ABSTRACT:
A crimpable centralizer has been invented for installation on pipe, such as would be useful in well bore drilling and casing operations. The present invention provides a centralizer 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 the 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 centralizer and the pipe can be arranged to substantially prevent significant relative movement of the centralizer 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 completing well bores.
