摘要： A device which is expandable to engage the interior of a tube, for example the casing of an oil well, comprises first and second tubular members in partial telescopic engagement with each other, the first tubular member having an end region which is received on the second tubular member and which is expandable radially outwardly to engage the interior of the tube. The second tubular member has tapered regions which, when forced into the end region, will cause radial expansion of the end region. The taper angle of the second tapered zone is less than the taper angle of both the first tapered zone and the third tapered zone. The fourth tapered zone preferably has a taper angle which is greater than that of the second tapered zone and less than that of the third tapered zone. In one embodiment, the tapered zones have respective taper angles of 15°, 1°, 5° and 1.25°.

摘要： A connector (1) for connecting to a tubular member has a body (5, 35, 65) with a bore (7, 37, 67) configured to receive the tubular member, the body having a wedge device (10, 40, 70) within the bore adapted to interact with the body to grip the tubular member (15) when the tubular member is disposed within the bore, wherein the wedge device is at least partially helical, and wherein the connector has an anti-rotation device (23, 53, 83) to restrict relative rotation of the wedge device and the body when the tubular is gripped in the bore.
