2.0 GENERAL

2.1 PURPOSE

This document defines the requirements for po sitive material identification (PMI) for all
equipment, piping and instrumentation including those items supplied as part of a skid
package and also for bulk piping items.

PMI shall ensure that the specified alloy mate rials are supplied and/or have been used for
all the components of a finish ed assembly or equipment.

This WorleyParsons general standard has been amended to align with the requirements of
CPMS-MAT-EP-006.

2.2 SCOPE

PMI shall be carried out for all alloy material s (i.e. austenitic, duplex and super-duplex
stainless steels, nickel alloys), non-ferrous alloys (i.e. cupro- nickels, titanium alloys) and
low alloy steels (i.e. CrMo steels and 3½Ni, 5Ni steels).

Carbon steel, carbon-manganese steels, TMCP steels or micro-allo yed steels shall not
require PMI testing.

PMI shall be performed through all stages of fa brication (shop and site) and when there is a
risk of material mix-ups occurring such as during transportation or stockage. This may
result in individual items being su bject to PMI at several occasions.

PMI shall be applied during shop fabrication an d during site fabrication for field assembled
items. Where required by this specification PMI shall also be carried out on welds.

PMI shall be applied in addition to the manuf acturer’s/supplier’s overall quality assurance
requirements for materials and shall not be used as a replacement or substitute for
Certified Material Test Reports and other QA requirements.

The extent of PMI is defined in Section 3.

PMI testing may be performed prior to post weld heat treatment if required.

All tested items shall be marked in accordance with Section 5 and a report form issued,
refer to Section 6.



2.3 RESPONSIBILITIES

It is the responsibility of the SUPPLIER to perform the PMI and/or to ensure it is performed
by other sub-suppliers in accordance with this specification. For material and components
where PMI was undertaken by others, the SUPPLIER is responsible for confirming that PMI
was performed by the checking of markings on components and inspecting PMI reports on
assembled items.

The SUPPLIER shall submit a PMI procedure to the COMPANY for review prior to commencing
the work. In-house PMI procedures employed by material suppliers, manufacturers and
other sub-suppliers shall be subject to COMPANY review. The SUPPLIER shall review the
sub-supplier PMI procedures to ensure they meet the requirements of this specification
before submitting them for COMPANY review.

Final acceptance by the COMPANY of any material, equipment or pipe spool etc shall
require PMI in accordance with this specification. PMI may be witnessed or confirmed by
independent testing by the COMPANY or a third party inspector.

3.0 EXTENT

3.1 GENERAL

PMI testing should be carried out at a time and location that enables simple corrective
action should it be necessary to replace materials (i.e. during procurement and sub-
assembly). However, for bulk piping componen ts this does not negate the requirement of
testing after fabrication.

The minimum sampling frequency for PMI is defined below, for items/components
represented by a heat, lot or batch the indicated percentage shall be selected randomly.

3.2 FABRICATION

3.2.1 Equipment

Equipment includes vessels, columns, burners, pumps, tanks, heat exchanger air coolers,
heaters, piping components, instruments an d accessories, skid mounted equipment and
associated piping. PMI testing shall be perf ormed following assembly and prior to coating
and may be performed prior to post weld heat treatment.

All pressure containing, alloy material shall be subject to PMI as follows:

1. All plate material, 100 %

2. Items fabricated from material no t previously alloy verified, 100%

3. All alloy material, pressure-containing piping components (includes pipe or tube used
for heater coils and instrumentation c omponents) used for the fabrication of
equipment, 100 %

4. 10% of alloy bolting including L7/B7 grade bolt s, or 1% if the bolting can be proven as
originating from a previously alloy verified batch. Galvanised bolting need not be
tested at equipment fabr ication stage see 3.2.3.

5. Welds as per Clause 3.3

3.2.2 Shop and field fabricated pipe spools


On receipt of all materials the SUPPLIER shall check that PMI has been carried out before
dispatch from the stockist or manufacturer as pe r Clause 3.2.3. If any material has not been
subjected to PMI the SUPPLIER shall conduct PMI on receipt of the materials to the same
extent described in Clause 3.2.3.

Following fabrication all pressure retaining it ems shall be subject to alloy PMI as follows:

1. All alloy piping, piping comp onents such as valves (bodies only), nozzles, flanges,
fittings, couplings, instrument tubing an d instrument components etc for the main
process streams shall be subjected to 100% PMI testing.

All other piping and instrument system s shall be subject to 5% testing per
batch/heat/lot with a minimum of 4 lengths being tested. The pipe must be
positively identified as belonging to th e batch/heat/lot throughout fabrication.

2. Pipe that cannot be proven as originating from an alloy verified batch shall be 100%
tested.

3. Piping components that cannot be proven as originating from an alloy verified batch
shall be 100% tested.

4. 10% of alloy bolting including L7/B7 grade bolt s, or 1% if the bolting can be proven as
originating from a previously alloy verified batch. Galvanised bolting need not be
tested at spool fabrication stage see Clause 3.2.3.

5. Welds as per Clause 3.3

1.0 NOTES TO TABLE – APPENDIX 2

1. Testing of C is not required unless specif ically indicated on the data sheet or
purchase documents.

2. Testing of Ti will prevent unacceptab le substitution with Grade 409.

3. In the event that a generic alloy “match” by a portable alloy analyzer cannot be
achieved then the following elements shall be quantitatively determined. Refer to
Section 5 of this specification.

4. A “match” by a portable alloy analyzer is acceptable; refer to Section 5 of this
specification.

5. If the portable analyzer is unable to prov ide the degree of accuracy for these lower
nickel alloys the verification shall be by chemical analysis approved by the COMPANY.

6. Alloy materials not listed shall be referred to the COMPANY for elemental
requirements.

7. L7/B7 bolts and nuts as per ASTMs A193/A194 respectively.
