腐蚀是导致管道完整性损害的威胁之一。虽然管道通常被施以防腐层和阴极保护，但是所谓的潮湿腐蚀仍旧影响管道并导致管道壁厚减薄。腐蚀的类型多种多样，部分特别明显的现象表现为点腐蚀或者沟槽腐蚀。金属组件上由于被选择性或者有腐蚀介质而发生的腐蚀比均匀腐蚀的速度快的多。

点腐蚀特征为其腐蚀深度增长速率远大于腐蚀表面积增长速率。特别是在其未达到关键尺寸或者可能导致泄露或者破裂时必须安排进行检测。

One threat to the integrity of a pipe wall is the occurrence of corrosion. Although usually protected by coating and cathodic protection, so-called wet corrosion can affect a steel pipe and lead to wall thinning. Various forms of corrosion can be experienced and some of the more serious manifestations are pitting and channeling corrosion (i.e. chaining of pittings). Here, the metal of the pipe is attacked either selectively and/or uniformly by the corrosive medium which can lead to a component failure much more rapidly than average corrosion rates might infer.

Pittings are characterized by a strong growth in depth as compared to the surface area and therefore must be detected before reaching a critical size and causing a leak or possibly rupture.

在管壁的裂纹和其他材料的分离可能严重影响管线的完整性。不同类型的裂纹都可以被检测出来，例如疲劳裂纹是由于循环载荷产生的，或应力腐蚀裂纹是由于腐蚀环境，临界应力以及易感材料产生的。

Cracks and other types of material separations in the pipewall can have a serious effect on the integrity of a pipeline. Different types of cracks can be detected, for instance fatigue cracks due to an applied cyclic loading or stress corrosion cracking (SCC) due to a corrosive environment, critical stress and susceptible material.

裂纹和类似裂纹缺陷可能出现在制管，修建管线或管线服役期间。不考虑其来源，要在裂纹达到特定材料的临界尺寸而致使管线故障之前检测并确定其位置。真正的裂纹检测工具，如LineExplorer UC系列，提供了非常有效的管道内或焊缝区的裂纹检测，尺寸测量和定位手段。UC超声波裂纹检测器的标准配置主要用于检测轴向裂纹缺陷。Cracks and crack-like features can appear during manufacturing of the pipe, construction of the pipeline or during operational life. Irrespective of its origin, it is of great importance to detect and locate a crack before it can grow to reach a material-specific critical size after which the pipeline will fail. True crack inspection tools, such as the LineExplorer UC range, provide an effective means to detect, size and locate cracks in the pipe wall or the weld zone. The standard configuration of the LineExplorer UC is primarily designed for cracks orientated in an axial direction (along the pipe axis).

UC超声波裂纹检测器特别适用于液体输送管道，如原油或成品油管道，因为液体可以作为超声波的耦合介质。也可以通过施加一段液体耦合介质（油、水等）在气体输送管道内运行。

The LineExplorer UC operates in a liquid environment such as crude oil or product pipelines. The liquid serves as the coupling medium for the ultrasonic pulses. The tools can also be used in a gas pipeline, by applying a suitable liquid batch.

裂纹检测是探头通过耦合介质发射到管壁上45°的剪切波，遇到内外裂纹会反射回来并被探头接收。由于其高等级的可靠度和精确度，超声波裂纹检测是业界公认的高分辨率无损检测技术。技术原理见图。

裂纹检测技术原理 LineExplorer UC:Operating Principle

Crack inspection is performed in the pulse-echo mode using shear waves with a propagation angle of approx. 45° in the pipe wall. Due to its reliability and accuracy, this technique is well known in non-destructive testing as a standard technique of ultrasonic crack inspection. The principle used is illustrated in Figure 3.

LineExplorer UCc:Special Configuration for Circumferential CracksThe LineExplorer UCc is a special configuration of the crack detection tool offered by NDT Systems & Services. It consists of the modular LineExplorer UC and a specially designed sensor carrier,where the ultrasound transducers are arranged in axial direction in order to detect and size circumferential cracks and crack-like features. The tool and the associated data analysis software are optimized for the detection and sizing of flaws in and around the girth weld of a pipeline. This special configuration also includes all other technical advantages of the LineExplorer UC fleet.

Usually, the major stress acting in the wall of a pipeline are hoop stresses induced by the internal pressure present during operation. For this reason cracks that might potentially appear in the steel wall are usually oriented in an axial direction, along the length of the line. However, it is possible that the pipeline may be subject to additional stress, such as bending stress due to subsidence (e.g. offshore or in mining areas). Resulting axial stresses in the pipe wall can act as a driving force for circumferentially orientated cracks, especially in the vicinity of the girth weld and the associated heat affected zone.

环向裂纹 UCc LineExplorerUCc环向裂纹检测器

Circumferential Cracks

管线由于受到内部压力而形成的主要应力方向沿管道环向方向。因此，管线上的裂纹一般都是沿着管道轴线方向分布。

随着我国经济社会基础设施的不断发展，土地资源越来越紧张，各种电压等级的高压输电线与天然气管道近距离铺设或者交叉现象越来越多。由于管线与高压输电线近距离铺设容易导致管线交流杂散电流腐蚀。另一方面，随着地铁建设工程的不断上马，由地铁杂散电流造成的管线腐蚀事故也经常发生。As the domestic economic and social infrastructure continues to develop, land resources are increasingly strained, meanwhile, numbers of close laid or crossed various voltage levels of high voltage transmission lines and gas pipelines are rising. On the one hand, the close laying of pipelines and high-voltage power lines easily lead to AC stray current corrosion of pipelines. On the other hand, with the metro construction projects continue to be launched, pipeline corrosion accidents caused by the metro stray current often occur.

盛隆石油管检测技术有限公司专业做管线交/直流杂散电流检测相关工程，包括杂散电流干扰源检测及评级、杂散电流排流保护工程等。公司对多个受杂散电流干扰管线项目进行了杂散电流检测与排流保护，例如受到上海地铁1号线、7号线、11号线的杂散电流干扰的多条天然气高压管线等。管线经过杂散电流排流后，管线受到的杂散电流干扰水平显著降低，有效提高了管线运行的安全性。
