Abstract

A pipe includes an outer surface with a polyolefin-based protective coating covering a substantial portion thereof. In addition, an end wrap material is disposed on the protective coating proximate to an end of the pipe, where the end wrap material is bondable to a polymer-containing protective material, such as a heat shrink sleeve or cover. The end wrap material can bond a heat shrink cover or sleeve in place over a girth-weld, thus substantially reducing the likelihood of the disbondment or movement of the sleeve from the welded pipe ends over time.
