Abstract: In view of the problems in the thermal insulation structure of high-temperature pipelines in petrochemical units such as large heat dissipation loss and seriously damaged thermal insulation structure, a new composite thermal insulation structure of nano ceramic fiber thermal insulation material and high-density rock wool pipe is adopted to replace the widely used thermal insulation structures of aluminum silicate fiber cotton, composite silicate and calcium silicate coiled materials. The integral insulation structure, which is characterized by the extremely low thermal conductivity of nano ceramic fiber thermal insulation material and the high strength of high-density rock wool pipe, greatly reduces the heat dissipation loss of high-temperature pipelines and significantly prolongs the service life of insulation structure for high-temperature pipelines.
