Settings for startup purging and gas tightness testing of the device
Thread Content
Each time the unit is started up, a large amount of unit air and nitrogen are required for purging and airtightness testing. How is this configured in the projects you are working on? Participation is rewarded.
The quantities are determined based on the original design, and the production organization department coordinates their allocation.
It is matched according to the start-up time and plant scale.
This question made me think for a long time; the gas sealing is carried out before starting the device, and it’s done in a systematic manner, step by step
After the project is installed, compressed air is required to perform a pressure test for leak detection. Alternatively, nitrogen displacement can be used; based on the principle of proximity, contact the workshop to obtain it from there.
For a factory starting up for the first time, purging with air is carried out; after normal maintenance, purging is generally not required. Afterwards, nitrogen is used for airtightness testing, and the pressure level of nitrogen varies depending on the installation, with the final airtightness pressure being determined by the specific conditions available. Then the hydrogen is airtight.
How is a large amount of nitrogen or plant air supplied?
