One of our flange vendors have used Sptroscope JR for performing PMI on SDSS (ASTM A182 F53) flanges.
It is violating two of our requirements
1. Our purchase requisitions wants vendor to remove any PMI marks before supplying the items to us, vendor did not comply
2. Our construction specification allows us only XRF machines for PMI, we did not take this into consideration while approving vendor’s PMI procedure.
Vendor has advised the marks shall only be removed by grinding and their pickling and passivation which was shown as the last stage in the manufacturing ITP was not able to remove the marks.
Now that the items are at our site Please advise
1. If there is any adverse metallurgical effect on the SDSS material because of the sparking on the surface?
2. We have tried removing the spark marks by touching it by pencil grinder and is getting removed is that advisable?
Regards,
