Description
Technical field
The utility model is related to pipeline drift diameter diameter measurer technical field, is a kind of high accuracy pipeline drift diameter diameter measurer.
Background technology
In work progress and during coming into operation, factors can cause pipeline to be damaged to oil and gas pipes, will affect defeated
Send the safe handling of pipeline.As mechanical impact when lifting, transport, descending pipelines into ditch, the bottom of trench heavily fortified point top pressure of stone, thermoplastic deformation, the
The reasons such as tripartite's breakage in installation, the deformation for often making pipeline generation different degrees of, such as canal depression, ovalizing deflection, bending and sinking,
Pipeline breaking may be caused where serious, this brings potential safety hazard to conduit running, or even causes to stop production so that bringing economy
Loss.Drift diameter detector is by operation in pipeline, measurement internal diameter of the pipeline data, tells curved from testing result data
Head, valve, girth joint, and pipeline exist depression, ovality change etc. geometry deformation defect；Relevant position is measured simultaneously,
Buried pipeline actual state is grasped, determines that pipeline needs the part of transformation, exclude hidden danger in time.
