Abstract

The invention discloses a device for preventing a petroleum pipeline from being frost-cracked in severe cold weather. The device comprises a pipeline assembly, an is characterized in that the pipelineassembly comprises an inner pipe body 1, an outer pipe body 2, a first ring part 3 and a second ring part 4; the inner pipe body 1 and the outer pipe body 2 are coaxially arranged; and the inner pipebody 1 is fixedly connected with the outer pipe body 2 through the first ring part 3 and the ring part 4. The device has the beneficial effects of capability of automatically heating, reducing the pipe frost-cracking risk, and providing the frost resistance of a pipeline.

Description

technical field [0001] The invention relates to a mechanical device, in particular to an oil pipeline device capable of avoiding severe cold and cracking. Background technique [0002] Oil pipelines will freeze and crack in the severe winter, and there is no device that can prevent pipelines from freezing and cracking in the prior art. Contents of the invention [0003] Integrating the deficiencies of the background technology, the present invention provides an oil pipeline device that avoids freezing and cracking in severe cold. The device can heat itself, reduces the risk of freezing and cracking the pipeline, and improves the freezing resistance of the pipeline. [0004] The present invention provides the following technical solution: the oil pipeline device of avoiding freezing and cracking in severe cold, including a pipeline assembly, characterized in that the pipeline assembly includes an inner pipe body 1, an outer pipe body 2, a first annular member 3, a second an...
