摘要:

由于埋地油气管道敷设环境复杂,葡京线上注册:缺乏经济有效的检测手段确定管道的应力集中位置和应力集中程度,对此,该文提出一种磁力外检测方法。在中石油某长输输气干线利用非接触式磁力检测技术大范围排查应力集中管段,并给出油气管道应力集中程度的评价方法,然后对应力集中相对严重的管段开挖后进行接触式磁记忆检测定位应力集中具体部位,并利用X射线探伤技术对检测结果进行验证。试验结果表明:通过非接触式磁力检测和接触式磁记忆检测可以准确定位应力集中位置和评价应力集中程度,工程实际应用和X射线检测验证表明磁力外检测方法的可行性和有效性。磁力外检测技术与方法能够满足埋地油气管道应力检测的需要,具有良好的应用价值。

Abstract: There is no cost-effective testing methods to determine the location and degree of stress concentration due to the complex laying environment of buried pipelines. In view of this situation, an external magnetic detection method is proposed. In a long-distance gas transmission line of PetroChina, the non-contact magnetic detection technology is used to inspect the stress concentration pipe section, and the evaluation method of the stress concentration degree of the pipeline is given. Then, after the excavation of the pipe section with relatively serious stress concentration, the contact magnetic memory detection is carried out to locate the specific part of the stress concentration. The testing results were verified by X-ray inspection technology. The results show that the non-contact magnetic detection and contact magnetic memory detection can accurately locate the stress concentration position and evaluate the stress concentration. The practical application and X-ray inspection verification demonstrate the feasibility and effectiveness of the magnetic external detection method. The magnetic external detection technology and method can meet the needs of stress detection of buried oil and gas pipelines and has good application value.
