Abstract
An objective of the present invention is to provide a pipe through which fluids can flow, in which thermal insulation in a space between an inner wall and an outer wall is achieved at low cost and high performance. The thermal insulation pipe of the present invention is a thermal insulation pipe formed by a double wall pipe of an inner pipe and an outer pipe. A thermal-insulating material to be filled in a space between the inner pipe and the outer pipe is made from an aerogel having a three-dimensional network structure with a framework constituted by a cluster of aggregation of primary particles. The thermal-insulating material includes fine particles having a three-dimensional network structure with a framework of the primary particles. A preferred form of such a thermal-insulating material is weakly bonded aerogel ultrafine particle generated by crushing at ultra-high speed a low-binding ultrafine aerogel generated from an aerogel with aging conditions during manufacturing process set to a low temperature and short time period.
