    摘要： An apparatus and method for radially expanding and plastically deforming a tubular member. The apparatus includes a support member, an expansion device coupled to the support member and at least one of a cutting device coupled to the support member, an actuator coupled to the support member, a sealing assembly, or a packer assembly coupled to the support member. The apparatus may further include a gripping device for coupling the tubular member to the support member. The expansion device may be used for radially expanding and plastically deforming the tubular member which may be coupled to the support member. The cutting device may be used for cutting the tubular member. The actuator may be used for displacing the expansion device relative to the support member. The sealing assembly may be used for sealing an annulus defined between the support member and the tubular member.
