12 kilograms of steam have leaked – how should this be dealt with? ?

In our facility, a small crack appeared in the anti-condensation pipe of a 12-kilogram steam pipeline; right next to it there is a valve, and as a result, a large amount of steam leaked out, producing a very loud noise that could be heard even dozens of kilometers away. We don’t know how to deal with this situation. If any of you colleagues have experienced something similar, please share some ideas. Thank you! !
It depends; the pipeline where the leak occurred was stopped using American methods! The valves on the main pipeline can be opened fully to reduce the amount of steam in the anti-condensation pipeline; thereafter, plugs can be used to seal the leaks. The workers must wear thermal protective clothing and pay close attention to safety.
Stop and fix it; otherwise it’s not safe.
If it is not possible to carry out work on the steam main, stop feeding material and operate the separation system in single-tower mode (partial shutdown) to repair the steam pipeline as soon as possible and restore production!
Short stop, pressure relief, leak sealing \ patch welding.
If it is not possible to shut down the unit, it is recommended to use drainage to reduce pressure, and apply glue through plugs to seal the leaks
If it can’t stop, you can wrap it in a box; if it’s too close to the valve, you can wrap the valves together as well.
Sealing a steam pipeline leak with a box is extremely dangerous; the box could explode, so it is not recommended to use this method.
I’m the poster of this thread. What everyone has mentioned is about releasing steam from within the equipment; for example, some people suggest opening the main valves fully or using plugs to seal leaks – all of these seem to be viable options. However, in our case, it’s the anti-condensation pipeline on the 12-kilogram pipeline system that has cracked. If this isn’t dealt with properly, it could affect the steam supply to other equipment ?
The impacts also need to be addressed; ensure good coordination in the work. Can such a large breach be delayed?
The only aspect that does not affect production is the packaging process. We encountered an issue where severe corrosion occurred due to exposure to air; when trying to handle it, excessive force was applied and the container fell apart. The pressure at that time was 1.0 MPa. In order to address this, all necessary protective measures were taken, and a DN100 large valve was used for the packaging process.
