Abstract
A method for forming a sleeve for wrapping around and insulating a joint of a downhole tubing string is provided. The method includes the steps of providing a mold, applying insulation around the mold, winding an interfacing material around the insulation; and applying a polymer onto the interfacing material to bind to the interfacing material to form the sleeve.

A method for forming a sleeve for wrapping around and insulating a joint of a downhole tubing string, the method comprising:
- providing a mold;
- applying an insulation around the mold;
- winding an interfacing material around the insulation;
- winding a wire, rope, cord or strip or a combination thereof over the interfacing material to provide a reinforcement material;
- and
- applying a polymer onto the interfacing material and the reinforcement material to bind to the interfacing material and to encapsulate the reinforcement material to form the sleeve.

A method for forming a sleeve for wrapping around and insulating a joint of a downhole tubing string, the method comprising:
- providing a mold;
- applying a sheet elastomer around the mold as a base layer;
- applying an insulation around the base layer on the mold;
- winding an interfacing material around the insulation;
- and
- applying a polymer onto the interfacing material to bind the interfacing material to form the sleeve;
- wherein the step of applying the polymer onto the interfacing material to bind to the interfacing material to form the sleeve comprises applying the polymer to at least an end of the sleeve to bind to the base layer at the at least the end of the sleeve;
- and
- wherein the sheet elastomer is compatible with the polymer.
