近几年来，随着石化装置运行或大修周期的延长，生产规模不断扩大，复杂的工艺环境对检测产品提出了更高的要求。近几年来，随着工业内窥镜生产制造技术的发展，内窥镜检测已逐渐成为一种检测技术，通过工业内窥镜检测，工作人员可准确判断压力容器及管道焊缝缺陷的大小及特点然后进行内窥镜设备维修。工作人员通过定期检测就能及时发现使用过程有无新生缺陷，从而能及时提醒工作人员对设备进行维修，达到设备及人员安全的目的。
In recent years, with the extension of petrochemical plant operation or overhaul cycle, the scale of production has been expanding, and the complex process environment has put forward higher requirements for testing products. In recent years, with the development of the manufacturing technology of industrial endoscope, endoscope detection has gradually become a detection technology, workers can accurately judge the size and characteristics of pressure vessels and pipeline weld defects. Through regular testing, the staff can find out in time whether there are new defects in the use process, so that they can timely remind the staff to carry out maintenance of the equipment to achieve the purpose of equipment and personnel safety.
