Problems solved by technology
Liquid natural gas has a certain viscosity, and the insulation performance of existing natural gas transportation pipelines is poor. It is easy to affect the normal transportation of natural gas when the external environment temperature is very low, such as winter. In addition, natural gas leaks during the transportation process, which is not easy to detect

The invention discloses a natural gas conveying pipeline, and relates to the technical field of natural gas conveying pipelines. The natural gas conveying pipeline comprises an outer pipe body and inner pipe bodies; the inner pipe bodies which are coaxially distributed are installed in the outer pipe body; a cavity is formed between the outer pipe body and the inner pipe bodies; ports in the two sides of the cavity are sealed through two end covers, respectively; the outer sides of the inner pipe bodies are sleeved with linings; the linings are located in the cavity; and the linings divide the cavity into a first cavity body and a second cavity body. The inner pipe bodies are used for conveying natural gas, the outer pipe body sleeves the outer sides of the inner pipe bodies, and the cavity is formed, so that the effects of heat blocking and heat preservation are achieved, the influence of the external temperature on the gas pressure in the inner pipe bodies is reduced, and the stability of the natural gas conveying process is guaranteed.
Description
technical field [0001] The invention belongs to the technical field, in particular to a natural gas transmission pipeline. Background technique [0002] Natural gas is a high-quality fuel and chemical raw material. Natural gas extracted from oil fields is compressed into a liquid state and then transported through pipelines in order to facilitate transportation. Liquid natural gas has a certain viscosity, and the insulation performance of existing natural gas transportation pipelines is poor. When the external environment temperature is very low, such as winter, it is easy to affect the normal transportation of natural gas. In addition, natural gas leaks during transportation, which is not easy to detect. Contents of the invention [0003] The purpose of the present invention is to provide a natural gas transmission pipeline, which is used to transport natural gas through the inner pipe body, and the outer pipe body is sleeved on the outside of the inner pipe body, and fo...
