How serious is the damage that can be repaired with ESR?
Circumferential damage: standard 3D length ESRs are suitable for repairs of girth weld or other type of circumferentially oriented damage with depths up to 80 percent of pipewall thickness around 60 percent of the pipeline circumference. Axial damage: ESRs are suitable for repair of all non-leaking axially oriented pipe body damage involving dents, gouges, cracks, spalling and corrosion.
