Silica gel/polyurethane for pipe-in-pipe system.(MATERIALS)
Advanced Ceramics Report, April, 2007
Cabot Aerogel, a business unit of Cabot Corp, and Corus Tubes, a division of Corus, both USA, have introduced an insulation pipe for use with high pressure high temperature (HPHT) applications. The system is insulated with a silica aerogel using nanotechnology (Cabot's Nanogel) and polyurethane (PU) foam.
Cabot's Nanogel is a hydrophobic aerogel produced as particles each of which consists largely of air (around 95%) contained in nanosized pores that severely inhibit heat transfer through the material.
The system was designed by Corus and combines the ultra-low conductivity and wide temperature stability range of Nanogel with the strong bonding benefits of PU foam. An inner layer of aerogel is placed in direct contact with the high temperature inner...
