Absurd! The propane horizontal tank manufactured in 1965 with a pressure of 225 PSI at 100°F needs to have its pressure increased to 260 PSI at 130°F.

Absurd! Is it possible to upgrade the propane horizontal storage tank, which was manufactured in 1965 with a pressure rating of 225 PSI at 100°F, to a pressure rating of 260 PSI at 130°F for alternative uses? Inner diameter: 134\" Total length: 112' Material: SA212-B Volume: 11620 ft3 Wall thickness: 0.964\" as measured currently Head thickness: 0.544\" as measured currently What are the necessary steps to follow? Thank you first!
Was it sent correctly? Is it confirmed to be a container from 1965? Discard directly!
The equipment must first be inspected in accordance with the relevant provisions of the Fixed Capacity Regulations; if its safety level is grade 5, it cannot be used any longer.
All the above information is correct; there are no other issues.
The Quality Supervision Bureau and the Special Inspection Institute will likely ask you to provide reasons for either modifying it or continuing to use it! ;P
The material is completely different from what it is now; it’s very difficult to get it to pass the inspection if one wants to use it again
Clause 7.1.7 of these regulations: Pressure vessels that have reached their design service life. For pressure vessels that have reached their design service life (those for which no design service life is specified, but which have been in use for more than 20 years are considered to have reached their design service life), if they are to be continued in use, the user entity shall commission a special equipment inspection agency with the appropriate qualifications to conduct inspections in accordance with the relevant provisions for regular inspections; if necessary, a safety assessment (usefulness evaluation) shall be carried out in line with the requirements of Clause 8.8 of these regulations. Only after approval by the person in charge of the user entity can the change in the use registration certificate be processed, allowing the vessel to continue to be used. You are referring to an imported piece of equipment from 50 years ago; to continue using it, it is necessary to increase the design temperature and pressure. Any change to the operating conditions must be approved by the original design unit, while extended use requires a certification issued by a testing institution. Question: 1 The original design documents are no longer valid, and the original design firm cannot be found. 2 No testing agency will be willing to test a pressure vessel that is 50 years old. The original poster already said it’s absurd – why go through with it then?
