a thermal insulation pipe

Abstract

The invention relates to the field of heat preservation devices, and discloses a heat preservation pipe which comprises an inner pipe, wherein the inner part of the inner pipe is used for allowing fluid to be introduced into; at least two heating bands are arranged on the outer wall of the inner pipe; the outer parts of the heating bands are coated with a nanometer material heat preservation layer, a calcium silicate heat preservation layer, a glass fiber reinforced plastic composite material layer and a heat preservation layer in sequence; an outer pipe is arranged at the outer part of the heat preservation layer; a corrosion prevention layer is arranged at the outer part of the outer pipe. According to the invention, the heating bands are arranged in the heat preservation pipe and used for generating heat under the action of an external heating source, and the multiple heat preservation layers are arranged at the outer parts of the heating bands and can be used for preserving heat generated by the heating bands to enable fluid conveyed in the heat preservation pipe to be free of the influences of external environments such as low temperature environment and the like, so that the heat preservation pipe is higher in conveying efficiency when being used for conveying.

Description

technical field [0001] The invention relates to the field of heat preservation devices, in particular to a heat preservation pipe. Background technique [0002] In life, pipelines are often used for fluid transportation. Air-conditioning pipelines, water pipelines, gas pipelines, etc. are all used to transport indispensable necessities in life. However, due to different geographical environments, pipelines often have to bear the pressure from the external environment, such as low temperature, high pressure and corrosion. Especially in low-temperature environments, if the pipeline used to transport fluid does not have insulation performance, it will directly affect the state of the fluid in the pipeline and the transportation efficiency, such as the pipeline for transporting water. When the ambient temperature of the pipeline is low, if the pipeline Without the function of heat preservation, the water in the pipeline will freeze due to the low temperature, making it impossib...
