When encountering a leak that cannot be fixed, should one choose to stop operations or seal the leak while the system is still under pressure?

How do you choose your devices?
Your question isn’t clear enough; pressure, temperature, material, and medium need to be specified in order to make a judgment
We can keep going as long as possible; the cost of stopping is too high
If it’s possible to seal the leak while the system is under pressure, that’s of course the preferred option; if that’s not feasible, then it’s necessary to stop operations and deal with the issue properly
For process media, we generally choose to shut down the system. Other media might consider pressure-based leak sealing, but in practice we have used clamps to seal leaks in steam systems.
Parking management definitely incurs high costs and significant expenses. But safety is the most important thing; it doesn’t matter if it’s related to public utilities, but for other types of media, it depends on the circumstances. But always remember, safety first
If it can seal leaks under pressure, then it definitely handles the task under pressure. Maintain production operations first. Waiting for the parking maintenance to be thoroughly completed
Consider the process conditions: will leaving it untreated have any impact on safety, the environment, or pose any potential risks? If there is an impact, then consider whether continuous production is feasible, as well as comparing the cost of shutting down the plant with the cost of sealing leaks under pressure. When asking questions, remember to specify the exact process conditions and relevant information.
It depends on the actual situation on site; each case needs to be analyzed individually. We have carried out leak sealing while the system was still under pressure, as well as shutting down a single system
First of all, I personally disagree with carrying out leak sealing under pressure, as this process is actually a form of illegal operation; there are many uncertainties involved, and if an accident occurs during the sealing process, the consequences could be disastrous. It is now **explicitly prohibited to carry out pressure-based leak sealing operations. On the other hand, if a complete shutdown or reduction in production is required just because of a leak in one flange, from the perspective of corporate profitability, it is indeed not worth it.
The pressure-containing leak sealing technique is an online repair procedure carried out without damaging the existing process pipelines and flanges. Most leaks can be addressed using the injection sealing method and other approaches. For plugging leaks under pressure, it is still necessary to seek out professional companies with experienced staff who have a high level of safety awareness, as well as procedural support and oversight throughout the operation. It is relatively safe and indispensable in the energy industry. Tianshi Sealing, Wang Bin, 022-25990436. A state-owned enterprise that has been restructured; specializes in safety solutions.
