Well String Centralizer and Method of Forming

A wellstring assembly comprising;

• a tubular section and a tubular device including a bore therethrough, the tubular device installed on the tubular section with the tubular section extending through the bore, the tubular device further including a body having a first end and a second end, the first and second ends extending circumferentially about the bore, the body being formed of a first material;
• and a band embedded at least in part in the body substantially encircling the bore and positioned adjacent at least one of the first end and the second end, the band formed of a second material more durable than the first material and including an installation portion with a plurality of material engagement extensions formed as returns and about which the first material is positioned.

A method for manufacturing a centralizer, the method comprising:

• providing a band for mounting adjacent an end of a centralizer body to be formed, the band including an installation portion with a plurality of material engagement extensions forming returns and applying a first material selected to form the centralizer body over at least a portion of the installation portion of the band such that the material forming the body is positioned about the returns of the material engagement extensions.
