Device leak point management
Thread Content
The packing of a DN20 drain valve on the sewage oil line in the tank area is leaking oil (or an oil-water mixture); drops occur every few minutes. Tightening the packing several times had no effect, and the valve is too small to allow for replacement of the packing. The sewage oil line is still in use – how should such leaks be dealt with?
Just act like you can’t see it; others can still see it, and **it’s not good if the inspectors see it. . There is no significant impact for now, and it’s not possible to stop the processing; therefore, a sign can be placed to indicate this situation, the task should be included in the maintenance schedule, and the leaked material should be collected to prevent it from spilling on the ground.
If the pressure isn’t high, there should be some sealant or similar available to seal the leaks
I really can’t stop it, so I have to use a stopcock; I’ll replace the valve entirely when it’s convenient to do so.
1. Add mandatory scheduled inspection items； 2. Add to the parking maintenance plan ； 3. Labeling, nature of the item, procedures for dealing with leaks that spread, and procedures for dealing with situations where no further leaks occur ； 4. Provide training for all on-site workers ； 5. Report to the safety and environmental department.
Try the sealant first to deal with it temporarily; address it properly once production stops
On the premise that it does not affect safe production, temporary measures should be taken first, such as using containers to collect the substances, cleaning them regularly, installing signs, keeping records, and replacing the valves after the operation is stopped. Issues affecting safe production must be addressed through emergency shutdown and rectification. :)
