Can old blueprints be used to remanufacture an unfinished container that has been on hold for many years?

Thread Content

I would like to ask everyone: there is a heat exchanger that was not completed at the manufacturer due to the suspension of the project; it has been on hold for two years. Now this equipment is intended to be used in a similar installation at another location. Can the drawings, which were designed according to old regulations and standards, still be used?

Implementation Guidelines for TSG 21-2016 (Special Quality Inspection Letter No. 2016/46) I. Requirements regarding the transition period (II) Pressure vessels for which contracts were signed prior to October 1, 2016, or that were manufactured in accordance with the \"original regulations\", may still be completed and subject to supervision and inspection in line with the technical specifications specified in the contracts as well as the provisions of the \"original regulations\". If the project name is already indicated on the design layout, the original design firm should issue a revision order to make the change; otherwise, it will cause problems during the equipment registration process. Furthermore, this situation is after all an exception, and it should be discussed in advance with the inspection agency.

It must be carried out in accordance with the new standards; of course, the standards generally do not change much, so each one needs to be verified, and the factory documentation must be up to date.

It should be fine, but I need to communicate with the inspection unit first

It’s better to follow the new standards; if we use the old standards, it will be troublesome to communicate with the inspection agencies later on. Of course, if it’s easy to handle in this regard, we can just use the old drawings

It has been on hold for two years – that’s too long to deal with; it’s best to create new drawings according to the new standards...

In accordance with the implementation guidelines for (TSG 21-2016) (Special Circular on Quality Inspection [2016] No. 46): I. Requirements regarding the transition period...... II. Pressure vessels for which contracts were signed prior to October 1, 2016, or which were manufactured in accordance with the \"original regulations\", may still be completed and subject to supervision and inspection in line with the technical specifications specified in the contracts as well as the provisions of the \"original regulations\". ...... (IV) For design documents that were completed prior to October 1, 2016 and need to be used for manufacturing further (except those covered under item (II) of this paragraph), the parts of the design documents that are inconsistent with the provisions of the “New Solid Content Regulations” must be modified. -------------------------------------------------------- The situation of the poster no longer falls under clause (2); therefore, if the design permit is still valid, it can be handled in accordance with clause (4) ; If the design approval stamp expires, it cannot be used, and the design must be redone.

Agreed. In the case of the original poster, the original contract should actually be suspended; a new project requires a new contract to be signed. Therefore, the conditions specified in paragraph (ii) of Special Quality Inspection Letter No. 46 are not met, and redesign is necessary. For materials that have already been processed through welding, heat treatment, non-destructive testing, and other procedures, if they fully meet the dimensional and technical requirements specified in the new design documents, they can still be used after being re-inspected and confirmed, along with the preparation of new inspection documents. Of course, it should be agreed upon in advance with the owner, the designer, and the inspector.

I think it can no longer be used; the drawings are outdated and its design life has also expired.

Our quality inspection team directly refuses to approve it; the drawings must be redone first
