Flange leakage issue caused by pressure buildup in the tank area
Thread Content
Summer has arrived, and pressure buildup in the tank area has caused flange leaks. Later, the management developed a plan to release pressure at regular intervals, but oil leakage still occurred frequently. During the last shift, we experienced severe oil leakage; five or six flanges on the pipelines between the two tanks were leaking at the same time, and a large amount of oil sprayed out and turned into mist. Fortunately, no fire broke out. Post-analysis suggested that it was caused by opening the valve too quickly. Which expert can share relevant materials on this topic?
Reply to 1# MiaoMiaoYue: A solution is to keep a valve open along with a storage tank within a certain process flow in order to prevent pressure buildup accidents, but this approach increases the workload； It is advisable to install safety valves on the pipeline, with these valves releasing pressure into the storage tank; this will result in a slight increase in investment
Installing a slightly opening safety valve on the pipeline leading into the tank, with its outlet connected to the large tank, will solve the problem
Leave one valve on the pipeline slightly open
During the summer, it is essential to pay attention to sealing and pressurization; try to keep the pipelines that are not in use or are used intermittently with one end open to allow pressure to be released. If this cannot be done, then establish rules for releasing pressure periodically!
A pressure relief point has been confirmed on one of the pipelines
