Abstract: This invention offers a method to install a wear-resistant polymeric sleeve in a pipe bend stiffener with a metal inner wall, including the following steps: calculate thickness of the internal wall of the stiffener that can removed; remove the thickness of at least a portion of the calculated inner wall; and apply a polymeric material sleeve in the inner wall of the stiffener, where the polymeric material sleeve has the thickness of the inner wall removed.
