Old vessel with no any data.

Old vessel with no any data.

Old vessel with no any data.

(OP)
We have some old vessel with no any data eg. no as-built dwg, no U1A.  Can anyone recommend me, How to manage vessel like this accordance with API std 510 or in accordance ASME VIII Div1?

RE: Old vessel with no any data.

Check very carefully the heads of the vessel as there may be a NB/ASME number from which you can get a manufacturer's data from NB. The number U-1A would suggest a pressure vessel.

RE: Old vessel with no any data.

Is there a nameplate?

RE: Old vessel with no any data.

Regardless of what stamped inscriptions you find, you will be [should be] managing the remaining life of this used vessel i.a.w. API-510, API-RP-579-1/ASME FFS-1, and/or NBIC.

ASME Sect VIII *only* applies to new vessels.  As soon as a vessel gets 'wet' with process chemical(s), it no longer falls under Sect. VIII.  However, you will find that all the appropriate Codes will reverence back to Sect VIII in *some* instances.  This is why ASME reciently incorporated API's Recommended Practice RP-579 as their Fitness For Service FFS-1.  Prior to that, ASME had no provisions for evaluation of degraded vessels, no any provisions for making a 'true' repair.

By 'true' repair, I mean that the vessel would be Repaired - some remediation that brings the item into a condition that it can be safely left in service.  A Repair does not return the vessel to as-new condition.  What Sect VIII and most of NBIC call 'repairs' are Rework - returning the vessel to as-new condition.

On used vessels, Rework back to as-new may be too expensive, or too impractical.  If a Repair leaves the vessel in good enough condition to allow continued use, that may be the optimum 'real-world' remediation.  If everything had to be as-new, we would get new autos every 3-months or so.
