Abstract

The invention provides an on-line monitoring method for service extension deformation of a non-metal gathering pipeline. By the on-line monitoring method, the problems that an existing monitoring method cannot be used for monitoring axial extension large dependent variable, is high in monitoring cost and complicated in device structure and real-time monitoring and large-range promotion cannot be achieved are solved. The method comprises the following steps of 1) processing axial deformation on-line monitoring device of the non-metal gathering pipeline, wherein the device comprises an axial deformation sensor base, an axial deformation sensor protection shell and a bending sensor, the axial deformation sensor base and the axial deformation sensor protection shell are buckled to form a hollow cavity and are matched in a sliding way, the bending sensor is bent and placed in the hollow cavity, and a wire groove is formed in the axial deformation sensor base or the protection shell; 2) acquiring an initial state calibration value of the pipeline; 3) acquiring a resistant value-sliding distance corresponding table; 4) fixing the axial deformation on-line monitoring device of the non-metal gathering pipeline; 5) installing the non-metal gathering pipeline; and 6) acquiring the axial deformation quantity of the non-metal gathering pipeline.

Description

technical field [0001] The invention relates to a monitoring technology for deformation of non-metallic gathering and transportation pipelines, in particular to a method for on-line monitoring of service elongation and deformation of non-metallic gathering and transportation pipelines. Background technique [0002] Due to the advantages of large transportation volume, stability and continuity, low cost, less land occupation, and convenient maintenance, pipeline transportation is the main mode of transportation for natural gas, crude oil, refined oil and other products in the modern energy industry. Since oil, gas and other multi-phase media transported by oil and gas gathering and transportation pipelines are flammable and explosive, and often pass through densely populated areas, once an accident occurs, it will cause huge personnel, economic losses and environmental pollution. Therefore, it is necessary to The monitoring of gathering and transportation pipelines, in partic...
