Abstract
The polyurea technology is not new to pipelining work, with earlier basic applications 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 pipe lines can be commercially completed as well. More recent work has even shown that in addition to long, straight runs, robotic developments have allowed for lining both 45° and 90° radius bends in the pipe line system. To date, pipe lines of nominal 4” (10 cm) up to 96” (2.4 meter) can easily be accomplished using the polyurea spray elastomer technology and the robotic systems. Newer developments have also demonstrated pipelining of nominal 1” (2.5 cm) diameter with the polyurea technology. These robotic development works hand-in-hand with special performance modified polyurea systems fine tuned to process on the robotic, as well as allowing for application thickness of up to 1” (2.5 cm) in thickness in a single pass. This presentation will discuss these robotic SIPP developments (Sprayed-in-Place-Pipe), polyurea systems (PUA) designed for application work in industrial and water/wastewater applications as well as Industry Standards being prepared for robotic sprayed-in-place pipe.
