The stop collar may also include a shield disposed around at least a portion of the flexible member, to protect the flexible member in a downhole environment. The stop collar may also or instead include an adhesive disposed radially between the flexible member and the tubular.

WRAP-AROUND BAND AND SLEEVE ATTACHMENT APPARATUS FOR AN OILFIELD TUBULAR
An attachment apparatus for attaching to a tubular. The apparatus may include a flexible member extending circumferentially around the tubular more than once. A tension force on the flexible member may cause the flexible member to apply a first radially-inward gripping force on the tubular. An annular sleeve may be positioned radially-outward from the flexible member. The sleeve may apply a second radially-inward gripping force on the flexible member and the tubular.
A method of forming a centralizer where a flat plate is created into a tubular where the flat plate is typically rolled so that two sides of the plate contact one another and are then linked, typically by welding. Openings are then created in the tubular such that there are no comers or other points that stress cracks may originate. Once the openings are created the remaining material between adjacent openings forms ribs. The openings created in the tubular are generally aligned with the long axis of the tubular. The material, at the upper and lower end of the flat plate where openings were not created serve as circumferential collars. The ribs may be radially outwardly expanded in order to provide adequate stand-off. In many instances the ribs will also be hardened by heat treating or other hardening processes.
