Abstract

The invention discloses a method, device and system for testing a total heat transfer coefficient from gas to soil. The method comprises the following steps that: gas data and soil temperature data of a to-be-tested gas conveying pipe section are acquired through a data acquisition unit, wherein the data acquisition unit is installed on the to-be-tested gas conveying pipe section and the to-be-tested gas conveying pipe section is any section of a gas conveying pipeline which is put into operation; and according to the gas data and the soil temperature data, calculation is performed to obtain a total heat transfer coefficient from the gas of the to-be-tested gas conveying pipe section to the soil, so as to obtain a total heat transfer coefficient from the gas of the gas conveying pipe section to the soil. Compared with the prior art, by effectively collecting, analyzing and processing parameters such as the temperature of the gas in the gas conveying pipeline and the temperature of the surrounding environment in real time, the total heat transfer coefficient of the gas in the whole pipeline to the soil is obtained by calculating the total heat transfer coefficient of the gas in the single pipeline to the soil, the dependence on manpower is reduced, and the data accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of gas pipelines, in particular to a method, device and system for testing the total heat transfer coefficient from gas to soil. Background technique [0002] At present, when calculating the natural gas pipeline process, such as calculating the gas temperature at any point along the outbound pipeline of the natural gas station, it is generally calculated by referring to the formula 3.3.3 in the current national standard "Code for Design of Gas Transmission Pipeline Engineering" GB50251, but the formula The value of the total heat transfer coefficient from gas to soil in the gas pipeline is not specified in the document; [0003] In the process of gas pipeline process calculation, the total heat transfer coefficient from gas to soil in the gas pipeline is usually selected based on empirical values ​​by referring to relevant literature. The heat transfer from the gas to the soil in the gas pipeline mainly co...
