Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a processing method of cathodic protection data according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
In this embodiment, the corrosion risk level of the pipeline is first obtained, and for the pipeline, although the cathodic protection system is provided, a certain corrosion risk still exists in the pipeline due to the change of external corrosion factors or the failure of the cathodic protection system.
In this embodiment, the corrosion risk level of the pipeline refers to the possibility of corrosion of the pipeline, and the specific evaluation mode may be set in a targeted manner according to requirements, for example, whether the pipeline has the possibility of corrosion is determined according to the cathodic protection potential of the pipeline, and specifically, the corrosion risk may be evaluated according to the change of the cathodic protection potential and the current density; for another example, the corrosion risk of the pipeline may be evaluated according to the adopted cathodic protection measures, for example, during the subsequent investigation of the pipeline, a previously undiscovered risk factor that may cause the corrosion of the pipeline is discovered, and when the cathodic protection system for the pipeline is designed previously, the risk of corrosion of the pipeline in the area is defined as a higher level without considering the risk factor. Furthermore, it is obvious that the risk of corrosion of the pipe can also be determined in other ways.
And 102, establishing a multi-dimensional corresponding relation based on the test piles.
In this embodiment, a multidimensional correspondence between the test pile and the cathodic protection system is further established, where the multidimensional correspondence specifically includes a correspondence between the test pile and equipment of the cathodic protection system, a correspondence between the test pile and a pipeline laying environment that affects a corrosion risk of a pipeline, a correspondence between the test pile and an operation parameter of the cathodic protection system, and a correspondence between the test pile and a pipeline corrosion analysis result.
The operation state of the cathodic protection system of the pipeline is reflected by the potential data measured by the test pile, so that the multidimensional corresponding relation between the test pile and the cathodic protection system is established on the basis of the test pile in the embodiment.
In this embodiment, the devices of the cathodic protection system mainly refer to devices related to the cathodic protection system, such as a potentiostat, an insulating joint, a steel sleeve, a sacrificial anode, a drainage ground bed, and the like, and the devices corresponding to abnormal data can be quickly judged by establishing a corresponding relationship between the test pile and the devices of the cathodic protection system.
The pipe laying environment affecting the corrosion risk of the pipe in the present embodiment refers to an external environment that may cause corrosion of the pipe, for example, if the target pipe intersects and runs in parallel with a third-party pipeline, or various pipe laying environments such as a high-voltage line tower, a high-speed rail, and a subway light rail exist near the target pipe. Taking the existence of the high-voltage line tower as an example, in the process of transmitting power by the high-voltage line tower in the form of alternating current, because the current direction changes constantly, the surrounding electromagnetic field is in the constantly changing process, induced current is generated on the pipeline, corrosion is generated, and the pipeline is also corroded due to the complex pipeline laying environment.
The corresponding relationship between the test piles and the operation parameters of the cathodic protection system in this embodiment mainly refers to the corresponding relationship between the test piles and the parameters measured by the test piles, in order to obtain the operation state of the cathodic protection system of a section of pipeline, a plurality of test piles are usually required to be arranged to continuously test the relevant parameters, and by establishing the corresponding relationship between the test piles and the operation parameters of the cathodic protection system, the variation condition of the operation parameters of the cathodic protection system can be further obtained according to the distribution condition of the test piles, and whether the cathodic protection system normally operates is further determined according to the variation rule of the operation parameters of the cathodic protection system.
The pipeline corrosion analysis results include special analysis results such as corrosion risk analysis results, protection potential analysis results, IR drop abnormality, and the like, and the reasons for possible corrosion at each position of the pipeline are different. For example, the test results of the two test piles both show that the cathodic protection potential changes by 50 mv, however, the corrosion risk of the pipeline corresponding to one test pile is mainly caused by the casing, the abnormality of the pipeline corresponding to the test pile may be caused by the overlap joint of the casing, and a subway is newly built near the pipeline corresponding to the other test pile, and the corrosion wind direction of the pipeline corresponding to the test pile may be corrosion caused by stray current generated by the subway.
In addition, the types of the corresponding test piles are different according to different corrosion risks, so that the corresponding relation between the test piles and the operation parameters of the cathodic protection system is further established in the embodiment to ensure that a correct pipeline corrosion analysis result can be obtained.
And 103, determining the corrosion factor of the target pipeline according to the multidimensional corresponding relation.
In this embodiment, a corrosion factor of the target pipeline is further determined according to the multidimensional correspondence, specifically, the target pipeline in this embodiment refers to a pipeline having a corrosion risk level greater than a preset threshold, for example, the corrosion risk is greater than 0, or the corrosion risk is greater than 10%, and since the target pipeline has a certain corrosion risk, after determining the corrosion factors that may cause the corrosion risks through the correspondence, the pipeline may be further repaired by a corresponding corrective measure, so as to reduce possible damage to the pipeline.
According to the embodiment of the invention, the multi-dimensional corresponding relation is established on the basis of the test pile, so that the corrosion factors influencing the pipeline corrosion can be accurately, conveniently and quickly determined according to the multi-dimensional corresponding relation.
Further, in another embodiment, the step 101 may include:
detecting the cathodic protection potential of the pipeline, and determining the DC corrosion risk level of the pipeline according to the cathodic protection potential;
judging whether the area where the pipeline is located has alternating current interference or not;
if the area where the pipeline is located does not have alternating current interference, determining the direct current corrosion risk level as the corrosion risk level of the pipeline;
if the area where the pipeline is located has alternating current interference, alternating current interference data of the pipeline are obtained, alternating current corrosion risk levels of the pipeline are obtained according to the alternating current interference data, and the higher one of the direct current corrosion risk levels and the alternating current corrosion risk levels is determined as the corrosion risk level of the pipeline.
