Indiana University Steam Line Restoration

Project Details

TST was contracted by Indiana University (Bloomington) to upgrade the efficiency of several sections of thermally-degraded buried steam distribution piping on campus. Seven (7) different sections of 4” Thermacor DuoTherm 505 piping at Beach Hall, Pine Hall, Cypress Hall, Linden Hall, Birch Hall, Hickory Hall, and Cedar Hall were thermally restored after ConduFill® was injected into the void between the outer casing and the carrier piping. Each 15 LF section of piping that was restored ran underneath the building and came up through the floor of a mechanical room. TST was able to park it’s Mobile Pumping Unit (MPU) close enough to each mechanical room so that the formulation could be injected through tubing that was strategically inserted between the outer casing and the steam line. The presence of ConduFill® in the system allows the university to restore thermal efficiency and reduce the likelihood of excess heat and vapor entering the building through the piping system. The project was completed over a two day period in late January 2018.
