The sealant used for plugging leaks under pressure remains imperfect after being in use for a period of time (half a year). What are better and more durable solutions?

This is the drawback of sealing leaks under pressure; it’s already good if the seal holds for half a year. Here, leaks usually occur after two or three months, and we resolve them by applying sealant.

1. Sealing leaks in container pipelines under pressure is a type of on-site emergency repair method, primarily used in situations where it is not possible to stop the operation of the equipment for maintenance (or to perform welding work), or when stopping the operation would result in significant losses. It can be considered a temporary emergency measure, and should not be used over a long period of time； Therefore, the area where pressure-based leak sealing was used should have regular maintenance carried out as soon as possible, to remove the sealant devices used for stopping the leak. 2. Sealing adhesives used for plugging leaks under pressure have a certain shelf life even when not in use and are simply stored in a warehouse; generally, their shelf life at room temperature is 3 to 6 months. For reference!

There are too many types of sealants available; you can check the product instructions to choose a more suitable type, or you can refer to methods for sealing leaks under pressure to see if it’s possible to stop the leak without using a sealant

Let me share my views. In industrial installations, the use of pressure-based leak sealing methods indicates that the equipment or pipelines cannot be taken offline for regular maintenance, and therefore conventional welding or other standard repair techniques cannot be used to fix the leaks. As a temporary solution, pressure-based leak sealing is employed. It’s certain that the sealant used in these methods has a limited shelf life. Moreover, such sealants are affected by frequent fluctuations in temperature and pressure. In industrial settings, we often encounter this problem: in some areas where sealant is applied, high temperatures and pressures exist, but no issues arise for a long time; repairs are only necessary when the sealant reaches the end of its useful life. In other areas, although the temperatures and pressures are not high, leaks occur frequently, which suggests that there may be constant changes in those conditions
