A STABILISER AND WEAR RESISTING BAND FOR ROTATING DRILLING EQUIPMENT PIPE AND TOOL JOINTS

摘要

A stabiliser or wear resisting band for drilling or casing drilling or running casing tubulars, comprising a cylindrical body formed in-situ by moulding around a pipe or tool joint, the body of the tool formed from a base material that can be one of an elastomer, semi-crystalline or amorphous polymer, a thermoset material, or a cross-linked material. Also, a method of forming a stabiliser or wear resisting band comprising the steps of placing a mould around a drill pipe tool joint, drill pipe or casing, heating the mould, processing the moulding base material in a high temperature melter, and delivering the moulding base material to the mould via a screw and/or ram arrangement, and a heated barrel or barrels, and/or an insulated line or lines.
