Description
Technical field
The utility model is related to a kind of corrosion testing devices of Natural Gas High-pressure Pipeline.
Background technology
Natural gas line is typically to be embedded in underground, is used for delivery of fuel gas.During prolonged use, due to ground end
Wetness, and other corrosive elements often cause corrosivity to damage gas pipeline.Therefore, it is necessary to combustion gas
Pipeline carries out necessary maintenance.And detection operation is just extremely important, can accurately detect a certain position hair of gas pipeline
Corrosion damage is given birth to, it will be able to timely and effectively take countermeasure, avoid causing the industrial accidents such as gas leakage, improve combustion gas
The safety of pipeline.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of corrosion testing device of Natural Gas High-pressure Pipeline, detections
It is convenient, construction is simple, Detection accuracy height.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of corrosion testing device of Natural Gas High-pressure Pipeline, described device include the probe mounted in pressure piping outer surface
Ring, ultrasonic sensor is fixed on the probe ring, and there is erosion resistant coating, ultrasonic sensor to pass through connecting line on pressure piping surface
It is connect with detection host, metal is equipped between probe and pressure piping, band is installed, connecting line is equipped with connection box, connects box appearance
Face is equipped with waterproof membrane, and ultrasonic sensor is welded on probe ring, and multiple probe rings, ring of each popping one's head in are provided on pressure piping
On be equipped with ultrasonic sensor.
The corrosion layer thickness of the position of installation probe ring is less than 2.5mm on the pressure piping.
The metal installation band is magnesium cobalt band.
The length of the metal installation band is more than the axial length of probe ring.
The probe ring position is also located at shielding case, and will pop one's head in ring and ultrasonic sensor of the shielding case is contained in
It is interior.
The shielding case inner surface is equipped with moisture-proof adsorption layer.
The utility model is easy to detect, construction is simple, and Detection accuracy is high.
Description of the drawings
Attached drawing 1 is the utility model schematic front view.
Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
As shown in Fig. 1, the utility model discloses a kind of corrosion testing device of natural gas line, and described device includes
Probe ring 4 mounted in 1 outer surface of pressure piping is fixed with ultrasonic sensor 5 on the probe ring 4, and 1 surface of pressure piping has
Erosion resistant coating, ultrasonic sensor 5 are connect with detection host 7 by connecting line, pop one's head in and be equipped with metal between ring 4 and pressure piping 1
Band 2 is installed, connecting line is equipped with connection box 6, and 6 outer surface of connection box is equipped with waterproof membrane, and ultrasonic sensor 5 is welded on probe ring
On 4, it is provided with multiple probe rings on pressure piping 1, ultrasonic sensor is equipped on each ring of popping one's head in.
The corrosion layer thickness of the position of installation probe ring is less than 2.5mm on the pressure piping.When the thickness of corrosion layer is big
When 2.5mm, one section of erosion resistant coating, the length of about 30cm need to be removed.
The metal installation band is magnesium cobalt band.Metal installs axial length of the length more than probe ring of band, ensures probe
Ring will not be contacted with pressure piping.
4 position of probe ring is additionally provided with shielding case 2, and will pop one's head in ring 4 and ultrasonic sensor 5 of the shielding case 2 holds
In being contained in.2 inner surface of shielding case is equipped with moisture-proof adsorption layer 8.Pass through the shielding case so that ultrasonic sensor is not easy with probe ring
By external interference.Also utilize moisture-proof adsorption layer adsorbed moisture, it is ensured that the service life of ultrasonic sensor.
In addition, emitting low-frequency guided wave to high-voltage tube in the position of probe ring, low-frequency guided wave is propagated along pressure piping,
It is reflected when low-frequency guided wave encounters corrosion location 9, reflected low-frequency guided wave is detected and passed by ultrasonic sensor again
It is sent to detection host, detection host is analyzed according to preset analysis module, obtains the corrosion condition of pressure piping.Low frequency is led
Wave includes torsional wave and longitudinal wave, shear wave, generally all emits 2-3 kind guided waves.Propagate the frequency and material for depending on sound wave
Thickness, according to the shape of frequency variation and curve, to judge the size and orientation of defect.Directly detection is tied on detection host
Fruit shows.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
