I would like to ask everyone: can a leak in a liquid nitrogen pipeline be sealed while the system is under pressure?

Can a leak in a liquid nitrogen pipeline flange be sealed under pressure? If possible, what method would be used?
Seal the leak using pipe clamps or steel straps!
It depends on the specific situation; there are good ways for online use. If pressure relief is possible, that is the safest approach; welding is the best option.
Pressure-based leak sealing has its limits of application; it is suitable for ordinary oil pipelines. Liquid nitrogen, however, requires low-temperature conditions, and pressure-based operations are not appropriate for it, whether in terms of personnel, the environment, construction equipment, or pipeline systems.
Thank you. The pressure at the leaking flange is 4 kilograms. Using a steel strip can temporarily stop the leak, and it would be more secure to seal it with glue using clamps from the outside.
Create a fixture, which can then be used to inject sealant to stop leaks
