Abstract
The utility model discloses a temperature-sensing thermal insulation petroleum pipeline. The temperature-sensing thermal insulation petroleum pipeline comprises a pipe shell (1), a polyurethane thermal insulation layer (2), a high-density polyethylene layer (3) and temperature sensors (4), wherein the polyurethane thermal insulation layer (2) is arranged on the outer layer of the pipe wall of the pipe shell (1); the temperature sensors (4) are arranged in the polyurethane thermal insulation layer (2); and the high-density polyethylene layer (3) is arranged on the outer surface of the polyurethane thermal insulation layer (2). According to the temperature-sensing thermal insulation petroleum pipeline, the thermal insulation layer is arranged on the outer layer of the pipe wall of the pipe shell, and the temperature sensors are arranged in the thermal insulation layer. As the thermal insulation layer is made of a polyurethane material which is low in thermal conductivity, and the temperature sensors are arranged in the thermal insulation layer, the use condition of the pipeline can be effectively monitored through a computer terminal.
Description
Technical field
The utility model patent belongs to the production field that polyurethane is used in insulation pipe, is specifically related to a kind of thermal insulatnig petroleum pipeline road that carries out the thermal insulation layer monitoring.
