If a pressure vessel is used for a different purpose in the process, what procedures are required?
Thread Content
Pressure vessels experience changes in pipe connections and in their process applications, which in turn results in changes to the equipment identifiers and names; yet they remain pressure vessels. What procedures are required? Is it necessary to provide a notice for the modification and change the name and tag number?
Yes, it is necessary to go through the procedures for notifying about the modification of the pressure vessel, and change the equipment name and tag number to the corresponding new values. At the same time, safety assessments and tests are also required to ensure that the modified pressure vessels meet relevant safety standards and requirements. If necessary, approval from the relevant departments is also required. .
Provide a notice of the modification, and have a qualified entity carry out the relevant design work and prepare calculations for the strength.
To apply for a change in the usage registration, if it remains within the original approved parameters, there is no need to make any changes; if it exceeds those parameters, then no changes can be made either.
