发明名称 CASING WEAR BAND AND METHOD OF ATTACHMENT
摘要 A crimpable wear band (105) tool has been invented for installation on casing (6), used in well bore drilling. A wear band (105) is provided having a cylindrical body which when coaxially placed over a pipe and substantially radially inwardly displaced at a plurality of points (i.e. crimped) about the circumference of a section of cylindrical body, attaches to the pipe to create a connection having structurally significant axial and torque load transfer capacity. When crimped according to the methods of the present invention, the load transfer capacity of the connection between the wear band (105) tool and the pipe (6) can be arranged to substantially prevent significant relative movement of the wear band tool on the pipe under loads that may be encountered when using one or more of the pipes as components of a tubular string used for drilling or running the casing in to complete a well bore.