In this embodiment, whether the cathodic protection potential reaches the standard is determined according to the cathodic protection potential of the pipeline. For example, in one embodiment, the corrosion risk of the pipe is classified into three levels, no risk, low risk, and high risk. Specifically, the cathodic protection potential is obtained by testing the power-off potential of the test piece, and if the cathodic protection potential is greater than-650 millivolts, the corrosion risk level of the pipeline is determined to be high risk; confirming that the cathodic protection system is at risk if the cathodic protection potential is less than or equal to-1150 millivolts; and when the cathodic protection potential is less than or equal to-1200 millivolts, the corrosion risk level of the pipeline is determined to be high risk; when the cathodic protection potential is less than 1200 mv, the corrosion risk rating of the pipe is confirmed to be low.
Further, if the cathodic protection potential is greater than-1150 mv and less than-850 mv, no corrosion risk of the pipe is confirmed. The corrosion risk level is further determined based on the resistivity of the soil if the cathodic protection potential is between-650 millivolts and-850 millivolts. For example, when the cathodic protection potential is greater than-750 mv, less than or equal to-650 mv, no risk of corrosion of the pipe is identified if the resistivity of the soil is not less than 1000 ohm-m; if the resistivity of the soil is less than 1000 ohm meters, and the cathodic protection potential is less than-700 millivolts, confirming that the corrosion risk grade of the pipeline is low risk; at a cathodic protection potential greater than or equal to-700 mv, the corrosion risk rating of the pipe is confirmed to be high.
Confirming no corrosion risk of the pipeline if the resistivity of the soil is not less than 100 ohm x m when the cathodic protection potential is more than-850 millivolt and less than or equal to-750 millivolt; if the resistivity of the soil is less than 100 ohm meters, and the cathodic protection potential is less than-800 millivolts, the corrosion risk grade of the pipeline is determined to be low risk; at a cathodic protection potential greater than or equal to-800 mv, the corrosion risk rating of the pipe is confirmed to be high.
Further, in this embodiment, the possible ac stray current interference is also considered, and in this embodiment, whether the ac stray current interference exists is determined by measuring ac interference data. The ac interference data in this embodiment includes an ac interference voltage, and in some cases, may also include an ac current density. For example, if the ac voltage is less than 4 volts, it may be inferred that there is no ac corrosion risk by the ac interference voltage, and if the ac interference voltage is greater than or equal to 4 volts, it may be further determined whether there is ac corrosion risk by combining the ac current density, for example, if the ac current density is greater than 100 amperes square meter, it may be determined that the ac corrosion risk level of the pipeline is high risk; confirming that the AC corrosion risk rating of the pipe is low if the AC current density is not greater than 100 amps square meter and the ratio is less than 30 amps square meter; if the ac current density is less than 30 amps square meter, no ac corrosion risk of the pipe is confirmed.
The ac interference of the pipeline may be determined by referring to other standards, for example, related standards of each country or region such as europe and the united states.
Whether the pipeline has the cathode protection risk or not is judged directly according to the cathode protection potential in the embodiment, whether the pipeline has the corrosion risk or not can be directly determined, and the pipeline with the corrosion risk can be rapidly determined, so that the analysis can be further carried out to determine the factors influencing the corrosion risk.
In yet another embodiment, the corrosion risk levels include a first level having a corrosion risk and a second level having no corrosion risk, and the step of determining a corrosion factor for the target pipe from the multi-dimensional correspondence includes:
acquiring historical data of a target test pile corresponding to a target pipeline with a first corrosion risk level and related data of a test pile associated with the target test pile;
and determining abnormal data in the measured cathodic protection system operating parameters of the target test pile based on the historical data and the related data;
determining target corrosion risk factors corresponding to the abnormal data according to the corresponding relation between the test pile and the pipeline corrosion analysis result;
and determining target equipment corresponding to the target corrosion risk factor in the associated equipment according to the corresponding relation between the test pile and the associated equipment, and determining the target equipment as the corrosion factor of the target pipeline.
In the present embodiment, the corrosion risk is classified into a first level and a second level, for example, the high risk level and the low risk level described above may be classified into the first level, and the risk-free level may be classified into the second level.
Further, historical data of a target test pile corresponding to a first-grade target pipeline with corrosion risk and related data of a test pile associated with the target test pile are obtained. In this embodiment, whether data measured by a target test pile is abnormal is determined by combining historical data of the target test pile and related data of a test pile associated with the target test pile, for example, if a measurement result of a certain test pile changes, the whole test data may change, for example, a cathode protection potential of a cathode protection system is adjusted, or a pipeline located beside a high-speed rail may be affected by a newly opened train, so that a measured cathode protection parameter changes to some extent.
And if the data measured by the target test pile is determined to be abnormal actually according to the historical data and the related data, further testing the corresponding relation between the pile and the pipeline corrosion analysis result, and determining the target corrosion risk factor corresponding to the abnormal data measured by the test pile. After the target corrosion risk factors are determined, the equipment with the abnormal condition is determined according to the corresponding relation between the test pile and the associated equipment, so that the factors causing the target pipeline corrosion risk and the equipment causing the risk are conveniently and quickly determined according to abnormal data.
In each embodiment, after the step of determining the risk factor of the target pipeline according to the multidimensional correspondence, the method further includes:
and generating a corresponding processing scheme according to the risk factors.
In this embodiment, a corresponding processing scheme is further generated according to the corrosion risk, so that the pipeline corrosion can be prevented from continuing.
Further, in a specific embodiment, the step of generating the corresponding processing scheme according to the risk factor includes:
if the risk factor is that the alternating current interference exists, generating an alternating current drainage scheme; or
If the risk factor is that the potentiostat is abnormal, generating a maintenance scheme of the potentiostat; or
