Abstract

The invention relates to a pipeline leakage test set and method. The test set comprises a power system, a leakage unit, a valve, a temperature meter, a volume flowmeter and a pressure meter. The power system is connected with the leakage unit through a pipeline. Two ends of the leakage unit are respectively connected with the valve, the temperature meter, the pressure meter and the volume flowmeter. Calculated and metered values of gas or liquid stable leakage rates are compared to obtain a correcting model of a gas or liquid stable leakage rate equation; the model is applicable to the research on features and regulations of stable and dynamic leakage of gas, liquid or gas-liquid mixture in pipes or storage tanks under various different leakage conditions; the theoretical basis for the daily safety maintenance of long-distance pipelines and the emergency relief and investigation of leakage accidents is provided.

Description

technical field [0001] The invention relates to the fields of petroleum and chemical safety engineering, in particular to a pipeline leakage experimental device and an experimental method, which are suitable for studying the characteristics and laws of pipeline and storage tank leakage. Background technique [0002] Pipeline transportation has the advantages of low cost, stable supply and high safety, and has been widely used in the petrochemical industry. Due to the long service life of some pipelines and the frequent impact of road construction, vehicle rolling, electrochemical corrosion, geological subsidence and other reasons, long-distance oil and gas pipeline leakage accidents occur from time to time. In addition, oil and gas are flammable, explosive and other dangerous characteristics. Once leaked, it is very easy to cause vicious events such as fire and explosion, which poses a great threat to public safety. [0003] At present, the research on the characteristics a...
