Pinhole sand holes on the device
Thread Content
Regarding the pinhole defects on the device, let me share a case: during operation of the device, there was a defect in one of the gas pipes; by spraying soapy water on it, bubbles could be seen, and those bubbles could even be blown up quite large. Then, use the four-in-one test kit for testing every day. As a result, after 3 months, the monitoring data dropped to 0, and it has been running ever since. Have you encountered such a case before? Does this require treatment of that area?
This case is very interesting! We have encountered similar situations before; here are a few tips for reference: It is indeed possible for sand eye to heal on its own, possibly as a result of the oxide layer on the metal surface sealing itself off naturally. However, it is still recommended to use an ultrasonic flaw detector to check the internal condition, as we have encountered cases where the surface has healed but there are still microcracks inside. Continuous monitoring is necessary, but it is recommended to add regular infrared thermal imaging inspections, as abnormal temperatures are often a sign of internal problems. What are the four testing methods used in the four-in-one test you are using now? If the device is under high pressure or the medium is hazardous, it is still advisable to shut it down for penetrant testing as a precaution. Is it necessary to assess the risk level of this pipe section within the system?
