Valves and Wellhead Equipment
Requirements Per API SPEC 6A
(ADDITION) PSL 4 A Pre-inspection meeting between the primary
manufacturer and Buyer's Inspection Representative is required for all
PSL-4 equipment. The meeting must be held before any action against the
order is taken by the manufacturer as soon as possible after receipt date of
the order.
As a minimum, the meeting shall include the manufacturer's
representatives of Production, Engineering and Quality Assurance
Departments and the Buyer's Inspection Representative. The meeting's
objective will be to discuss the assigned specification, identify, clarify and
document any technical areas or question of difficulty. The Buyer's
Inspection Representative shall be acting for the RSA, but the RSA shall
have the final approval of any deviation from the assigned specification or
procedures.
In the event material ordered is "stock" material, an exception to this
specification can be approved by the RSA. Request for this exception
must be submitted to the Buyer in writing in no more than thirty (30)
calendar days after initial contact between the Manufacturer and Saudi
Aramco. The initial contact date is determined and documented (and the
Manufacturer advised of that set date) by the assigned Buyer's Inspection
Representative.
605.2a(3)
(ADDITION) PSL 1-4 Each piece of 10M psi rated equipment listed in
the drawing of Appendix A shall have its hardness tests performed in the
locations so marked on the appropriate manufacturer's representative or
generic drawings located in Appendix A.
If equipment being manufactured is not included in Appendix A, hardness
tests are to be per the manufacturer's normal procedures.
605.2b(9)
(ADDITION) PSL 2-4 For non-ferromagnetic materials, all liquid
penetrant inspections shall be performed using fluorescent penetrant.
605.2c(10) (ADDITION) PSL-3 only All equipment rated at 10M psi working
pressure or above must have prior approval (via Saudi Aramco
Manufacturer's Deviation Review Procedure (AMDR) (see Appendix D
for details) before any weld repairs may be made.
605.2c(14) (ADDITION) PSL 3-4 Volumetric testing of cast materials shall be done
by radiography. Forgings shall be ultrasonically tested. In the event the
prescribed test method is impractical, the Buyer's Inspection
Representative shall approve an alternative method of testing during the
Pre-Inspection meeting. In the event there is no pre-inspection meeting

required, approval of alternate method must be made before production of
the equipment begins.
(MODIFICATION) PSL 3-4 Hot Worked Parts - Ultrasonic examination
of hot worked parts shall be performed in accordance with both the flat
bottom hole procedures (straight beam examination) and applicable angle
beam examinations specified in ASTM A388 (except immersion method
may be used) and ASTM E428.
(ADDITION) PSL 3-4 Castings - Angle beam examination in accordance
with ASTM A609 shall be applied when any area of the casting cannot be
effectively examined using a longitudinal beam due to casting design or
possible discontinuity orientation.
(ADDITION) PSL 3-4 Acceptance Criteria, Castings - Castings
examined in accordance with ASTM A609 shall meet Quality Level 1
(Table 2 "Rejection Level") requirements.

(ADDITION) PSL 1-4 All cast body equipment - Prior to hydrostatic test
of cast body equipment, an acid bath of 15% unihibited HCL is required.
An immersion time of 15 minutes is required. In addition, all cast body
equipment (of all pressure ratings) require both hydrostatic and gas tests to
working pressure after acid bath.
605.9c(5)
(ADDITION) PSL 1-4 Functional tests of all valves shall be conducted at
full differential pressure between 1st and 2nd seat tests. Valves ordered
with actuators shall be tested with actuator installed.
605.9e(4)
(ADDITION For Body Tests On 10M psi Or Above Equipment)
PSL 1-4 100% of the equipment shall also be nitrogen gas tested as per
PSL-4 requirements. Should each flange of the equipment carry a
different working pressure, only the 10M flange is to be gas tested. See
Appendix B drawings.

Saudi Aramco Manufacturer's Deviation Review Procedure (AMDR)
This procedure is to be used when any deviation from the assigned Specification,
Procedure or Purchase Order description is noted by Buyer's Inspection Representative
or the Manufacturer's Inspection Department.
I.
This section is the "formal" AMDR process and will only pertain to all equipment
produced under API SPEC 6A PSL-4 service level rating.
A.
Buyer's Inspection Representative (BIR) is advised of the deviation by the
Manufacturer (or finds the deviation in their inspection process).
B.
Saudi Aramco Vendor Inspection (SAVI) evaluates the problem and
determines if the situation constitutes the use of the balance of this section of
the AMDR Procedure. If this formal section is not required by SAVI, use
procedure in section 2 (informal) to obtain deviation approvals.
C.
If the procedure is required, SAVI advises the Manufacturer to submit a full
report and advises the RSA and Buyer of the deviation. If applicable, the
Manufacturer should notify the Vendor.
The Manufacturer's full report shall consist of a complete explanation of the
problem and their proposal to repair or correct the deviation. The report
shall contain drawings if there is any doubt as to a text explanation giving a
complete picture of the nature and/or location of the problem. In addition, it
will state the length of delay (if any) the proposed repairs or corrections will
have on the delivery of the complete order. The report shall be reviewed by
the manufacturer's Chief Quality Engineer (or the Manufacturer's titled
equivalent). He/she shall then draft a cover letter for the report on his
letterhead concurring with the proposed repair and/or corrections.
D.
Upon receipt of the report, SAVI will:
1.
Log the report using the following format:
a.
XMDR-AOC(or ASC)-87-YYY-000-ZZ
b.
The "X" is the first letter in the Manufacturer's name.
c.
The "87" is the current year.
d.
The "YYY" is the sequentially numbered report for the subject
order number.
e.
The "0000" is the last 4 digits of the subject order number.

f.
The "ZZZ" is the first letters of the location of the Manufacturer's
plant. For example, AOC would use "SIN" to identify Gray's
Singapore plant.
g.
An example number would be:
CMDR-AOC-91-003-8926-SIN.
This number would indicate AOC 1991 report number 003
concerning order 8926 being made in Gray's Singapore plant.
II.
E.
The RSA shall review the report and consult with any appropriate
organizations for information and approvals (if required) resulting in the
resolution of the matter.
F.
The RSA shall advise the SAVI and the Buyer of its findings and
recommended actions. The disposition shall be reported to the Manufacturer
by SAVI.
G.
If the disposition from the RSA has a commercial impact against the
Manufacturer and/or the Vendor, the matter is resolved between said parties
and the Buyer.
H.
If the Vendor and/or Manufacturer is not satisfied and wishes to appeal the
case, he can submit another report or clarification to the original report. This
can be done through the channels of communications described above. The
appeal must be made within thirty (30) days of the date of the RSA's issue of
the disposition. This set time limit shall also pertain to any and all additional
appeals to the deviation disposition.
This section pertains to equipment made under PSL ratings 1-3.
A.
Buyer's Inspection Representative (BIR) is advised of the deviation by the
Manufacturer (or finds the deviation in their inspection process).
B.
BIR advises SAVI of deviation and Manufacturer advises his Vendor and
the Buyer.
C.
A full informal report is submitted to the RSA by SAVI. This informal shall
be in writing (telex or fax); but does not require an assigned log number or
formal review and documentation from the Manufacturer's executive quality
assurance management.
D.
The RSA findings will be issued per paragraph F. in Section I.
E.
Paragraph G. of Section I shall also apply to this informal process.

The Vendor and/or the Manufacturer will retain the ability to appeal the
RSA's findings in this informal process. They may appeal using the same
process described in this section within a thirty (30) day period from the date
of the RSA's issue of the disposition.
