Abstract
A flange connection for pipes has a plug connection member having a pipe section and a flange connected to one end of the pipe section, wherein the pipe section has a mounting seat and a sealing seat. The plug connection member also has a first sealing ring seated in an initial position in the mounting seat, wherein the first sealing ring rolls from the mounting seat into the sealing seat and into a sealing position when the pipe section is inserted into a pipe end.
Claims17
A flange connection for pipes, the flange connection comprising a plug connection member comprised of a pipe section and a flange connected to one end of the pipe section, wherein the pipe section has a mounting seat and a sealing seat, wherein the plug connection member further comprises a first sealing ring seated in an initial position in the mounting seat, wherein the first sealing ring is configured to roll from the mounting seat into the sealing seat and into a sealing position when the pipe section is inserted into a pipe end, wherein the flange has an end face with an outer rim and widens from the outer rim radially inwardly in an axial direction of the pipe section and forms a step proximal to the pipe section, wherein the flange connection further comprises a counter member, having a counter flange shaped identically to the flange of the plug connection member, and a clamping device having a cross-section matching a cross-section of the flange of the plug connection member and of the counter flange when positioned with the end faces in an abutting position, wherein the clamping device is configured to clamp the flange and counter flange against one another in the abutting position for securing the flange connection.
A flange connection for pipes, the flange connection comprising a plug connection member comprised of a pipe section and a flange connected to one end of the pipe section, wherein the pipe section has a mounting seat and a sealing seat, wherein the plug connection member further comprises a first sealing ring seated in an initial position in the mounting seat, wherein the first sealing ring is configured to roll from the mounting seat into the sealing seat and into a sealing position when the pipe section is inserted into a pipe end, wherein the sealing seat is a first groove formed in the pipe section, wherein the first groove has a first sidewall proximal to the mounting seat across which first sidewall the first sealing ring rolls when rolling from the mounting seat into the sealing seat, wherein the first sidewall has a height of 25 to 30% of a height of the sealing ring in the sealing position, and wherein the first groove has a flat bottom.
A flange connection for pipes, the flange connection comprising a plug connection member comprised of a pipe section and a flange connected to one end of the pipe section, wherein the pipe section has a mounting seat and a sealing seat, wherein the plug connection member further comprises a first sealing ring seated in an initial position in the mounting seat, wherein the first sealing ring is configured to roll from the mounting seat into the sealing seat and into a sealing position when the pipe section is inserted into a pipe end, wherein the sealing seat is a first groove formed in the pipe section, wherein the first groove has a first sidewall proximal to the mounting seat across which first sidewall the first sealing ring rolls when rolling from the mounting seat into the sealing seat, wherein the first sidewall has a height of 25 to 30% of a height of the sealing ring in the sealing position, wherein the mounting seat is a second groove with a curved bottom and wherein a portion of the pipe section extending between the first and second grooves has a diameter that increases from the second groove to the first sidewall of the first groove, wherein a bottom of the first groove is located at a diameter of the pipe section that is greater than the diameter of the pipe section where the curved bottom of the second groove is located.
