Technical field
This utility model relates to a kind of detecting system, the high-speed detection system of a kind of petroleum pipeline.
Background technology
At present, petroleum pipeline is detected by commonly used hydrostatic(al) process.Continue hydrostatic test and can only detect the minority defect such as through hole and screw thread damage.But petroleum pipeline is wounded by the inwall acid and alkali corrosion of pipeline, crackle and heating cable discharge and the common deficiency such as super mill scuffing that sucker rod is serious to inboard wall of tube body cannot detect.What the petroleum pipeline with defect had endangers especially severe to producing well, and have has an effect on continuation safe handling.Therefore, identify these defect types, reject and have the petroleum pipeline of harm to have important practical significance.
So a kind of the most quickly petroleum pipeline detecting system is arisen at the historic moment, can detect that the inside and outside wall of body and internal all kinds of defect.
Utility model content
The purpose of this utility model is to provide the high-speed detection system of a kind of petroleum pipeline, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of high-speed detection system of petroleum pipeline, including key station 8 and main survey device, key station 8 connects main survey device, described key station 8 major control oil-sludge treatment device, transmit line, automatic positioning equipment, sorting unit, Classifcation of flaws program display processor, fine defects signal processor, large area flaw indication processor forms, described main survey device is by excitation supply 7, detection coil 2, linear transducer array 3 forms, described excitation supply 7 communication with detection coil 2, and be connected with pipe under test 1, described detection coil 2 connects linear transducer array 3, guarantee that pipe under test 1 is magnetized by the abundant of " Helmholtz " magnetizing assembly at detection zone, owing to large area defect 5 produces stray field 6 inside detection coil 2, form flaw indication, key station 8 and main survey device can wirelessly transmitting datas simultaneously.
As further program of the utility model: described main survey device is seamless is close to pipe under test 1 surface.
As further program of the utility model: described detection coil 2 uses stagewise magnetic susceptibility transmitter group.
As further program of the utility model: described linear transducer array 3 picks up the vertical Wavelet Component of material surface, fully magnetizes.
As further program of the utility model: described sorting unit has the defect parameters model that magnanimity is easy to quickly identify.
