【Daily Question】

1. Is it illegal to manufacture the equipment at Location B? How should equipment supervision be corrected? It depends on whether the registered geological supervision authority issues a manufacturing inspection certificate for him. 2. Does the head factory need to issue an inspection certificate for the heads? I’ll just shape the melon slices for you; no certificate should be issued. 3. Does the final non-destructive testing report require the signature of the manufacturer? Needed

Answer: 1. The supervisor should submit a deviation to the factory regarding manufacturing at Location B. Location B falls outside the scope of the pressure vessel manufacturing license issued by the manufacturing unit; therefore, a permit for off-site manufacturing of the project must be obtained from the provincial authorities. 2. Not necessary. 3. Required

1. Site B is non-compliant for the following reason: the equipment manufacturing certificate does not include Site B, and container manufacturing processes related to regulatory requirements cannot be carried out at Site B. Site B should obtain its own certification or have its operations included in the certification for Site A. 2. The head factory does not carry out welding work, so it is not required to have supervision during inspection ； 3. Weld inspection is outsourced; the entrusted party must possess the appropriate qualifications, and the manufacturing plant must have a compliant outsourcing authorization letter ； A report is issued by the non-destructive testing service provider ； The manufacturer shall include the qualified test reports (with relevant information on any repairs made in the case of defective items) in the equipment quality certificate; no signature is required.

This is the kind of problem that arises in EPC projects for pressure vessels

Those who have worked on mobile factories know these requirements
