Failure analysis of the filter level gauge lead pipe in high sulphur-containing natural gas natural gas purification equipment
The problem of the failure of the raw gas filter in the desulfurization unit of a large purification plant are introduced.The chemical composition,metallographic structure,and fracture morphology of the straight pipe section and welding flange of the filter level gauge are analyzed to explore the main reasons for the failure.The results indicate that the reason for the failure of the feed gas filter is that the material of the filter does not meet the requirements,and long-term exposure to low temperature and acidic media environment leads to the chloride stress corrosion failure of the feed gas filter.Accurately understanding the causes of equipment failure and taking targeted protective measures is of great significance for ensuring the long-term safe operation of the device.
