The invention discloses a petroleum and natural gas temperature control pipeline. A groove is formed in the outer wall of a body of a petroleum and gas transmission pipeline, and a spiral heating metal coil is wound in the groove, so that a heating layer is formed. A high-temperature-resistant thermal insulating layer is connected to the heating layer in a sleeving mode. The head and the tail of the heating metal coil are located at the two ends of the petroleum and gas transmission pipeline, the head end and the tail end of the heating metal coil are connected with a peripheral storage battery and a peripheral temperature control device, and the storage battery is connected with a solar panel. Multiple heat preservation layers are connected to the exterior of the petroleum and gas transmission pipeline in a sleeving mode, and nonmetal threaded rods are arranged between every two adjacent heat preservation layers and fixed to the outer wall of the petroleum and gas transmission pipeline. Sleeves are connected to the outer sides of the nonmetal threaded rods in a sleeving mode, sealing plates are fixed to the upper end face and the lower end face of each sleeve and connected with the corresponding nonmetal threaded rod in a threaded mode, and handles are fixedly arranged on the surface of each sealing plate on the upper portion. The sleeves are arranged in the mode of penetrating through butt-joint heat preservation rings, and the corresponding butt-joint heat preservation rings are connected between every two adjacent heat preservation layers in a butt joint mode. The petroleum and natural gas temperature control pipeline can solve the problems of heat dissipation and freezing blocking of an existing petroleum and natural gas transmission pipeline.
Description
technical field [0001] The invention relates to the related technical field of oil and gas pipelines, in particular to an oil and gas temperature control pipeline. Background technique [0002] Oil and natural gas, the main objects of geological exploration, oil is a viscous, dark brown liquid, known as "industrial blood", natural gas is a gas mainly composed of hydrocarbons and contains non-hydrocarbons fuel and chemical raw materials. [0003] In the prior art, during the transportation of oil and gas in the oil and gas pipeline, the temperature of the oil and gas will change due to the change of the ambient temperature. In the cold winter, especially after the temperature drops in the north, the viscosity of the oil rises. Changes in the phase state of natural gas affect the flow of oil and natural gas in the pipeline. Freeze blockage and explosion often occur, and back pressure is formed, which affects the efficiency of oil and gas transportation, and in severe cases af...
