Prefabricated overhead heat insulation pipe

Abstract

The invention provides a prefabricated overhead heat insulation pipe. In order to solve the problems that when an overhead pipe delivers hot air at a long distance, heat loss is high, and the construction cycle is long, according to the scheme, the prefabricated overhead heat insulation pipe comprises a working pipe. The prefabricated overhead heat insulation pipe is characterized in that the working pipe is wrapped in an inorganic heat insulation layer, an organic heat insulation layer and an outer protection pipe in sequence, and a protection layer is arranged between the inorganic heat insulation layer and the working pipe; longitudinal joints and transverse joints of the inorganic heat insulation layer, the organic heat insulation layer and the outer protection pipe are all in lap joint in a step shape in a staggered mode; the protection layer is connected in a pressed mode; the lap joint of the inorganic heat insulation layer and the organic heat insulation layer is provided with gaps. According to the measures, compared with a traditional prefabricated overhead heat insulation pipe, the prefabricated overhead heat insulation pipe is lower in heat loss, shorter in construction cycle and more environmentally friendly.

Description

technical field The invention relates to an optimized heat transmission pipeline technology, in particular to an optimized prefabricated overhead thermal insulation pipeline for steam transmission. Background technique During the construction of the pipeline network of the heating company, the heat loss of the pipeline is a very important indicator of pipeline construction. With the emphasis on environmental protection from all walks of life, small coal-fired boilers used for district heating will be gradually dismantled, and the required heat energy will be centrally supplied by large power plants using long-distance heating networks, which will require more heat loss control for thermal insulation pipes. high. During the transmission process of traditional overhead steam pipelines, due to temperature differences and other reasons, heat exchange occurs between the transported medium and the surrounding environment, which will inevitably generate a large amount of heat loss...
