Embodiment Construction

[0063] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0064] Based on the acoustic emission detection technology, on the premise of the gas pipeline acoustic emission detection test and field application, the experience and achievements of the laboratory and the on-line leakage detection of the gas pipeline are summarized, and the method of the present invention is proposed.

[0065] The invention provides an on-line detection and positioning method for gas pipeline leakage. The detection equipment is directly installed on the gas pipeline production line, and the acoustic emission leakage detection technology is used to detect and locate the leakage in real time through real-time detection and real-time feedback information.

[0066] Leakage detection of gas pipelines can be carried out under the conditions of production and operation, with limited excavation or no excavation of pipelines. Limited excavation me...

Abstract

The invention discloses an on-line detection and location method for gas pipeline leakage and a device thereof. Based on acoustic emission detection technology, this method summarizes the experience and results of laboratory tests and on-site detection of gas pipeline leakage, and mainly describes in detail from the aspects of detection preparation, detection procedures, detection result analysis, and verification. Proposed new specific technical details of gas pipeline leakage detection and location, supplemented and perfected the deficiencies in the application of domestic gas pipeline leakage detection technology, promoted the improvement of detection and monitoring methods of urban gas pipeline network, and found urban gas pipeline network leakage in time It is of positive significance to prevent hidden dangers, prevent them before they happen, effectively prevent major urban fires and explosion risks, and accelerate the transformation of related technical achievements and their wide application in engineering practice.

Description

technical field [0001] The invention relates to an on-line detection and location method for gas pipeline leakage and a device thereof, belonging to the field of oil and gas storage and transportation risk control. Background technique [0002] Since the founding of the People's Republic of China, especially after the reform and opening up, my country's urban gas industry has developed rapidly, the construction of gas pipeline networks has been accelerated, and the gas supply capacity has been continuously enhanced, which has promoted the development of urban economy and society. By 2006, the length of urban gas pipelines across the country had reached 189,500 kilometers, including 50,500 kilometers of artificial gas, 17,500 kilometers of liquefied petroleum gas, and 121,500 kilometers of natural gas. [0003] Due to the limitations of the pipeline technology and pipe materials used at that time, some cities adopted gray cast iron pipelines and backward pipe connection metho...
