When a pressure vessel is transported to another location for installation, does the local pressure vessel inspection agency have the authority to review the drawings?

I believe the local pressure vessel inspection authority has full regulatory power over such containers, including the review of drawings.

Of course there are! The local authority in charge of vessel inspections holds all regulatory powers over such containers, including the review of drawings; all completion documents must be approved before a use license can be issued! You can’t put it into use!

As I understand it, when the boiler inspection agency reviews the drawings, it checks whether there are any conflicts with relevant standards and regulations; as long as no errors that violate these standards and regulations are present, the local boiler inspection agency has no right to require the design team to make changes.

Yes, Article 58 of the Regulations on the Safety Supervision of Special Equipment stipulates that the departments responsible for the safety supervision and management of special equipment (inspection agencies) shall carry out safety inspections on entities that produce and use such equipment, as well as on inspection and testing institutions. They must keep records of the contents of each inspection, the problems identified, and the actions taken to address them. These records must be signed by the personnel carrying out the inspections and by the relevant officials from the entities being inspected, before being filed. If the relevant person in charge of the inspected unit refuses to sign, the special equipment safety inspectors shall record the situation.

Of course, one has this power. As long as it isn’t an original fault or a major error that renders the equipment unusable, they generally won’t raise any issues.

The place of manufacture conducts drawings review, while the place of installation does not. The containers have already been made – why review the designs anymore? ?

Has the boiler inspection agency changed the design requirements? The boiler inspection agency can only point out obvious errors in the diagram, such as clear mistakes in standard references or incorrect container classification. How could someone from the boiler inspection agency understand the design details?

Back to floor 7: The department responsible for the safety supervision and management of special equipment does not include the boiler inspection agencies. To this gentleman: Why can’t the people from boiler inspection agencies understand design aspects? If one can’t even understand design drawings, how can they carry out inspections of pressure vessels? Currently, in China, the manufacturing of pressure vessels is subject to local regulation. That is, it determines where the container is manufactured and which authority responsible for the supervision and management of special equipment oversees it (which is what people commonly refer to as on-site inspection by the local boiler inspection agency). In the case of the installation of large containers or complete sets of equipment, the local authorities responsible for supervising the safety of special equipment usually entrust the local inspection agency to carry out supervision and inspection of the on-site installation. If the equipment is delivered in sections and assembled on site, it is even more the responsibility of the local inspection agency to oversee such on-site installation. For the installation of small, individual pressure vessels, the inspection agency generally does not participate in the inspection process. In any case, if there are indeed issues with the design drawings, it is normal for the local inspection agency to point out those problems; however, it would be inappropriate for the inspection agency to impose its own design requirements.
