Description

technical field [0001] The invention relates to the technical field of pipeline diameter measuring devices, and relates to a high-precision pipeline diameter measuring device and an air-inflating speed-regulating method thereof. Background technique [0002] During the construction and use of oil and gas pipelines, many factors will cause pipeline damage, which will affect the safe use of pipelines. Such as hoisting, transportation, mechanical impact when the pipeline goes down the ditch, the top pressure of the rock at the bottom of the ditch, thermoplastic deformation, third-party construction damage, etc., often cause the pipeline to deform to varying degrees, such as pipeline depression, elliptical deformation, bending and Subsidence, in serious cases, may cause pipeline rupture, which brings safety hazards to pipeline operation, and even causes economic losses due to production stoppage. The diameter detector operates in the pipeline, measures the inner diameter data o...
