If the device is out of use for an extended period of time, with nitrogen filled inside at a pressure of over 1 kilogram, is it still necessary to submit it for inspection?

The plant is scheduled to be shut down for a long time, around two years. There are many tank systems, and it is planned to fill the plant with nitrogen at a pressure of about 1.5 kilograms per square centimeter! Additionally, it is planned to stop using the pressure vessel. I would like to ask whether it is acceptable to have more than 1 kilogram of nitrogen filled in the vessel if it is to be taken out of service

A nitrogen filling amount of over one kilogram on-site is acceptable

Nitrogen filling of over one kilogram should be sufficient, but it’s not clear whether another comprehensive inspection will be required before driving. Here, the quality supervision agency requires a thorough inspection of the pipes and containers before driving, even if the vehicle has been parked for a year.

I mean, since it’s already shut down and the service has been discontinued, is it acceptable to keep it under a load of over 1 kilogram? Although it’s under nitrogen protection, does the inspection authority approve this?

No problem, you also need to consider the leakage amount.

The amount of leakage was also significant; the chemical explosion in Rizhao, Shandong is a lesson we must learn from! One should not fail to follow the rules out of fear of trouble, as the consequences can be severe......................

You mean that since there is one and a half kilograms of nitrogen inside, it’s in use, so it cannot be declared as inactive, right?

Yes, long-term monitoring is necessary. Safety regulations are quite strict these days, so safety should come first

If it is disabled, report it as sealed. After going through the company’s internal procedures, it is still necessary to submit applications to security agencies and other relevant authorities. Then, you apply nitrogen sealing and pressure retention to each container and equipment based on the actual conditions.

It can be shut down directly; the materials should be removed. If nitrogen sealing is required, a slight positive pressure is sufficient~~
