The process outlines how to determine the equipment operating pressure under purge conditions
Thread Content
There is a device that handles highly hazardous media. Its operating pressure is -0.88, the operating temperature is 60°C, and its volume is 3000 L. The design pressure is set at -0.1. This device cannot be classified into any specific category. The process requires a purging pressure of 0.3 MPa. There are several issues that are not clear; I would appreciate it if someone could provide guidance: 1. Is it necessary to assess the impact of 0.3 MPa on the strength of the device? 2. Should the purging pressure be considered as the operating pressure, thereby affecting the classification of the device?
I think it should be accounted for, but the classification doesn’t need to be based on this. Just wait for the correct answer downstairs.
The strength of the equipment under a pressure of 0.3 MPa should be verified; classification does not require consideration of purging conditions.
No need for categorization; separate cleaning plans can be developed for items that don’t fit into any category – this has no impact
