Background technique
Exist in natural gas line dry gas pipeline ponding and simultaneously containing be corrosive harmful matter component time can pipeline internal water accumulation place produce internal corrosion.But internal corrosion is one of reason causing pipe-line system serious aging, and it will cause pipe leakage, reduce structural strength, and the Security of the whole gas transmission system of serious threat, integrity and Economy.
For now, detecting to pipeline corrosion the main method used is: interior detection, pressure testing and directly evaluate.But because measurer not easily enters pipe interior, the internal corrosion of natural gas line is difficult to detect usually.The machinery of pipeline and geometric constraint make the application of on-line checkingi be hindered, and only have the pipeline of about 50% to detect by pigging online.Although Magnetic Flux Leakage Inspecting can be measured in detail to pipeline corrosion situation, also can internally give and accurate location the serious position of corrosive pipeline, all to stop the conveying to natural gas line during each detection in advance, stop producing, can not meet the requirement of rock gas interrupted transmission and continuous prodution, not only capital equipment is expensive, charge costs is large, and it is immature to there is domestic technique, detection time is long, operates the shortcomings such as very complicated.Pressure testing method requires that pipeline uses under stop status, and ultrasound and ray are taken pictures, and require excavate before testing and clear up pipe surface, all makes all fronts detect unrealistic.Therefore, to interior detection and the pipeline that can not interrupt carrying cannot be carried out, the direct evaluating method of choice for use internal corrosion (DG-ICDA) Integrity Assessment can be carried out.Direct evaluation has the features such as cost is low, easy enforcement, and the method is widely used in recent years.
Although the direct evaluating method of internal corrosion (ICDA) demonstrates the using value in pipeline industry, but the direct evaluating method of internal corrosion (ICDA) can not provide the accurate information about having the existence of corrosivity moisture, also cannot quantize the harm of corroding, more can not the ponding point existed in pipeline be positioned.
