Polyurea technology is not new to pipelining work, with basic application dating back more than 15 years. Much of this work was either performed by hand spraying (large diameter pipe) or simple robotic systems for individual joint sections of pipe. Continued work over the years has proven that in-place pipelines can be commercially completed by robotic systems and recent work has even shown that in addition to long, straight runs, robotic developments h'ave allowed for lining both 45° and 90° radius bends in a pipeline system.
