| New HPHT pipe-in-pipe system Cabot Aerogel and Corus Tubes announced an innovative hybrid insulation pipe-in-pipe system insulated with Nanogel aerogel, a nano-technology enabled silica aerogel, and polyurethane foam. The Corus-designed system combines the ultra-low-conductivity and wide temperature stability range of Nanogel with the strong bonding benefits of PU foam. An inner layer of Nanogel aerogel placed in direct contact with the high temperature inner pipe, and an outer layer of PU foam, creates a bond between the Nanogel layer and the outer pipe. In addition to providing mechanical support, the PU foam compresses the Nanogel aerogel layer, which improves thermal performance. Prototypes are currently undergoing thorough testing at Corus' research and development facility in Rotherham, UK with results expected in April 2007. write your comments about the article :: © 2007 Construction News :: home page |
