Current through Register Vol. 48, No. 38, September 20, 2024
a) When a safety or
safety relief valve is repaired, a metal repair nameplate stamped with the
information required by subsection (b) shall be attached and sealed by wire and
lead or metal seal stamped to the valve either above, adjacent to or below the
original stamping. See Section 2120.1250(b) for exception.
b) As a minimum, the information on the valve
repair nameplate shall include the name of the repair organization and the date
of repair. If set pressure has been changed, then the new pressure setting, as
well as the blowdown (for "V" stamped valves), and new capacity shall be
indicated. The original nameplate or stamping shall be marked out but left
legible. The new capacity shall be based on that for which the valve was
originally certified.
c) Illegible
or Missing Nameplates
1) When the information
on the original manufacturer's or assembler's nameplate or stamping is
illegible, the nameplate or stamping shall be augmented or replaced by a
nameplate stamped "duplicate" that contains all information that originally
appeared on the nameplate or valve, as required by the applicable Section of
the ASME Code, except the "V" or "UV" symbol and the National Board mark. The
repair organization's nameplate and other required data specified in subsection
(b) will make the repair organization responsible to the owner and the Division
for the information on the duplicate nameplate being correct.
2) When the original valve nameplate is
missing, the repair organization is not authorized to perform repairs to the
valve under the program unless positive identification can be made to that
specific valve and verification that the valve was originally stamped with a
"V" or "UV" stamp. Valves that can be positively identified shall be equipped
with a duplicate nameplate as described in subsection (c)(1), in addition to
the repair organization stamped nameplate. The repair organization
responsibilities for accurate data as defined in subsection (c)(1) shall
apply.
3) When a duplicate
nameplate is affixed to a valve as required by subsection (c)(1) or (c)(2), it
shall be marked "Sec I" or "Sec VIII", as applicable, to indicate the original
ASME Code stamping.
