摘要： A plastically radially expansible conduit connection (700) including a first sealing surface (740) disposed proximal to an end of a pin member (730) of the connection and a second sealing surface (744) disposed proximal to an end of a box member (732) of the connection. The first and the second sealing surfaces substantially opposite each other upon connection of the box member and pin member. The connection also includes a first clearance surface (738) proximal to the first sealing surface on the pin member and a second clearance surface (742) proximal to the second sealing surface on the box member. The first and second sealing surfaces include an anti-rotation device (702). The first and second clearance surfaces and the first and second sealing surfaces each have a diameter such that prior to plastic radial expansion of the box member and the pin member, the clearance surfaces are proximal to each other and do not contact each other and the anti-rotation device is not engaged. After plastic radial expansion, the first and the second sealing surfaces develop a contact pressure, the clearance surfaces remain out of contact, and the anti-rotation device is engaged.
