For a plant that has been shut down for over a year, does it need to be pressurized again before restarting the equipment?
Thread Content
We have a set of chemical processing equipment here; over a year ago, work was carried out on maintaining the equipment and conducting pressure tests, as well as testing the transportation by water, but operations were not started at that time for various reasons. More than a year has passed now; if work resumes, will it be necessary to remake samples of the equipment? Is there any regulatory basis? Thank you to all the teachers for helping to answer the questions
I’m not really sure about the regulations, but I remember that once a set of equipment here stopped working for three months; when work resumed, everything had to be done over again. When something goes wrong, if you haven’t done your job properly, it’s definitely your fault!
It seems there are no similar regulations, but since it has been shut down for such a long time, the procedures usually follow those for new installations; in fact, the requirements are even stricter than those for new devices
It is not known what industry the device in question belongs to; generally, pressure-bearing equipment are pressure vessels, and it should be handled in accordance with the requirements of \"TSG 08-2017 Rules for the Use and Management of Special Equipment\" and \"TSG 21-2016 Safety Technical Inspection Regulations for Fixed Pressure Vessels\". The regulations specify the requirements for dealing with special equipment that has been out of use for more than one year (Section 3.9 of TSG 08-2017, Rules for the Use and Management of Special Equipment); the supervision procedures outline the relevant inspection and testing requirements. Pressure pipelines must also be handled in accordance with the relevant supervision procedures, and pressure testing is a required procedure.
Follow the established procedures for the testing and commissioning of chemical processing units once again.
Operations must be carried out in accordance with the specifications for special equipment, and permission is granted only after passing the inspections
