) which is greater than the first cone angle (11) and whose axial length of overlap (32) with the first conical bore (5) is smaller than 15% of the axial bore length (9) of the first conical bore (5). The connecting portion (21) has a second conical tensioning face (25) which cooperates with the second conical bore (15). The second conical tensioning face defines a fourth cone angle (26) corresponding to the second cone angle (16). On the radial inside of the first tensioning face (22), an annular recess (28) is arranged. The recess (28) starts from the smallest cone diameter (24) of the first tensioning face (22) and extends over part of the axial length.

摘要： A flared screw fitting has a pipe expanded in an end section into a tulip flare. A connecting piece has a conical stop face situated on an end section, which is joined in the direction of a forward front face of the connecting piece by a groove. An internal mantle surface of a union element contacts an external mantle surface of the tulip flare in an area whose smallest diameter is larger than the smallest diameter of the stop face of the connecting piece. The union element may be provided with an external threaded section which works together with an internal threaded section of the connecting piece.

摘要： A flared screw fitting (1) has a pipe (3) expanding in an end section to form a tulip flare (11) and a connecting piece (2) having a conical stop face (15) situated on an end section, which is a joined in the direction of a forward front face (27) of the connecting piece (2) by a groove (16) for an elastic sealing ring (17) and on which an internal mantle surface (14) of the tulip flare (11) of the pipe (3) is supported, by which the sealing ring (17) is pressed into the groove (16) in the final mounted state of the screw fitting, furthermore, the tulip flare (11), using a union element adjoining its external mantle surface (19), which works together via a threaded section with a corresponding threaded section on the connecting piece (2), may be pressed against the stop face (15) of the connecting piece (2) in the course of tightening of the screw fitting. To avoid destruction of the connecting piece in the area of the groove base, it is suggested that in the hand-tight pre-mounted state of the screw fitting, an internal mantle surface (18) of the union element only contact the external mantle surface of the tulip flare (11) in an area (20) whose smallest diameter (21) is larger than the smallest diameter (22) of the stop face (15) of the connecting piece (2).

摘要： A pipe connection has a aped pipe, a screw fitting body having an internal cone, a union nut, screwable onto the screw fitting body, having an internal clamping face, which, in the operating state of the pipe connection, works together with an outwardly projecting retention face of a retention bulge of the pipe which is produced facing away from the pipe end by reshaping and projects radially outward beyond the outer mantle surface of the pipe, and having an adapter ring which is supported on the side facing toward the screw fitting body by a conical clamping face in the internal cone of the screw fitting body. To provide an alternative pipe connection of this type, the adapter ring may be supported in the operating state on the side facing toward the pipe by a radially running contact face on the radially running front face of the pipe end.

摘要： A threaded connection for easily deformable thin-walled pipes (20) has a connecting member (1) with a cylindrical receiving bore (5) accommodating the pipe (20) and an outer thread (7). A nut (8) is provided with an inner thread (10) which is threaded onto the outer thread (7). The nut (8) has a through-bore (11) for the pipe (20) and a conical bore (13) which widens towards the connecting member (1). The pipe (20), at a distance from its end face (21), has a bulge (23) which is held in a clamped-in condition between the conical bore (13) and a conical supporting face (18) of a separate supporting ring (14). To limit the tightening movement, the supporting ring (14) has a stop face (19) against which the conical bore (13) comes to rest when the nut (8) is tightened. A holding face (17) on the supporting ring (14) is supported against the end face (3) of the connecting member (1). This design achieves advantageous supporting conditions, with the process of tightening the nut (8) remaining unaffected by the radial forces resulting from the axial tensioning force.
