What procedures are required for changing the medium in a pressure vessel?
Thread Content
There is an existing renovation project that involves reusing several pressure vessels from this facility; the working medium needs to be changed, and these pressure vessels currently have registration certificates. I asked the approval authority, and they said they have not handled this type of business. Please help me find a way around this
Approval from the original design unit is required, along with a written certification document.
This falls under the category of \"modification\" and should be handled in accordance with Article 5.2 of TSG21-2016 \"Safety Technical Inspection Regulations for Fixed Pressure Vessels\"；

First, a qualified inspection agency conducts a comprehensive inspection and testing of the container and issues an inspection report. The original design agency then uses this inspection report, along with the original design drawings and completion documents, to develop a design for modifying the container, proposing design suggestions or modification plans. These are submitted to the supervisory inspection department for approval, and modifications are carried out once approval is granted.
It falls under the category of pressure vessel modifications; a modification plan must be prepared, and written approval from the original design firm or a design firm with the appropriate capabilities is required.
The medium is an important parameter of the container; procedures are required if it needs to be changed later
Go through the modification process. If it’s turning air into nitrogen, there’s no need to go to such lengths; if it’s a dangerous process, just buy a new one. After all, safety first.
