Klaver, B.W. van de Beld, C. TNO Industrie en Techniek Publication year 2010 Abstract In this paper a large-area heat flux and temperature sensor (HFT) is used for the evaluation of the insulation value of cryogenic pipes. The HFT is flexible and clamp-on. The test method is relatively simple and can be used in-situ. The HFT makes it possible to monitor insulation performance over elongated times and to study localized effects (thermal bridges).The method complies with the Standard Practice ASTM C 1041 - 85 (2007). The method is originally designed for subsea oil pipelines. Three commercial rigid cryogenic pipes are tested, using vacuum, polyisocyanurate and polyurethane insulation. The method is also used on flexible cryogenic pipes.
